Arduino Vacuum Gauge Sensor

It outputs a temperature compensated analog voltage that is proportional to an absolute pressure.

Arduino vacuum gauge sensor.

Link to my website for diagrams code and resources to recreate my experiments. The oled screen. Initial build used a 10k pot in place of a vacuum gauge to make it simpler. Also the vacuum version of the sensor is mpxv5050vc6t1 and is made by nxp usa for about 10 each.

At one point in the process it needs to determine the level of vacuum in a chamber and adjust it to within a range of values. Sensore pressione md ps002 vacuum sensor absolute pressure senso for arduino. Thakur definition pressure is defined as force per unit area that a fluid exerts on its surroundings. It has a measuring range of 2 9 psi to 36 3 psi absolute.

This had to be changed to a 0 5vdc range using a potential divider so it was compatible with the arduino. The digital vacuum gauge is based on the mpxh6250a pressure sensor by freescale. The vacuum gauge outputs 0 10vdc. Force sensitive resistor thin film pressure sensor md30 60 0 30kg diameter 30mm resistance type thin film pressure sensor force sensing resistor.

Ignore the humidity sensor that was for something else. Diymall bme280 humidity temperature sensor barometric pressure sensor module with iic i2c for arduino gy bme280 5v pack of 1pc 4 3 out of 5 stars 68 9 49 9. With 0 kpa vacuum on th port the signal out to the arduino would be about 4 96 vdc. May 13 2016 arduino tutorials air arduino code measurement meter mpx5010dp pressure sensor manoj r.

That makes the math in the arduino sketch so easy. At 50 kpa that signal is about 4 95 vdc so it would be 90 mv per kpa. Sensore pressione md ps002 vacuum sensor pressure sensor for arduino.
