Arduino Vacuum Gauge Sensor

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

Arduino vacuum gauge sensor.

Force sensitive resistor thin film pressure sensor md30 60 0 30kg diameter 30mm resistance type thin film pressure sensor force sensing resistor. Thakur definition pressure is defined as force per unit area that a fluid exerts on its surroundings. This had to be changed to a 0 5vdc range using a potential divider so it was compatible with the arduino. Sensore pressione md ps002 vacuum sensor absolute pressure senso for arduino.

May 13 2016 arduino tutorials air arduino code measurement meter mpx5010dp pressure sensor manoj r. Also the vacuum version of the sensor is mpxv5050vc6t1 and is made by nxp usa for about 10 each. The digital vacuum gauge is based on the mpxh6250a pressure sensor by freescale. I can control the vacuum pumps easily enough but it is hard to find a vacuum sensor for the arduino.

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. That makes the math in the arduino sketch so easy. With 0 kpa vacuum on th port the signal out to the arduino would be about 4 96 vdc.

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. 3 0 out of 5. 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. The vacuum gauge outputs 0 10vdc.

The oled screen. Link to my website for diagrams code and resources to recreate my experiments. At 50 kpa that signal is about 4 95 vdc so it would be 90 mv per kpa.
