Microduino-TOUCH

The product number of Microduino-TOUCH is: MSDS21

Microduino-TOUCH is capacitive touch detection sensor module.

After the human body touch the two ends of the capacitance, the touch sensor can conduct electricity via the human body tissues and fluids, so the two ends of it change into low level.

Breaking the touch, the capacitor starts charging in an instant, until the rated capacity of the capacitor, and at this time, the two ends of the capacitor is equivalent to open circuit, and the two ends of the touch sensor change into high level.

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.
