BBS:http://mh.nodebb.com Product introduction: The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. 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.

Description: Heart Rate click carries Maxim's MAX30100 integrated pulse oximetry and heart-rate sensor. It's an optical sensor that derives its readings from emitting two wavelengths of light from two LEDs - a red and an infrared one - then measuring the absorbance of pulsing blood through a photodetector. This particular LED color combination is optimized for reading the data through the tip of one's finger. The signal is processed by a low-noise analog signal processing unit and communicated to the target MCU through the mikroBUS I2C interface. Developers of end-user applications should note that the readings can be negatively impacted by excess motion and changes in temperature. Also, too much pressure can constrict capillary blood flow and therefore diminish the reliability of the data. A programmable INT pin is also available. Uses 3.3V power supply. Key features: Optical sensor: IR and red LED combined with photodetector Measures absorbance of pulsing blood I2C interface plus INT pin 3.3V Power supply Key Benefits: Motion artefact resillence Ambient light cancellation Ready-to-use examples save development time Supported in all MikroElektronika compilers Applications Developing algorithms for pulse oximetry and heart rate readings through the tip of a finger.

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
 
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

How to install the driver
 
win7 / win8 
1, first open the package, like the way next, remember installation directory 
2, according to the following method to start the service 
3. Locate the driver in Device Manager, select Update Driver, browse my computer for driver,
select the directory just installed, determine waiting like
 
win8.1
 
Right update drivers automatically find the drivers, it will prompt the driving data is invalid, in fact, the problem often encountered in windows8, the drive is no problem, the beginning has been installed on, and later discovered may be a hardware incompatibility. 
If you are using Windows8 or windows 8.1, but is non-genuine ghost or other systems, and uses a variety of optimization tools Streamlining system, then in the process of installing the driver, you may encounter the "Data invalid" wrong 
"Invalid Data" solutions are as follows:
 
1, press Winkey R on the keyboard, the pop-up "Run" dialog, enter "services.msc",
also by under "Computer Management" window, find the "service"; 
2, found in the list of services "Device Install Service" and "Device Setup Manager" two service items,
make sure these two services is turned on, if not open, you can click the left side of the "Start" service.
