Function introduction

MSP20 Pressure Sensor module Principle: XGZP is a piezoresistive pressure sensor designed to be very sensitive to space, its core is silicon, using MEMS technology to design and manufacture piezoresistive pressure sensing molds.

A Wheatstone bridge structure is established by a spring diaphragm and four piezoelectric resistors integrated into the diaphragm. When the elastic diaphragm is under pressure, Wheatstone bridge will produce a linear voltage signal (mV) output, according to the collected voltage, the single chip computer can be converted into a pressure value.

Operating voltage: DC5.0V

Output signal: Analog signal 0-3.5V (the greater the voltage, the greater the pressure value)

Detection range: 0kpa-100kpa

Application: SCM control of blood pressure, tire pressure, air mattress, pneumatic equipment, Boyle experiment and other electronic design.

Dimensions: 30x19x1.6mm

Shipping list: Pressure Sensor module *1

Wiring: VCC: Connect DC5.0V power supply to the positive terminal (supply power to the sensor)

GND: connects to the negative terminal of the power supply

AO: analog signal output, connected to MCU ADC acquisition interface
