Enviro pHAT
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 Variables
List of readings to monitor.
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)
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
Give the values friendly names & icons
Add something like the following to your customize section:
# Example configuration.yaml entry
customize:
sensor.accelerometer_z:
icon: mdi:airplane-landing
friendly_name: "Acc Z"
sensor.magnetometer_x:
icon: mdi:arrow-up-bold-hexagon-outline
friendly_name: "Magnetic X"
sensor.pressure:
icon: mdi:weight
friendly_name: "Pressure"
Create groups
# Example configuration.yaml entry
group:
enviro_phat_voltages:
name: Enviro pHAT Voltages`
entities:
- sensor.voltage_0
- sensor.voltage_1
- sensor.voltage_2
- sensor.voltage_3
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
