Humidity extension board enhances battery management

The board is based on the SHTW2, Sensirion’s second-generation digital humidity and temperature sensor in a tiny flip chip package.

The SHTW2 offers a complete sensor system on a single chip, integrating a capacitive humidity sensor, a band-gap temperature sensor, analogue and digital signal processing, analogue-to-digital converter (ADC), calibration data memory, and a digital communication interface that supports I²C fast mode.

With the two onboard SHTW2 sensors, developers can create designs with on/off body detection, which detects whether a device is worn on a person’s body to supply power.

This results in smarter battery management that corresponds to individual user’s needs in battery-driven devices such as headphones, fitness trackers, smart medical devices, and VR goggles.
