Microduino-TOUCH

The product number of Sensor-Touch Button is: MSDS21

Sensor-Touch Button is capacitive touch button sensor module.

Introduction of 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-Touch Button sensor pins PIN1: GND PIN2: VCC PIN3(IO1): Digital signal input PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.
