SPECIFICATIONS

GYMCU680 is a low-cost air detection module with a low operating voltage of 3-5v and a small size.

The working principle is to read the BME680 sensor data through the MCU, and obtain the algorithm, temperature and humidity, atmospheric pressure, IAQ indoor air quality, and resistance value.

This module has two ways to read data, namely serial port (TTL level) or chip itself IIC communication mode.

The product has high precision and high stability. It is possible to directly output utility data and omit the algorithm.

The baud rate of the serial port is 9600bps and 115200bps. There are two modes of continuous output and interrogation output, which can adapt to different working environments.

Connect to all microcontrollers and computers

When soldering the PS solder joint, the module is in the chip's own IIC mode, at which point the MCU does not participate in the operation and does not consume current. Can be used as a simple BME680 module.

The IAQ indoor air quality algorithm is transplanted according to the routine of the BME680 chip official website. It takes a certain time to power on the test, and the data will be normal for about 5 minutes.
