A new highly accurate absolute pressure sensor from Omron Electronic Components Europe can detect height differences of as little as 50cm. Based on Omron’s MEMS technology, the tiny sensor module can measure altitude, atmospheric pressure or water depth in wearable electronics, activity monitors, industrial and marine instruments and mobile phones and cameras.
The new Omron 2SMBP-01-01 absolute pressure sensor is the company’s most accurate ever pressure sensor, providing readings relative to a perfect vacuum to ± 6Pa. The module is just 3.8mm x 3.8mm x 1 mm maximum, small enough to integrate into portable instruments. It provides an I2C output for easy integration into digital electronics.
The sensor uses piezo resistance in a full bridge circuit to detect pressure, and is fully temperature compensated giving an absolute temperature accuracy of ± 2°C. The 2SMBP-01-01 offers the benefit of low power consumption of just 9 μA typical, further simplifying its integration into portable and other battery powered electronic systems.
The 2SMPB-01-01 can operate in three different power modes: standard, high accuracy and low power mode. Product is packaged in 8 pin QFN structure with surface mounting terminals.
