Tailored for embedding into compact smartphones and other mobile devices, the HSHCAL Series capacitive digital humidity sensor delivers a digital output and boasts the market’s smallest mounting area: 2 mm x 2 mm. The components employ a proprietary sensing film that ensures reliable linearity over a relative-humidity range from 0 to 100%. Additionally, a temperature-output function enables temperature compensation within the sensor device. Specifications include an operating temperature range -20°C to +85°C, a supply voltage 1.71V to 1.89V, temperature sensitivity of 50 LSB/°C, and an accuracy of ±1.5% RH at 25°C/50% RH.
