HTU21D TEMPERATURE & HUMIDITY SENSOR

DESCRIPTION:

The HTU21D is a low-cost, easy to use, highly accurate, digital humidity sensor. All you need is two lines for I²C communication and you’ll have relative humidity readings such as “45.2%” or “23.1%” 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.

FEATURES:

• Voltage Supply: DC 1.5V—3.6V
• Humidity Range：0—100%RH
• Temperature Range:-40℃—105℃
• Uses the I²C interface
• Typical humidity accuracy of ±2%
• Typical temperature accuracy of ±0.3C
• Time Response: 50ms
