4 Channel Touch Sensor

This easy to use capacitive touch switch can operate between 2V and 5.5V, so is ideal for using with your Micro:bit, Raspberry Pi, ESP8266 or Arduino. This module acts as a momentary button. When the module does not detect a finger, it requires around 13uA, and around 2mA when you are activating it with your finger (Due to the onboard LED).
