The envirophat
sensor platform allows you to display information collected by an Enviro pHAT add-on board for the Raspberry Pi. The board features a wide range of sensors, such as:
- BMP280 temperature/pressure sensor
- TCS3472 light and RGB color sensor with two LEDs for illumination
- LSM303D accelerometer/magnetometer sensor
- ADS1015 4-channel 3.3v, analog to digital sensor (ADC)
To add this platform to your installation, add the following to your configuration.yaml
file:
# Example configuration.yaml entry,
# which is equivalent to the default setup
sensor:
- platform: envirophat
use_led: false
display_options:
- temperature
- pressure
- light
- light_red
- light_green
- light_blue
- accelerometer_x
- accelerometer_y
- accelerometer_z
- magnetometer_x
- magnetometer_y
- magnetometer_z
- voltage_0
- voltage_1
- voltage_2
- voltage_3
{% configuration %} display_options: description: List of readings to monitor. required: false default: All the conditions type: list keys: temperature: description: Ambient temperature in Celsius. Since the sensor is close to the Raspberry Pi, that might affect the accuracy of the reading (ie. the Pi might heat up the sensor) pressure: description: Atmospheric pressure in hPa. light: description: Ambient light, as an integer in the 0-65535 range. light_red: description: Red color reading scaled to the ambient light, as an integer in the 0-255 range. light_green: description: Green color reading scaled to the ambient light, as an integer in the 0-255 range. light_blue: description: Blue color reading scaled to the ambient light, as an integer in the 0-255 range. accelerometer_x: description: Accelerometer reading in units of G, along the X axis. accelerometer_y: description: Accelerometer reading in units of G, along the Y axis. accelerometer_z: description: Accelerometer reading in units of G, along the Z axis. magnetometer_x: description: Magnetometer reading, the X component of the raw vector. magnetometer_y: description: Magnetometer reading, the y component of the raw vector. magnetometer_z: description: Magnetometer reading, the z component of the raw vector. voltage_0: description: Voltage reading on Analog In 0 in units of V. voltage_1: description: Voltage reading on Analog In 1 in units of V. voltage_2: description: Voltage reading on Analog In 2 in units of V. voltage_3: description: Voltage reading on Analog In 3 in units of V. use_led: description: Declaring that the on-board LEDs are not used for the color measurements thus these readings are based on the ambient light. If the value is set to True, the on-board LEDs will blink whenever a reading is taken. required: false default: false type: boolean {% endconfiguration %}
{% linkable_title Notes %}
X, Y, Z axes
- X is parallel with the long edge of the board
- Y is parallel with the short edge of the board
- Z is perpendicular to the board
Voltages
- voltage readings are done in the 0-3.3V range, please do not connect higher voltages than that! See the Enviro pHAT's getting started guide regarding how to make a voltage divider
{% linkable_title Give the values friendly names & icons %}
Add something like the following to your customize section:

Enabling the required i2c-1
device
Since the Enviro pHAT communicates over I2C, you might also need to make sure that the I2C devices are enabled, by adding or uncommenting the following line in /boot/config.txt
(see the DT Parameters section in the Raspberry Pi documentation):
dtparam=i2c_arm=on
