SHT-40 Temperature & Humidity Sensor - Qwiic Ready

Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And finally, we have some that have a true I2C interface for easy reading. The SHT40 has an excellent ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2 °C typical accuracy from 0 to 75 °C.



Unlike some earlier SHT sensors, this sensor has a true I2C interface for easy interfacing with only two wires (plus power and ground). Thanks to the voltage regulator and level shifting circuitry Adafruit have included on the breakout it is also 3V or 5V compliant, so you can power and communicate with it using any microcontroller or microcomputer.
