HDC1100-01P

Encoders, Decoders, Converters Overview

The HDC1100-01P is a digital relative humidity and temperature sensor manufactured by Texas Instruments, housed in a WSON package. It integrates capacitive sensing elements for humidity and a bandgap sensor for temperature on a single silicon die. The device operates with a supply voltage range of 2.97 V to 3.63 V. Key electrical parameters include a relative humidity accuracy of ±3% RH (maximum) at 25°C and a temperature accuracy of ±0.4°C (maximum). The humidity sensor features a typical capacitance of 180 pF. The unit communicates via a standard I²C interface with support for multiple slave addresses.
