MEMS atmospheric pressure sensor offers 0.1% accuracy, in distribution

Mouser Electronics has the ZPA Series MEMS pressure sensor from Murata, a 2.3 × 2.6 mm micro-electro-mechanical systems (MEMS) sensor that provides highly accurate pressure readings from 300 to 1,100 hPa, down to 0.016 Pa resolution.

The sensor employs capacitive sensing technology, which enables its ±1.0 hPa absolute accuracy across a wide temperature range (-10 to +65C; P=800 to 1,100 hPa). This capacitive sensing technology enables a low typical noise level of 1.1 PaRMS and current consumption of 6.3 µA at 0.16-second conversion time.

The ZPA Series MEMS pressure sensor features SPI and I ²C communication interfaces, and is designed for applications that demand high accuracy and low current consumption, including medical equipment, elevator equipment, indoor navigation, and weather monitoring.
