The SHT21 from Sensirion is a high-precision, factory-calibrated digital sensor that combines relative humidity and temperature sensing in a single, compact DFN package. It utilizes a capacitive polymer sensing element for humidity and a band-gap sensor for temperature, delivering excellent long-term stability and fast response times.
Designed for seamless integration, its digital I2C output eliminates the need for signal conditioning, providing a calibrated, linearized digital signal directly to the host microcontroller. The robust construction ensures reliable performance across a broad spectrum of environmental monitoring, HVAC, and industrial process control applications.
