Since the DHT22 has been discontinued, this sensor will be EOL soon. We strongly recommend you use the upgraded DHT20 sensor, that is Grove - Temperature & Humidity Sensor V2.0 (DHT20)
- High temperature and humidity measurement accuracy
- Humidity: 0 to 99.9 %RH with ±2% accuracy
- Temperature: -40 to 80℃ with ±0.5℃ accuracy
- Wide range of temperature and humidity measurement
- Ultra-low power consumption
- 20-meter signal transmission distance
- Factory calibrated, easy to use
DescriptionGrove - DHT22 is a high accuracy temperature and humidity sensor based on the DHT22 module (also known as AM2302 or RHT03). High-cost performance and high precision make it ideal for temperature and humidity monitoring of Arduino and Raspberry Pi, you can also use it to make a thermometer and hygrometer.
DHT22 and DHT11 are both excellent temperature and humidity sensors and they are widely used in Arduino and Raspberry Pi projects. However, from the comparison, the DHT22 outshines the DHT11 in every aspect from temperature range, temperature accuracy, humidity range to humidity accuracy. The only downside of the DHT22 is of course the slightly higher price but you are paying for the better specs.
So if you want a sensor with a wider range and accuracy, go for the DHT22. If not, the DHT11 should work fine for your projects as well.
All in all, DHT22 is an excellent low-cost temperature and humidity module, so we made this DHT22 breakout board with Grove connector. Now it even becomes more convenient to use. Just plug and play with your Seeeduino or Grove compatible shield. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs.
