MD-PS002 Vacuum Pressure Sensor Module

The MD-PS002 Vacuum Pressure Sensor Module is a compact, high-accuracy pressure sensor designed to measure vacuum and low positive pressure levels in a variety of industrial and electronic applications. Operating at 5V DC or 1mA constant current, it uses a resistor bridge configuration to deliver precise analog output readings. With a pressure measurement range from -100kPa to +50kPa (up to 150kPa absolute), this sensor is ideal for monitoring air pressure, vacuum systems, and fluid flow. Its small 6.8mm × 6.8mm × 4.6mm footprint makes it suitable for integration in portable and embedded systems. The MD-PS002 is commonly used in automotive MAP sensors, medical devices, and industrial automation, ensuring accurate and consistent performance across a wide temperature range (-40°C to +85°C). Its reliability and versatility make it an essential component for real-time pressure measurement in smart, IoT-enabled projects. Featured By RoboticsBD.

How to Use the MD-PS002 Vacuum Pressure Sensor Module

1. Power the Sensor

   • Connect VCC to 5V and GND to ground.
   • If using a constant current mode, set it to 1mA.

2. Connect Output to Microcontroller

   • The analog output provides a voltage proportional to the measured pressure.
   • Connect the output pin to an ADC (Analog-to-Digital Converter) input of a microcontroller (such as Arduino, ESP32, or STM32).

3. Read the Pressure Data

   • Convert the analog voltage reading to pressure values using a pre-defined formula.
   • Use this data for monitoring and control applications.
