MPS20N0040D 40KPA AIR PRESSURE AMPLIFIER ADC
MPS20N0040D based 40kPa air pressure sensor module with onboard amplifier and ADC output for accurate gas and air pressure measurement.
The MPS20N0040D 40kPa Air Pressure Amplifier ADC Module is a high-precision pressure sensing solution designed for accurate measurement of air and non-corrosive gas pressure. Based on the MPS20N0040D piezoresistive pressure sensor, this module includes an onboard signal conditioning amplifier and ADC circuit, making it easy to interface with microcontrollers such as Arduino, PIC, AVR, ARM, and STM32.
With a pressure range of 0–40kPa, the module delivers stable, low-noise analog output suitable for applications like medical devices, weather monitoring, HVAC systems, industrial control, and air flow measurement. The compact PCB design, low power consumption, and high sensitivity make it ideal for both educational projects and professional embedded applications.
