In this video, I discuss the circuits I've built to get the ESP to read RPM, engine temperature and exhaust temperature as well as some off the shelf devices which are just 'plug and play'.
The Volvo Penta MD2030 heat exchanger is M18x1.5 thread. I used a KUS temperature sensor from ASAP https://www.asap-supplies.com/products/kus-insulated-earth-water-temperature-sender-120c-eu-m18x1-5-ke00018
BME and 1Wire came from PiHut.
Components from eBay and RS.
