Arduino Vacuum Gauge Sensor

Thakur definition pressure is defined as force per unit area that a fluid exerts on its surroundings.

Arduino vacuum gauge sensor.

The vacuum gauge outputs 0 10vdc. Initial build used a 10k pot in place of a vacuum gauge to make it simpler. That makes the math in the arduino sketch so easy. 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. 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. 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.

Force sensitive resistor thin film pressure sensor md30 60 0 30kg diameter 30mm resistance type thin film pressure sensor force sensing resistor. 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. 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.

I need a sensor that can be reasonably accurate down to roughly 28 inches mercury and would connect by a tube. 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. Ignore the humidity sensor that was for something else.

At 50 kpa that signal is about 4 95 vdc so it would be 90 mv per kpa. Sensore pressione md ps002 vacuum sensor absolute pressure senso for arduino. 3 0 out of 5.
