Waterproof digital sensor measures air and water pressure

Alps Alpine has started mass-producing the HSPPAD143A waterproof digital pressure sensor for wide-ranging applications in wearable devices and IoT equipment such as flow meters for essential utilities.

The sensor offers an expanded pressure measurement range of 300 to 2100hPa from a water-resistant design. This means it works in both low-pressure environments at altitudes up to 9,000 meters and high-pressure conditions down to 10 meters underwater, allowing measurement in both open air and water with a single sensor. The HSPPAD143A also houses a dedicated, fully customized application-specific integrated circuit (ASIC), drawing only 1.8µA in low power mode.
