- 1 X 15k resistor
- The resistors are used for a voltage divider as the sensor outputs 5V and the ESP-8266 is 3.3V I should have used a 10K and 20K however did not haveone on hand.
- The sensor and Voltage divider is connected to A0
- The SSR is connected to D5
- You may need to alter the settings for the wifi side as well as adjust the calibration list for the pressure settings dependent on the PSU you have selected
- CONTROLL
- Its prety simple, Set your base levels in the code. these are
- float SetPressure = 40.0;
- float pressureWindow = 5.0;
- Then log in to the web interface and you can adjust the sliders to change your SetPressure and pressureWindow.
- SetPressure is the minimum pressure you want
- pressureWindow is the amount of pressure above your set pressure the pump will pump up to before cutting off.
