HTU21D is a cheap, easy to use, very accurate, digital hygrometer and thermometer.
This sensor is ideal for recording data of the environment and is ideal for weather stations or other control systems.
All you need are two wires for I2C communication and you have the value of relative humidity
and very accurate temperature readings as a bonus!
You only need four pins which must be connected to the microcontroller.
One for VCC, GND and one for two wire data line for I2C communication.
This board is fitted with 4.7 K pull-up resistors for I2C communication.
It's summer, you're sweating, your hair is all frizzy and all you really want to
to know is why the weatherman said this morning that today will be a maximum relative humidity of
the perfect level of humidity 52%, even though it feels more like 77%.
Use accurate smart sensor HTU21D-F for the measurement of temperature and humidity. Prove weathermen, they don't have the exact dates.
This I2C digital hygrometer has the perfect accuracy of ± 2% in the range of 5% to 95% RH
Operation outside this range is possible, but it is necessary to count with less accuracy.
The temperature of this module is measured with an accuracy of ± 1 ° C in a wide range from -30 ~ 90 °
The integrated stabilizer to 3.3 V I2C level is a matter of course. It will allow You to securely use the module with any microcontroller with 3.3 or 5V logic.
Each module is supplied including dupont pins. This accessory will help you in the event that you want the module to connect using wires. For this you will need a soldering iron, but this is relatively a simple act and takes just a few minutes, even novice.
In conclusion, we present the very small dimensions of the module: 1.2x1cm

Included
1pc HTU21D I2C Temperature Sensor and Humidity
