    About this item

  • 【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.
  • 【Convenience】 All you need is two lines for I2C communication and you’ll have relative humidity readings and very accurate temperature readings. 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.
  • 【Specification】Power supply voltage: 1.5V-3.6. Humidity measurement range: 0-100%RH. Temperature measurement range :-40°C -105 °C. Power consumption :2.7uW. Communication mode :I2C. Humidity accuracy range (10%RH to 95%RH) :HTU21D±2%RH. Humidity lag: ±1%RH. Measurement time: 50ms. Annual drift: -0.5%RH/year. Response time: 5 s.
  • 【Compatibility & Comparison】HTU21D can be fully compatible with the Swiss SHT20 and SHT21, and the hardware Pin can be Pin to Pin without modifying the circuit board. The software program is also the same as the Swiss SHT20 and SHT21, which can achieve compatible replacement without making any modifications. At the same time, HTU21D has a good price advantage compared with Swiss SHT20 and SHT21.
