SENSHTC3
Overview
The SHTC3 is a digital humidity and temperature sensor designed specifically for high-volume, battery-powered consumer electronics. It utilizes Sensirion CMOSens technology to integrate a sensing element and digital interface on a single chip, offering a wide supply voltage range of 1.62V to 3.6V. This sensor is optimized for ultra-low power consumption, featuring a sleep current of only 0.6 uA.
Why Choose This Part
The SHTC3 excels in power efficiency, consuming only 0.27 to 0.9 mA during active measurements and maintaining an ultra-low idle state. Its small 4-WDFN footprint and standard I2C interface allow for easy integration into space-constrained PCB designs. With a specified accuracy of +/-2% RH and a wide operating temperature range from -40 to 125 degrees Celsius, it provides reliable performance across diverse environments.
Applications
Key Specifications
Getting Started
To evaluate the sensor, engineers can use the Sensirion SEK-SHTC3 evaluation kit or integrate the chip onto a custom PCB using the 4-WDFN land pattern. Communication is handled via a standard I2C bus; Sensirion provides C-based driver libraries and Arduino-compatible code to simplify the implementation of measurement commands and 16-bit data conversion. Ensure proper PCB thermal isolation and ventilation around the sensor aperture for accurate ambient readings.
