Microduino-Sensor-Temperature-D1

The product number of Sensor-Temperature-D1 is: MSDT11

Sensor-Temperature-D1 is digital temperature detection sensor module.

LM75 is a temperature sensor produced by National Semiconductor whose output voltage is of Celsius scale.

Introduction of the Sensor Pin

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-Temperature-D1 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.
