One of the important factor in drug stuffs to a patient is to inject exact amount with stable flow rates. Since improper injection amount and flow rates would cause bad effect to recovery of a patient, the detecting sensors with high sensitivity is required for an injection pump systems performance improvement. In this study, the three sensors, piezo film sensor, photo transistor and photo array. were compared to find best one for an injection pump monitoring system. Using suggested data processing technique and photo array sensors, we could minimize the effect of interference, disturbance, illumination, and sensitivity change caused by sensor`s position. According to the experiments, the photo array showed the higher reliance than any other the three types of sensors.
