TTP229 Capacitive Touch Sensor

The ttp229 component allows you to use your TTP229 datasheet Capacitive Touch Sensor with ESPHome.

There are two types of this sensor:

  • ttp229_lsf: The I²C version of the sensor, uses SDA+SCL pins.
  • ttp229_bsf: The pin-based version of the sensor, uses SDO+SCL pins.
