Digitise an older engine - ESP32

[Techstyle]

Great to see more people doing this, so here is mine:

My engine monitor consists of:

• Oil Pressure - requires a pressure sender and a port on the engine to connect to.
  
• RPM - requires a pulse from the spinning engine, this is usually the 'W' terminal or Tachometer Signal wire.  This could also be done using a flywheel sensor or something similar
  
• Fuel Burn Rate - this will be calculated from the RPM
  
• Temperature Sensors - I am using 1-Wire sensors for the following:
  

1. Oil Temperature
   
2. Aft Cabin Temperature
   
3. Exhaust Elbow Temperature
   
4. Exhaust Barrel Temperature
   
5. Alternator Temperature
   

• Environmental Sensor - this device will report Temperature, Relative Humidity and Air Pressure in the engine bay
  

Here is the Schematic
   
Here is a pic of the box
   
Here is a KIP window with the gauges

There will be a video coming out on the 25th January about it
