MPR121 Capacitive Touch Sensor¶
# Example configuration entry mpr121: id: mpr121_component address: 0x5A touch_debounce: 1 release_debounce: 1 touch_threshold: 10 release_threshold: 7 binary_sensor: - platform: mpr121 id: touch_key0 channel: 0 name: "Touch Key 0" touch_threshold: 12 release_threshold: 6
The configuration is made up of two parts: The central component, and individual Binary sensors per channel.
address (Optional, integer): The I²C address of the sensor. Defaults to
id (Optional, ID): Set the ID of this sensor.
touch_debounce (Optional, integer): The minimum length before a touch is recognized. Range is from 0 to 7. Defaults to 0.
release_debounce (Optional, integer): The minimum length that no touch is recognized before a release event is created. Range is from 0 to 7. Defaults to 0.
touch_threshold (Optional, integer): The touch threshold for all channels. This defines the sensitivity for touch detection and should be between 5 and 30 (lower = more sensitive). Defaults to 12. Typically the touch threshold is a little bigger than the release threshold.
release_threshold (Optional, integer): The release defines the sensitivity for touch detection and should be between 5 and 30. Defaults to 6.
mpr121 binary sensor allows you to use your MPR121 with ESPHome.
First, setup a Component/Hub and then use this binary sensor platform to create individual
binary sensors for each touch sensor.
name (Optional, string): The name for the binary sensor.
mpr121_id (Optional, ID): The ID of the MPR121 defined above. Useful for multiple MPR121’s on the I²C bus
id (Optional, ID): Manually specify the ID used for code generation.
channel (Required, integer): The channel number at the MPR121 the touchkey is connected to.
touch_threshold (Optional, integer): A per-channel override of the global touch_threshold value. If not specified, uses the global value.
release_threshold (Optional, integer): A per-channel override of the global release_threshold value. If not specified, uses the global value.
