Sensirion’s SHTC3 digital humidity sensor builds on the success of their SHTC1 sensor. The SHTC3 has a broader supply voltage range (1.62V to 3.6V) and higher accuracy (±2% RH, ±0.2°C) than its predecessor, enabling greater flexibility.
The SHTC3 is 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 build a weather stations or humidor control system. All you need are two lines for I2C communication, and you’ll have relative humidity readings and very accurate temperature readings as a bonus!
Hook up is a breeze with as the breakout board is using the Qwiic connect system. The breakout board has built-in 2.2kΩ pullup resistors for I2C communications. If you’re hooking up multiple I2C devices on the same bus, you may want to disable these resistors.
Based on 1 ratings:
Used this to evaluate SHTC3 at work. Easy to setup and get working with the arduino driver and example. Practical with the Qwiic to add other I2C units and the breakout was used to scope the I2C pins.
