Extension board offers a complete sensor system on a single chip

Mouser now stocks the SHTW2 Xplained Pro Dual Humidity and Temperature Extension Board from Sensirion. The new extension board for Microchip’s SAMD20 Xplained Pro Board features two Sensirion SHTW2 humidity and temperature sensors and acts as an intelligent circuit, enabling developers to incorporate on/off body detection for improved battery management. The board is based on the second-generation digital humidity and temperature sensor in a tiny flip chip package. The device offers a complete sensor system on a single chip, integrating a capacitive humidity sensor, a band-gap temperature sensor, analog and digital signal processing, ADC, calibration data memory, and a digital communication interface that supports I2C fast mode. With the two onboard 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.
