SENSIRION SHT21TR04KS Humidity and Temperature Sensor
The SHT21 is a surface-mount temperature and humidity sensor from Sensirion, widely regarded as an industry standard due to its compact form factor and intelligent design. Encased in a reflow-solderable 3x3mm DFN package with a height of 1.1mm, it provides calibrated, linearized digital signals via I²C interface. The sensor integrates a capacitive humidity sensor, a bandgap temperature sensor, and specialized analog and digital circuitry on a single CMOSens® chip, offering high accuracy, stability, and low power consumption. Key features include a ±2% RH accuracy, digital output, low energy consumption of about 3.2µW at 8-bit resolution with one measurement per second, and a humidity response time of approximately 8 seconds. The device operates within a supply voltage range of 2.1V to 3.6V and is suitable for sensing and instrumentation applications. It is sensitive to electrostatic discharge (ESD), so proper handling precautions are advised.
