HTU21 is integrating circuit temperature and humidity measurements with high resolution and transmission over the I2C bus. Measurement time is at 14-bit resolution (0.01 ° C) typically 44ms. When comparing with the known circuit DS18B20 that needs to 12 bit measurements 750ms, so it's very fast processing, suitable for frequent monitoring changes in these variables.
HTU 21 Circuit measuring temperature and ambient humidity Measurement range Humidity: 0% ~ 100% RH Temperature measurement range: -40 ° C ~ 125 ° C Power consumption: 0.15uA Interface: I2C (SDA, SCL) Temperature resolution: 0.01 ° C (14 bit) 0.04 ° C (12bit) Humidity Resolution: 0.04% RH / ° C 0.02 Time temperature measurement: typically 44ms (14bit) The period of humidity measurement: typically 12ms (12bit) Accuracy: ± 2% RH / ± 0.3 ° C Working voltage: 1.5V ~ 3.6V DC Board dimensions: 13 mm x 10 mm
