Arduino Vacuum Gauge Sensor

The vacuum gauge outputs 0 10vdc.

Arduino vacuum gauge sensor.

I can control the vacuum pumps easily enough but it is hard to find a vacuum sensor for the arduino. The oled screen. Ignore the humidity sensor that was for something else. I need a sensor that can be reasonably accurate down to roughly 28 inches mercury and would connect by a tube.

That makes the math in the arduino sketch so easy. Sensore pressione md ps002 vacuum sensor pressure sensor for arduino. 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. 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. It outputs a temperature compensated analog voltage that is proportional to an absolute pressure. May 13 2016 arduino tutorials air arduino code measurement meter mpx5010dp pressure sensor manoj r. It has a measuring range of 2 9 psi to 36 3 psi absolute.

At 50 kpa that signal is about 4 95 vdc so it would be 90 mv per kpa. Thakur definition pressure is defined as force per unit area that a fluid exerts on its surroundings. Force sensitive resistor thin film pressure sensor md30 60 0 30kg diameter 30mm resistance type thin film pressure sensor force sensing resistor. The digital vacuum gauge is based on the mpxh6250a pressure sensor by freescale.

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. Link to my website for diagrams code and resources to recreate my experiments. 3 0 out of 5.
