robert @ kandrsmith.org has a detailed article comparing the most common Humidity sensors. He writes: Previous experiments looked at comparing a set of six Aosong DHT22/AM2302 and compared the Aosong DHT22/AM2302 with the Aosong DHT11 and Sensirion SHT71. Here I have added five new devices meaning this test now covers most commonly available low-cost digital […]
