GY-39 MAX44009 BME280 Sensor Module GY-39-44009 Temperature and Humidity Sensor UART IIC TT Electronic DIY Board
Product Introduction
GY-39 is a low-cost low-power detection of pressure, temperature and humidity and light intensity sensor module,
Its working principle is that the on-board MCU collects various sensor data and outputs the calculated result directly
after the unified processing. This module has two ways to read the data, namely serial UART (TTL level) or IIC (2 lines);
there are two ways of continuous and inquiry output, save power-down settings, adapt to different working environment
and single-chip computers and computers connection.
Provide For Arduino, 51, STM32 microcontroller communication program, but does not provide schematics and internal
microcontroller source; In addition, giving Andrews mobile phone software APP view data, and supports WiFi intranet
connection, mobile phones and computers at the same time display data.
Note: The module can be set up a separate sensor chip mode of operation, as a simple sensor module, MCU
does not participate in data processing.
