HTU21D Temperature & Humidity Sensor Module

Product Features
The next generation HTU21D temperature and humidity sensor sets new standards in terms of size and intelligence: a double row, flattened, leadless DFN package for reflow with a 3x3mm bottom height and a 1.1mm height.
Sensor output calibration digital signal, standard I2C format.
Diverse output power, wide operating voltage range, with high temperature accuracy and humidity accuracy.
HTU21 series modules are designed for low power consumption and small volume applications. They are of good quality, fast response, strong anti-interference ability and high cost performance. Small size (3x3mm), low power consumption.
At the same time, the HTU21D is fully compatible with the SHT20 and SHT21 in Switzerland, with pin-to-pin implementation on the hardware pins without modification of the board.
product description
Description:
The HTU21D is a low cost, easy to use, highly accurate digital humidity and temperature sensor. The sensor is ideal for environmental sensing and data logging and is ideal for weather stations or moisture control systems. All you need is two lines for I2C communication, and you will have a relative humidity reading and a very accurate temperature reading as a bonus!
Only four pins need to be connected to use the sensor in the project. One for VCC, one for GND, and two data lines for I2C communication. The breakout board has built-in 4.7k pull-up resistor for I2C communication. If you are connecting multiple I2C devices on the same bus, you may need to disable these resistors.
