LM YN Atmospheric Temperature Communication Review

The GY-39 is a 4-in-1 module that contains air pressure, temperature, humidity, and light intensity sensor modules. Working voltage 3-5v, power consumption is small, easy to install. How it works: MCU collects a variety of sensor data, unified processing, direct output after the calculation of the results, this module has two ways to read the data, that is, serial port UART (TTL level) or IIC Serial baud rate of 9600bps and 115200bps, configurable, continuous and interrogated output in two ways. Can be saved to save settings. Can adapt to different working environment, and single-chip and computer connection. The module can be set to a separate sensor chip operating mode, as a simple sensor MAX44009 or BME280 module used, MCU does not participate in data processing work. We can provide arduino, 51, stm32 microcontroller communication procedures, if necessary, please contact us. Applications: Digital lighting management, Internet of things, intelligent home applications, Weather station monitoring, Digital light meter, Digital barometer, altimeter thermometer , Greenhouse climate monitoring.
