HDC1100-05P

Encoders, Decoders, Converters Overview

The HDC1100-05P is a digital humidity and temperature sensor manufactured by SMSC, designed for precise environmental monitoring. It integrates high-performance capacitive polymer sensing elements with CMOS signal conditioning circuitry on a single die. The device provides calibrated digital outputs for both relative humidity and temperature measurements via an I2C-compatible interface. Key electrical parameters include a relative humidity accuracy of ±3% RH (typical) over the operating range and a temperature accuracy of ±0.4°C (typical). The unit operates within a supply voltage range of 2.7V to 5.5V and features low power consumption modes suitable for battery-operated applications. It is housed in a compact surface-mount package.
