Engine Monitor
Overview
The [Avionics Anonymous Engine Monitor] interfaces with common engine sensors. It provides 4x 0-5V analog inputs, 4x thermocouple inputs, and an RPM input. Connects to Pixhawk and other similar autopilots via UAVCAN. Comes fully assembled, ready to use!
Note: This device currently requires custom development to integrate with most autopilot software. Please contact us if you need assistance.
What makes it special?
4x 0-5V analog inputs (with under- and over-voltage protection)
4x thermocouple inputs (K-type by default)
1x RPM input for connection to hall-effect sensors or output from electronic ignition systems
Customized software configuration for your application
Robust UAVCAN interface is compatible with most Pixhawks and similar autopilots

Wiring
The Engine Monitor is connected to your autopilot via CAN bus. The wiring is per the pinout below, or the necessary cables can be purchased to connect to your system right out of the box:
CAN Harness - connects between the autopilot and a CAN node and between each CAN node on the bus
CAN Terminator - connects to the last device on the CAN bus
Analog inputs are connected to each of 4x Molex SL 2-pin locking headers. Polarity is marked on the board.
Thermocouples are connected to each of 4x screw-terminal blocks. Polarity is marked on the board.
The RPM signal is connected to a Molex SL 2-pin locking header. Polarity is marked on the board.

Configuration
Autopilot Configuration
Currently, this device is not natively supported by common autopilots, and the firmware of this device itself is customized to your needs. We can set it up to publish CircuitStatus, FuelStatus, Temperature, RPM, or any other default UAVCAN messages, or define your own DSDL and we'll integrate it. Add your own support for processing these UAVCAN messages in your autopilot, or get in touch with us to ask about developing this support for you.
Node Configuration
The Engine Monitor node has a number of parameters accessible via the UAVCAN interface. These may be set following the steps outlined here
