Returns Simplified.Looking to keep a log of the climate in your greenhouse, create a humidor control system or want to track temperature and humidity data for a weather station project? The SparkFun SHTC3 Humidity Sensor may be the perfect option for you! The SHTC3 is a low cost, easy-to-use, highly accurate digital humidity and temperature sensor. The SHTC3 communicates via I2C so, as you can tell by the name, we have broken out the pins on the sensor to Qwiic connectors so you can easily connect it to SparkFun’s ever-growing Qwiic Ecosystem.
The SHTC3 digital humidity sensor from Sensirion builds on the success of their SHTC1 sensor with a broader supply voltage range (1.62V to 3.6V) and higher accuracy (2% RH, 0.2C) than its predecessor, enabling greater flexibility. All you need are two lines for I2C communication, and youll have relative humidity readings and very accurate temperature readings as a bonus!
Hook up is a breeze as the breakout board is using the Qwiic connect system. The breakout board has built-in 2.2k pullup resistors for I2C communications. You may want to disable these resistors if youre hooking up multiple I2C devices on the same bus.
Note: The I2C address of the SHTC3 is 0x70 and is hardware defined. A multiplexer/Mux is required to communicate to multiple SHTC3 sensors on a single bus.
