Arduino Vacuum Gauge Sensor

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.

Arduino vacuum gauge sensor.

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. The digital vacuum gauge is based on the mpxh6250a pressure sensor by freescale. Also the vacuum version of the sensor is mpxv5050vc6t1 and is made by nxp usa for about 10 each. Thakur definition pressure is defined as force per unit area that a fluid exerts on its surroundings.

3 0 out of 5. It has a measuring range of 2 9 psi to 36 3 psi absolute. Ignore the humidity sensor that was for something else. The oled screen.

I can control the vacuum pumps easily enough but it is hard to find a vacuum sensor for the arduino. It outputs a temperature compensated analog voltage that is proportional to an absolute pressure. At 50 kpa that signal is about 4 95 vdc so it would be 90 mv per kpa. This had to be changed to a 0 5vdc range using a potential divider so it was compatible with the arduino.

I need a sensor that can be reasonably accurate down to roughly 28 inches mercury and would connect by a tube. The vacuum gauge outputs 0 10vdc. With 0 kpa vacuum on th port the signal out to the arduino would be about 4 96 vdc. Sensore pressione md ps002 vacuum sensor pressure sensor for arduino.
