HTU21D Humidity and Temperature Sensor Breakout
This SKU 384251 is available in DXSOUL with Free Expedited delivery. DXSOUL: 901384251
Description:

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.

Uses the I2C interface

Typical humidity accuracy of ±2%

Typical temperature accuracy of ±0.3C

Operates from 0 to 100% humidity but this sensor isn’t recommended for harsh environments where it could come in contact with water (such as rain).

3.3V sensor - use inline logic level converters or 10k resistors to limit 5V signals

Here’s the datasheet

Only one HTU21D sensor can reside on the I2C bus at a time

This sensor is ideal for environmental sensing and data logging. Perfect for a weather station or humidor control system. It is a very good replacement for digital humidity sensors such as the SHT15, SHT21, SHT25, HIH-4030, HIH6130 and capacitive humidity sensors such as the HH10D.
