Working Principle • Microcontroller is used as the controlling unit. • The developed flow sensor is attached to the neck of the blood bottle. • The output signal from the flow sensor is amplified and then feed to microcontroller’s interrupt pin to calculate drop interval. • A high precision blood flow controller is attached with blood delivery pipe. • If any mismatch detected, the microcontroller sends control signal to blood flow controller in order to correct.
