การใช้งาน SHT10 temperature / humidity sensors

SHT10 digital humidity and temperature sensor is the low cost version of the reflow solderable humidity sensor series. The accuracies have been opened to a level that guarantees a very competitive price. The capacitive humidity sensor is available up to high volumes and as every other sensor type of the SHTxx family, it is fully calibrated and provides a digital output.

Features:

·         Interface Type: Serial (I2C non standard)

·         Humidity Ranger:0-100%RH

·         Tempereature ranger: -40-128.8 degree Celsius

·         Humidity accuracy:±4.5%RH

·         Temperature accuracy:±0.5 degree Celsius (25 degree Celsius)

·         Size: 32x17mm

·         Weight:5 gram
