The HTS221 sensor integrates a dedicated capacitive polymer sensing element for humidity and a band-gap sensor for temperature, coupled with a mixed-signal ASIC for signal conditioning and digitization. This architecture ensures stable, high-resolution measurements across a broad operating range from -40°C to +120°C.
Designed for low-power embedded systems, the sensor features selectable output data rates from 1 Hz to 12.5 Hz, allowing for power consumption optimization based on application requirements. Its fully calibrated digital output simplifies design-in, providing immediate access to accurate relative humidity and temperature data without additional signal processing.
