Arduino Vacuum Gauge Sensor

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

Arduino vacuum gauge sensor.

At 50 kpa that signal is about 4 95 vdc so it would be 90 mv per kpa. That makes the math in the arduino sketch so easy. Thakur definition pressure is defined as force per unit area that a fluid exerts on its surroundings. Also the vacuum version of the sensor is mpxv5050vc6t1 and is made by nxp usa for about 10 each.

The vacuum gauge outputs 0 10vdc. This had to be changed to a 0 5vdc range using a potential divider so it was compatible with the arduino. With 0 kpa vacuum on th port the signal out to the arduino would be about 4 96 vdc. Link to my website for diagrams code and resources to recreate my experiments.

I can control the vacuum pumps easily enough but it is hard to find a vacuum sensor for the arduino. It has a measuring range of 2 9 psi to 36 3 psi absolute. 3 0 out of 5. The oled screen.

Ignore the humidity sensor that was for something else. Sensore pressione md ps002 vacuum sensor pressure sensor for arduino. Initial build used a 10k pot in place of a vacuum gauge to make it simpler. Sensore pressione md ps002 vacuum sensor absolute pressure senso for arduino.

I need a sensor that can be reasonably accurate down to roughly 28 inches mercury and would connect by a tube.
