Description

Product information "SparkFun Qwiic - Humidity sensor breakout, SHTC3"

Want to log the climate in your greenhouse, create a humidor control system or track temperature and humidity data for a weather station project? The SparkFun SHTC3 Humidity Sensor could be the perfect option for you! The SHTC3 is an affordable, easy-to-use, highly accurate digital humidity and temperature sensor. The SHTC3 communicates via I2C. As you can see from the name, we've split the sensor's pins to Qwiic connectors so you can easily connect it to SparkFun's ever-growing Qwiic ecosystem.

Sensirion's SHTC3 digital humidity sensor builds on the success of the SHTC1 sensor, offering a wider supply voltage range (1.62V to 3.6V) and higher accuracy (±2% RH, ±0.2°C) than its predecessor, allowing for greater flexibility. You only need two wires for I2C communication and as a bonus you get relative humidity and very accurate temperature measurements!

Connecting is a breeze as the breakout board uses the Qwiic Connect system. The breakout board has built-in 2.2k? Pull-up resistors for I2C communication. If you connect several I2C devices to the same bus, you should deactivate these resistors.

Note: The I2C address of the SHTC3 is 0x70 and is hardware-defined. To address several SHTC3 sensors on one bus, a multiplexer/mux is required. Unfortunately, this is the same I2C address that our Qwiic Mux uses and this part is not compatible with the Qwiic Mux.

Features:
  • Uses I2C interface (Qwiic capable)
    • I2C address: 0x70
    • 2x Qwiic connections
  • Operating voltage range
    • 1.62V - 3.6 V
    • Typically 3.3V when using the Qwiic cable
  • Relative humidity
    • Operating range: 0% to 100%
    • Typical accuracy: ±2 %RH
    • Resolution: 0.01 %RH
  • Temperature
    • Operating range: -40°C to +125 °C
    • Typical accuracy: ±0.2 °C
    • Resolution: 0.01 °C
  • Typical current consumption (varies depending on mode)
