SparkFun Qwiic SHTC3 Humidity & Temperature Sensor Board

The SparkFun Qwiic SHTC3 Humidity & Temperature Sensor Board is a cost-effective and efficient solution for highly accurate digital humidity and temperature measurements. Built around the advanced SHTC3 sensor, this breakout board is ideal for climate control systems, weather station projects, and other environmental monitoring applications.

The board features dual Qwiic connectors, enabling rapid prototyping as part of the Qwiic Connect System. With built-in 2.2kΩ pullup resistors for I2C communication, setup is streamlined whether using Qwiic connectors or standard I2C pins. Designed for reliability, it operates over a broad humidity range (0% to 100%) and temperature range (-40°C to +125°C).

Key Features

• High Accuracy: ±2% RH for humidity and ±0.2°C for temperature readings.
• Dual Connectivity: Supports both Qwiic and I2C interfaces.
• Compact Design: 25.4mm x 25.4mm footprint for easy integration into projects.
• Low-Voltage Operation: Functions from 1.62V to 3.6V (3.3V via Qwiic).

Note: The I2C address is hardware-defined as 0x70, so a multiplexer is required to connect multiple SHTC3 sensors to the same bus (incompatible with Qwiic Mux due to overlapping addresses).
