Mitsumi EASR940C04A-B1 Development Kit
Mitsumi EASR940C04A-B1 Development Kit is an evaluation platform for the MMR940C04A digital-output differential pressure sensor. The MMR940C04A sensor provides factory-calibrated, temperature-compensated pressure measurements. The sensor also supports a differential pressure range of ±40cmH2O (±3.922kPa) and delivers high-resolution digital output. A built-in low-pass filter helps reduce noise and improve measurement stability. The EASR940C04A-B1 kit includes an MMR940C04A I2C sensor board and a Sensor Shield I2C cable for quick connection and testing. This kit enables rapid prototyping and evaluation of pressure-sensing applications and is designed for use with the Mitsumi Sensor Shield Kit Ver. 2 and compatible Arduino® boards.
