AJMRTC LM75A temperature sensor module is a digital thermal sensing board with I2C interface. It converts ambient temperature into digital signals with high precision and supports over-temperature trigger output. You can set alarm threshold and hysteresis value through programming. Multiple modules can be connected on the same I2C bus by configuring address pins. It works perfectly with Arduino, ESP32 and STM32 for cabinet temperature monitoring, fan automatic control and industrial thermal protection systems. This package contains two sensor modules for multi-point temperature collection and spare backup.
