Perisaltic pump
Perisaltic pump -
This is the first of two perisaltic pumps I want to disable the "drip-sensing" feature of its circuit. The pump is manufactured by Novartis Nutrition. It is a "COMPAT feeding pump", model number 199235. Where it is marked with the number 1, is the location of the drip sensor.
After the sensor is removed, I found it to be comprised of two parts, labeled A and B. I'm guessing the parts do the actual "drip-sensing" are photo diodes. They look identical and each one has one long and one short leg (maybe they're cathode and anode similar to LEDs).
Two shots of the circuit board and the motor.
Two pictures of the firmware chip.
