+
+The ``am2320`` Temperature+Humidity sensor allows you to use your am2320
+(`datasheet <https://akizukidenshi.com/download/ds/aosong/AM2320.pdf>`__) i2c-based sensor with ESPHome.

+
+    Logs might include some warnings about receiving a NACK from the sensor.
+    This is due to a wake call to the sensor which the sensor never acknowledges by design.

+    # Example configuration entry
+    sensor:
+      - platform: am2320
+        temperature:
+          name: "Living Room Temperature"
+        humidity:
+          name: "Living Room Humidity"
+        update_interval: 60s
+
+Configuration variables:
