About Auntwhale Practical Temperature & Humidity Sensor

HTU21D is a high precision digital humidity and temperature sensor that is low cost, easy to use. The sensor is ideal for environmental sensing and data logging and is suitable for weather stations or humidity control systems. You only need two I2C communication lines, you can have a relative humidity reading and a very accurate temperature reading. Using this sensor requires only four pins to be connected. One for VCC, one for GND, and two for the I2C communication. The motherboard has a built-in 4.7k pull-up resistor for I2C communication.We accept custom orders. Please contact us with your ideas and we'll do our best to help you.Hope you have pleasure shopping time.Specification:Color: PurpleMaterial: resin + metalSize: length 1CM, width 1CM, thickness 0.2CMPower supply voltage: DC 1.5-3.6VHumidity measurement range: 0-100 percent RHTemperature measurement range: -40 degree -105 degreeMaximum power consumption: 2.7uWCommunication: I2CHumidity accuracy range (10 percent RH to 95 percent RH): ± 2 percent RHHumidity hysteresis: ± 1 percent RHMeasurement time: 50msDrift: -0.5 percent RH / yearResponse time: 5 secondsFunction: HTU21D is a high precision digital humidity and temperature sensor that is low cost, easy to use.
