HiLetgo HTU21D Temperature Humidity Sensor Breakout Module I2C IIC 1.5V-3.6V Replace SHT15 Compatible to SHT20 SHT21


Brand: HiLetgo

Color: Red


  • The new generation of HTU21D temperature and humidity sensors has set new standards in terms of size and intelligence: it embeds a double row, flat, leadless DFN package for reflow, with a 3x3mm bottom surface and 1.1mm height.
  • Sensor output calibrated digital signal, standard I2C format.
  • Diversified output, wide operating voltage range, also it have high temperature accuracy and humidity accuracy.
  • Designed for low power and small volume applications, the HTU21 Series modules are characterized by good quality, fast response, strong anti-interference ability, and high cost performance. The tiny volume (3x3mm), low power consumption.
  • At the same time, HTU21D can be fully compatible with SHT20 and SHT21 in Switzerland, Pin to Pin can be realized on hardware pins, without modifying the circuit board.

Details: 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. Specification: Supply voltage: 1.5V-3.6 Humidity measuring range: 0-100% RH Temperature measuring range: -40 ℃—105℃ Maximum power consumption: 2.7uW Communication: I2C Humidity accuracy range (10% RH to 95% RH): HTU21D ± 2% RH Humidity Hysteresis: ± 1% RH Measurement time: 50ms In drift: -0.5% RH / year Response time: 5 s Package Inlcuded: 1*HTU21D Temperature Humidity Sensor Breakout Module
