The company’s most accurate ever pressure sensor, the 2SMPB-01-01 absolute pressure sensor from Omron Electronic Components can detect height differences of as little as 50cm and provide readings relative to a perfect vacuum to ±6Pa. The sensor is suited for measuring altitude, atmospheric pressure or water depth in wearable electronics, activity monitors, industrial and marine instruments and mobile phones and cameras.
Based on Omron’s MEMs technology, the 2SMPB-01-01 absolute pressure sensor provides an I2C output for easy integration into digital electronics and measures just 3.8x3.8x1mm. This is small enough to integrate into portable instruments.
Fully temperature compensated giving an absolute temperature accuracy of ±2°C, the sensor uses piezo resistance in a full bridge circuit to detect pressure. It features low power consumption of just 9µA (typical) simplifying 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.
The 2SMPB-01-01 absolute pressure sensor from Omron Electronic Components is supplied in 8-pin QFN package with surface mounting terminals.
