The `envirophat` sensor platform allows you to display information collected by an [Enviro pHAT](https://shop.pimoroni.com/products/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:
```yaml
# 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](https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-enviro-phat) regarding how to make a voltage divider
### {% linkable_title Give the values friendly names & icons %}
Add something like the following to your [customize section](/docs/configuration/customizing-devices/):
```yaml
# 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
```yaml
# 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](https://www.raspberrypi.org/documentation/configuration/device-tree.md) in the Raspberry Pi documentation):
```
dtparam=i2c_arm=on
```
