Measure Engine Temperatures with SH-ESP32
Table of Contents
Would you like to get better temperature monitoring for your boat engine? Are you worried about forgetting to open the water intake seacock? Is the coolant circulation working properly? We have prepared a tutorial that walks you through creating an inexpensive and easy to install but powerful temperature sensing device with the SH-ESP32 development board. The device measures the engine oil, coolant, and wet exhaust temperatures and transmits the data to your NMEA 2000 network or Signal K server.
