Mark W Kiehl was looking to build a project monitoring six thermocouples on an aircraft. The requirements:
- Read up to 6x K type thermocouples
- Display temperature readings and indicate visually if any are lower or higher than normal.
- Daylight readable display.
- 12 VDC power input
The circuit was designed using an Adafruit M0 Basic Feather along with:
As for the build:
The custom FeatherWing mounts to the 2.9″ Grayscale eInk / ePaper Display FeatherWing or the 2.9″ tri-color eInk display and accepts the mounting of up to 8x of the Adafruit Analog Output K-Type Thermocouple Amplifier – AD8495 Breakout.
Analog input connections A0 to A5 are routed to each of the thermocouple amplifiers, but each one has a pair of tabs with a thin trace that can be cut if the analog input assignments needs to be changed.
12 VDC input to the screw terminals provides 1A of 5V power to the Feather Vbus connection. The PCB overall dimensions are 80 x 65 mm. This PCB will mount directly behind the 2.9″ eInk display (centered), with the height of the PCB larger than the display in order to accommodate mounting of the thermocouple breakouts on the top and bottom.
