+
+The `stts22h` sensor platform allows you to use a STTS22H temperature sensor
+([datasheet](https://www.st.com/resource/en/datasheet/stts22h.pdf)) with ESPHome. This is a low-power,
+high-accuracy digital temperature sensor with ±0.5°C accuracy (typical at 25°C) and a temperature range
+from -40°C to +125°C.
+
+The [I²C Bus](/components/i2c) is required to be set up in your configuration for this sensor to work.

+```yaml
+# Example configuration entry
+sensor:
+  - platform: stts22h
+    name: "STTS22H Temperature"
+    address: 0x3C
+    update_interval: 60s
+```
+
+## Configuration variables
+
+- **i2c_id** (*Optional*, [ID](/guides/configuration-types#id)): Manually specify the ID of the
+  [I²C Bus](/components/i2c) if you want to use multiple I²C buses.
+
+- **address** (*Optional*, int): The I²C address of the sensor. Defaults to
+  `0x3C`.
+  The address is determined by the ADDR pin configuration on the sensor.
+  Possible addresses: `0x38`, `0x3C`, `0x3E`, `0x3F`.
+
+- **update_interval** (*Optional*, [Time](/guides/configuration-types#time)): The interval to check
+  the sensor. Defaults to `60s`.
+
+- All other options from [Sensor](/components/sensor).
