The DHT11 uses a polymer humidity capacitor with NTC thermistor; the DHT22 replaces the thermistor with a DS18B20 1-wire thermometer. The DHT22 is also known as an AM2303. compatible: "aosong,dht" include: sensor-device.yaml properties: dio-gpios: type: phandle-array required: true description: | Pin on which sensor communication will be performed.
