SH-ESP32 Engine Top Hat (Engine Hat) is an add-on board for the SH-ESP32 for reading marine engine sensor data into the boat's Signal K or NMEA 2000 network.
Features
The Engine Hat allows you to measure common engine outputs:
- Tachometer (RPM) senders, either using dedicated tach senders or alternator W terminals
- Digital inputs such as engine alarms
- Tank senders
- Other resistive senders such as oil pressure senders with a resistance range of 0-300 ohm
It includes the following inputs:
- Four analog input sensors, usable either as 0-29V voltage inputs, or as 0-300 ohm resistance sensor input.
- Four digital input sensors, usable as alarm inputs or as frequency counters, suitable for tachometer signal inputs or fuel flow sensors. The voltage range is -30-30V, with a threshold level at 1.65V.
