Description
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.
