Temperature Humidity Sensor GY-213V-HTU21D HTU21D I2C Replace SHT21 SI7021 HDC1080 Module

The HTU21D is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems. All you need is two lines for I2C communication and you'll have relative humidity readings and very accurate temperature readings as a bonus!

There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC, one for GND, and two data lines for I2C communication. This breakout board has built in 4.7k pull up resistors for I2C communications. If you're hooking up multiple I2C devices on the same bus, you may want to disable these resistors.

Meanwhile HTU21D Switzerland can SHT20, SHT21 full compatibility can be achieved Pin to Pin Pin on hardware, without modifying the circuit board. Software programs and also Switzerland SHT20, SHT21 same can be achieved compatible replacement, without making any changes. Meanwhile HTU21D than Switzerland SHT20, SHT21 has a good price advantage, very cost-effective. HTU21D ultra-small size of the temperature and humidity digital output module is a good one by the famous French sensor manufacturer Humirel company introduced a performance products. Meanwhile, HTU21D has a significant advantage in terms of price, performance, power and so on.
