Arduino Vacuum Gauge Sensor

Arduino vacuum gauge sensor. That makes the math in the arduino sketch so easy. Initial build used a 10k pot in place of a vacuum gauge to make it simpler. Link to my website for diagrams code and resources to recreate my experiments. 3 0 out of 5.
Ignore the humidity sensor that was for something else. Thakur definition pressure is defined as force per unit area that a fluid exerts on its surroundings. 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. 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. Sensore pressione md ps002 vacuum sensor absolute pressure senso for arduino. The oled screen. With 0 kpa vacuum on th port the signal out to the arduino would be about 4 96 vdc.
Also the vacuum version of the sensor is mpxv5050vc6t1 and is made by nxp usa for about 10 each. It has a measuring range of 2 9 psi to 36 3 psi absolute. It outputs a temperature compensated analog voltage that is proportional to an absolute pressure. I can control the vacuum pumps easily enough but it is hard to find a vacuum sensor for the arduino.
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 pressure sensor for arduino. The vacuum gauge outputs 0 10vdc.
