AJMRTC SHT31-D Digital Temperature Humidity Sensor Breakout Module, High Precision I2C Humidity & Temperature Detector Board for Arduino ESP32 STM32 Weather Environmental Monitoring DIY

AJMRTC SHT31-D temperature and humidity breakout module uses the SHT31-D digital sensor IC from Sensirion. It delivers highly reliable environmental readings compared with older sensors such as SHT20 and SHT21. It communicates over the I2C bus, requiring only two signal lines plus power. It supports a built-in heating function to evaporate surface moisture and avoid measurement drift in high-humidity environments. The module works well with Arduino, ESP32, Raspberry Pi and STM32 control boards. It is widely used for greenhouse monitoring, smart home weather stations, incubator control, cabinet environmental detection, storage room humidity tracking and electronic STEM projects.
