Sensor-Temp&Hum

The product number of Sensor-Temp&Hum is: MSDT31 Sensor-Temp&Hum is a humidity and temperature detection module.

AM2321 contains a capacitive humidity component and a high precision integrated temperature measuring component, and it is connected with a high performance microprocessor.

Introduction of Sensor Pins

Pins of the sensor: PIN1: GND PIN2: VCC General signal pins: PIN3(IO1): digital/analog signal PIN4(IO2): NC(null) Special signal pins: If it is IIC: IO1/IO2 are respectively SDA/SCL. If it is soft serial port: IO1/IO2 are respectively tx/rx.

Special to Sensor-Tem&Hum-S2 sensor pins PIN1: GND PIN2: VCC PIN3(IO1): SDA PIN4(IO2): SCL Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.
