AHT10 is a new generation of temperature and humidity sensor, outputs calibrated digital signals in standard I2C format. Temperature accuracy: ±0.3 °C. Humidity accuracy: ±2%. Working voltage: 1.8-6.0 V. Module size: 16x11 mm. Headers are included, but not soldered.
Simple temperature and humidity sensor module with digital output, operating voltage 3.3-5V, humidity measurement range 20- 95% (+/-5%), temperature range 0-50°C(+/-2°C).
The AHT20 is a nice but inexpensive temperature and humidity sensor from the same folks that brought us the DHT22. You can take sensor readings as often as you like, and it uses standard I2C so its super easy to use with any Arduino or Linux/Raspberry Pi board.
