3pcs AT42QT1070 5-Pad 5 Key Capacitive Touch Screen Sensor Module Board DC 1.8 to 5.5V Power For Standalone Mode

Features This board is the simplest way to create a project with multiple capacitive touch sensors No microcontroller is required here just power with 1 8 to 5 5VDC and connect up to 5 conductive pads to the 5 left hand pins When a capacitive load is detected e g a person touches one of the conductive contacts the corresponding LED on the right lights up and the output pin goes low You can use this to update an existing normal button project where buttons connect to ground when pressed Note that one contact will be detected at once this is to protect against having a hand brush against two or more contacts at once The datasheet has many details on sensitivity power usage etc note that this board uses the chip in standalone mode it cannot be used in I2C mode Specification Model AT42QT1070Type 5 Pad Capacitive Touch SensorPackage includes 3 x Capacitive Touch Sensor Board
