Compact Design: The HTU21 I2C Humidity and Temperature Sensor is a monolithic CMOS IC that integrates humidity and temperature sensor elements, analog-to-digital converters, signal processing, calibration data and I2C interface.
With this sensor you can measure temperature and humidity with a very high level of accuracy. The data can be transferred directly via I2C protocol, e.g. can be read out with A-rduino.
Wide compatibility: The GY 21 sensor is suitable for: Automotive (Defogging, HVAC), Home Appliances, Medical, Printers, perfect for weather stations or humidor control systems. Asset and goods tracking.Mobile phones and tablets.
Features: Operating voltage: 3V – 5V DC. Current consumption: 150mA.
Measuring range, humidity: 0% – 80%. Measuring range Temp.: -10° – 85° C.
