| Abstract | The shortage of medical devices in rural Thailand, because a budget to limit and constrain. Therefore, a development of low cost medical tools as one of the solution. This paper proposes an improvement of low cost heart rate device and application in the local medical in Nakhon Phanom province Thailand. The hardware circuit, using the circuit instrument amplifier, low pass filter, auto adjust zero and the microcontroller, real time acquisition of the parameter of heart rate, first step , detect the heart rate per pulse and count the pulses for one minute to get the beats per minute detection pulse via a finger and measure the intensity of light. The pulse signal will be amplified and modification of signal to the microcontroller inputs. The count value of pulses per minute and show heart rate in bpm. The results have been compared with the experimental and medical criterion, the average error results approximate 1.31%, it is confirmed that the low cost device could be used in the target areas. |
