-
-This integration is deprecated and will be removed in Home Assistant Core 2022.4.
-
-For more information see: [Architectural Decision Record 0019](https://github.com/home-assistant/architecture/blob/master/adr/0019-GPIO.md).
-
-</div>
-
-The `htu21d` sensor platform allows you to read the temperature and humidity from a [HTU21D sensor](https://cdn-shop.adafruit.com/datasheets/1899_HTU21D.pdf) connected via [I2c](https://en.wikipedia.org/wiki/I²C) bus (SDA, SCL pins).
-
-Tested devices:
-
-- [Raspberry Pi](https://www.raspberrypi.org/)
-
-## Configuration
-
-To use your HTU21D sensor in your installation, add the following to your `configuration.yaml` file:
-
-```yaml
-# Example configuration.yaml entry
-sensor:
-  - platform: htu21d
-```
-
-{% configuration %}
-name:
-  description: The name of the sensor.
-  required: false
-  default: i2c_bus
-  type: string
-i2c_bus:
-  description: I2c bus where the sensor is.
-  required: false
-  default: 1 (for Raspberry Pi 2 and 3)
-  type: integer
-{% endconfiguration %}
-
-## Customizing the sensor data
-
-Give the values friendly names and icons, add the following to your `customize:` section.
-
-```yaml
-# Example configuration.yaml entry
-customize:
-  sensor.htu21d_sensor_temperature:
-    icon: mdi:thermometer
-    friendly_name: "Temperature"
-  sensor.htu21d_sensor_humidity:
-    icon: mdi:weather-rainy
-    friendly_name: "Humidity"
-```
-
-To create a group, add the following to your `groups` section.
-
-```yaml
-# Example configuration.yaml entry
-group:
-  ambient_sensor:
-    name: HTU21D Environment sensor
-    entities:
-      - sensor.htu21d_sensor_temperature
-      - sensor.htu21d_sensor_humidity
-```
-
-## Directions for installing smbus support on Raspberry Pi
-
-Enable I2c interface with the Raspberry Pi configuration utility:
-
-```bash
-# pi user environment: Enable i2c interface
-$ sudo raspi-config
-```
-
-Select `Interfacing options->I2C` choose `<Yes>` and hit `Enter`, then go to `Finish` and you'll be prompted to reboot.
-
-Install dependencies for use the `smbus-cffi` module and enable your `homeassistant` user to join the _i2c_ group:
-
-```bash
-# pi user environment: Install i2c dependencies and utilities
-$ sudo apt-get install build-essential libi2c-dev i2c-tools python-dev libffi-dev
-
-# pi user environment: Add homeassistant user to the i2c group
-$ sudo addgroup homeassistant i2c
-
-# pi user environment: Reboot Raspberry Pi to apply changes
-$ sudo reboot
-```
-
-### Check the i2c address of the sensor
-
-After installing `i2c-tools`, a new utility is available to scan the addresses of the connected sensors:
-
-```bash
-/usr/sbin/i2cdetect -y 1
-```
-
-It will output a table like this:
-
-```text
-     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
-00:          -- -- -- -- -- -- -- -- -- -- -- -- --
-10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-20: -- -- -- 23 -- -- -- -- -- -- -- -- -- -- -- --
-30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-40: 40 -- -- -- -- -- UU -- -- -- -- -- -- -- -- --
-50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-70: -- -- -- -- -- -- -- 77
-```
-
-So you can see the sensor is present at the **0x40** address (there are more i2c sensors in that Raspberry Pi).
