Key points:
1. The high level time of the output of this product is adjustable, 2.5 seconds to 1 hour, the output time set at the factory.
It is 2.5 seconds, and you can change one chip resistor if you need to change it. Please read the resistance value corresponding to the typical delay time.
Refer to the relevant form below.
2. Blocking time, 2 seconds, not adjustable.
3. The factory is defined as repeatable trigger and cannot be changed.
4. The supply voltage of this module is 3.3V to 15V, and the limit voltage is 2.8V to 18V.
5. Module output timing is: output high level for 2 seconds after power-on, then go low, enter standby
status. If the delay time is changed, the time when the module outputs a high level after power-on will increase accordingly, which can be understood as
The startup time after entering the normal working state after the electric power will increase.
6. After installing the photosensitive element, it does not work during the day, work at night, does not contain photosensitive components, and works all day ( There are no photodiodes on the module,please purchase separately if needed. Recommended: ordinary F3 photodiode )
It is considered that there is no photosensitive element installed.
7. This module is very sensitive, pay attention to the installation position, try to avoid the heat source radiation source (air outlet / direct sunlight)
8. The sensitivity of this module is adjustable, and you need to change a chip resistor. Please read the relevant table below for details.
grid.
9. When soldering with 220V ordinary soldering iron, it is necessary to unplug the power supply before welding. It is recommended to use
24V low voltage soldering iron, such as domestic white light 936.
10. If you follow the MCU and connect the lamp, please read the reference circuit diagram below.

Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions) Product Size: 45*15*3.4mm (Standard), 48*20*3.4mm (Balancing) Charging voltage: 8.4V - 9.0V Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current use) Continuous charge current (upper limit): 10A Standard Edition: Suitable for starting drills with currents up to 25A below 50W, or resistive loads below 168W. Balanced version: Suitable for starting currents below 25A and below 50W power drills, or resistive loads below 168W, with balanced charging function. Note 1: The successful start of power drill requires two 10C-20C power batteries, or four 5C-10C power batteries (ordinary 18650 can not start drill! ! !); 0V and 8.4V cable, use 2 square mm Above copper wire (cannot use nickel plate!!!) Note 2: Connect 0V, 4.2V, 8.4V according to the diagram strictly. When connecting the battery for the first time, it needs to be charged before output. Note 3: When the battery is charged, “430” resistance heating is a normal phenomenon, indicating that the equalizing circuit is working; if the “430” resistance is also heating in the state of not charging, please check whether the wrong line is connected. For some customers with poor electronic foundation, please explain: Do not mix good batteries and bad batteries together! The capacity/internal resistance of 2 batteries should be as close as possible! (1 good battery 1 bad battery = 2 battery use effect).

Description:
1. This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can't be higher than VCC), and the connections function in either direction. To control it, connect 4 digital outputs to the chip's address select pins (S0-S3), and send it the binary address of the channel you want (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins!
2. Since the mux/demux also works with digital signals, you can use it to pipe TTL-level serial data to or from multiple devices. For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller. You can then select any one of those 16 devices to listen to. If you want two-way communications, you can add a second board to route your microcontroller's TX line to 16 device's RX lines. By using multiple boards, you can create similar arrangements for I2C, SPI, etc.
3. The internal switches are bidirectional, support voltages between ground and VCC, have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching. The board also breaks out the chip's “enable” pin, which when driven high, will completely disconnect the common pin (all switches “off”).

Please receive this module and leave it in the environment with humidity greater than 80% for 12 hours to ensure the accuracy is restored.
The AHT10, a new generation of temperature and humidity sensors, sets a new standard in size and intelligence: it is embedded in a dual-row flat leadless SMD package for reflow soldering with a 4 x 5mm bottom and a height of 1.6mm.
The sensor outputs a calibrated digital signal in standard I 2C format.
The AHT10 is equipped with a newly designed ASIC-specific chip, an improved MEMS semiconductor capacitive humidity sensing element and a standard on-chip temperature sensing element.
Its performance has been greatly improved beyond the reliability level of previous generation sensors. The first generation of temperature and humidity sensors have been improved to make them more stable in harsh environments.

ESP8266 CH340 V3/ESP8266 CP2102 V2 /ESP8266 ESP32
1.Open-source
2.Interactive
3.Programmable
4.Low cost
5.Simple
6.Smart
WI-FI enabled
Ard--uino-like hardware IO
Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.
Code like ard--uino, but interactively in Lua script.
Nodejs style network API
Event-driven API for network applicaitons, which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style.
Greatly speed up your IOT application developing process.
Introduction:
ESP32 is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters,
and power management module. The entire solution takes up the least amount of printed circuit board area.
This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology,
power and RF properties best, which is safe, reliable, and scalable to a variety of applications.
Features:
High performance-price ratio
Small volume, easily embeded to other products
Strong function with support LWIP protocol, Freertos
Supporting three modes: AP, STA, and AP STA
Supporting Lua program, easily to develo
