Product Description
1. The AMG8833 infrared camera sensor is an 8x8 infrared thermal sensor array. When connected to your microcontroller (or Raspberry Pi), it will return a set of 64 individual infrared temperature readings via I2C. It's like those fancy thermal cameras, but it's compact and simple and easy to integrate. The AMG8833 offers higher performance than the previous AMG8831. The sensor only supports I2C and has a configurable interrupt pin that can be triggered when any single pixel is above or below your set threshold.
2. It can detect humans from a distance of up to 7 meters (23) feet. It is a perfect fit for creating your own human detector or mini camera. We use this breakthrough code on or compatible (sensor communicates via I2C) or on Python's Raspberry Pi. On the Pi, thanks to the image processing help of the SciPy python library, we can insert an 8x8 grid and get some very good results!

 Color of the PCB would be black or purple randomly.

1, Size: 37mmX45mmX8mm
2, the main chip: HB100
3, work voltage: DC 5V
4,HB100 is the use of microwave Doppler radar module (Doppler Radar) design principles of the microwave detector moving objects, mainly used in automatic door control switches, security systems, ATM ATM automated video control systems, automatic train signal, etc. place. HB100 is the standard 10.525GHz microwave Doppler radar detector, the detection method compared with other detection methods have the following advantages: 1, non-contact detection; 2, independent of temperature, humidity, noise, air, dust, light other effects, suitable for harsh environments; 3, anti-RF interference ability; 4, the output power is small, constitute a hazard to humans; 5, distance: more than 20 meters detection range.
5,Doppler Principle: Doppler theory based on time, when radio waves encounter an object in the moving process will be reflected when the waves, the frequency of the reflected wave will hit the object with the movement to change state. If the radio waves encounter an object position is fixed, then the reflected wave frequency and transmitting frequency waves should be equal. If the object moves toward the launch, then the reflected waves will be compressed, that will increase the frequency of the reflected wave; otherwise the reflected wave's frequency decreases.

Descirption:
 
 
This module is a plant watering alarm - as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant. Chirp uses capacitive humidity sensing as opposed to resistive humidity sensing, this means, it does not make an electric contact with the soil, avoiding electrode corrosion and soil electrolysis and resulting in better accuracy and longer battery life.
 
Special care has been taken not to make it yet another source of annoyance - Chirp will be silent when it's dark and will restrict itself from making too much noise.
 
The alarm level can be set for each plant individually. As water is consumed by the plant, Chirp will detect the low moisture level and will start to emit rare short chirps. As more water evaporates, Chirp will increase the alarm rate. Chirp can detect if it's day or night by measuring the amount of ambient light and will not make noise when it's dark.

​Descriptions:
 
 
The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. This board is a carrier for the VL53L0X, so we recommend careful reading of the VL53L0X datasheet (1MB pdf) before using this product. 
The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object's reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor's accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.) 
Ranging measurements are available through the sensor's I⊃2;C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output. 
The VL53L0X is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible. 
  
PIN     Description 
VDD  Regulated 2.8 V output. Almost 150 mA is available to power external components. (If you want to bypass the internal regulator, you can instead use this pin as a 2.8 V input with VIN disconnected.)
 
VIN  This is the main 2.6 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I⊃2;C lines high to this level.
 
GND  The ground (0 V) connection for your power supply. Your I⊃2;C control source must also share a common ground with this board.
 
SDA    Level-shifted I⊃2;C data line: HIGH is VIN, LOW is 0 V
 
SCL      Level-shifted I⊃2;C clock line: HIGH is VIN, LOW is 0 V
 
XSHUT    This pin is an active-low shutdown input; the board pulls it up to VDD to enable the sensor by default. Driving this pin low puts the sensor into hardware standby. This input is not level-shifted.

The The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows the INMP441 to be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system. The INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications. The INMP441 has a flat wideband frequency response that results in high definition of natural sound. Product Features: 1. Digital I2S interface with high precision 24-bit data 2. High signal to noise ratio is 61 dBA 3. High sensitivity - 26 dBFS 4. Stable frequency response from 60 Hz to 15 kHz 5. Low power consumption: low current consumption 1.4 mA 6. High PSR: -75 dBFS Interface definition: SCK: Serial data clock for I2S interface WS: Serial data word selection for I2S interface L/R: Left/Right channel selection. When set to low, the microphone outputs a signal on the left channel of the I2S frame. When set to high level, the microphone outputs signals on the right channel SD: Serial data output of the I2S interface. VCC: Input power, 1.8V to 3.3V. GND: power ground This product provides tutorials for using ESP32 modules with I2S functionality. Connect to ESP32: INMP441 ESP32 SCK >> GPIO14 SD >> GPIO32 WS >> GPIO15 L/R >> GND GND >> GND VDD >> VDD3.3 What is the difference between an omnidirectional microphone and a unidirectional microphone: First of all, I understand that the sound divergence is all-round. One person speaks and diverge in the air. As for how far it can pass, it depends on many factors. 1.directional microphone, the general pickup radius is very small, 30 cm is a big one, single use, put it on the mouth, the sound quality is very good, because it is not picked up again. The shape is generally goose neck wheat, a rod, a curved rod, to your mouth, directivity, just listen to your voice. With a single-point microphone, the sensitivity is limited to a certain range. Sensitivity is too high, causing sharp whistling, etc., involving many other devices As for why not make a big pickup radius, there is a reason. Later 2.omnidirectional microphone, the general pickup radius is very large, one meter two meters three meters five meters have, compared with ten centimeters, this level is very different, it is not just picking a person's voice, but Multiple people, five six, seven eight or even ten. Omnidirectional microphones are highly sensitive, The omnidirectional microphone pickup radius is too large, and it will also pick up more ambient noise, so the sound quality is not as good as the single-point microphone, unless you do a good noise reduction. There is definitely a difference between collective use and single-person service. But omnidirectional wheat has a benefit, the wiring is simple, not one by one. Suitable for small meetings, ad hoc meetings, some remote discussions, remote operations. 3.single-point wheat generally supports local amplification, Omnidirectional microphones generally do not support local amplification. It should be noted that because of such high sensitivity, the local amplification whistling is very scary, and the current technology is difficult to deal with.

GY-21 HTU21D Temperature Humidity Sensor Breakout Board Module
The HTU21D is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor.
This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems.
All you need is two lines for I2C communication and you'll have relative humidity readings
and very accurate temperature readings as a bonus!
There are only four pins that need to be hooked up in order to start using this sensor in a project.
One for VCC, one for GND, and two data lines for I2C communication.
This breakout board has built in 4.7k pull up resistors for I2C communications.
If you're hooking up multiple I2C devices on the same bus, you may want to disable these resistors.
It's summer and you're sweating and your hair's all frizzy and all you really want to
know is why the weatherman said this morning that today's relative humidity would max
out at a perfectly reasonable 52% when it feels more like 77% .
Enter the HTU21D-F Temperature Humidity Sensor - the best way to prove the weatherman wrong!
This I2C digital humidity sensor is an accurate and intelligent alternative to the much simpler
Humidity and Temperature Sensor - SHT15 Breakout It has a typical accuracy of ±2% with an
operating range that's optimized from 5% to 95% RH. Operation outside this range
is still possible - just the accuracy might drop a bit. The temperature output has
an accuracy of ±1°C from -30~90°C. If you're looking to measure temperature more accurately,
we recommend the MCP9808 High Accuracy I2C Temperature Sensor Breakout Board.
 
Such a lovely chip - so we spun up a breakout board that includes the
Filtered version (the white bit of plastic which is a PTFE filter to keep the sensor clean),
a 3.3V regulator and I2C level shifting circuitry. This lets you use it safely with any kind
of microcontroller with 3.3V-5V power or logic. Each order comes with one fully assembled
and tested PCB breakout and a small piece of header.
You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.
