Heart Beat Sensor Module

The heartbeat sensor is based on the principle of photo phlethysmography. It measures the change in volume of blood through any organ of the body which causes a change in the light intensity through that organ (a vascular region). In case of applications where heart pulse rate is to be monitored, the timing of the pulses is more important. The flow of blood volume is decided by the rate of heart pulses and since light is absorbed by blood, the signal pulses are equivalent to the heart beat pulses.

আমি এটা নিয়েছি, কিন্তু sensor এর উপর আঙ্গুল রেখে নাড়াচাড়া না করলে সিগন্যাল আসেনা। আর BPM ভিন্ন ভিন্ন value দেখায়। code এখানে যেটা দেয়া আছে সেটাই ব্যাবহার করেছি,

সেন্সর এর উপর হাতের আঙ্গুলটি আলতো ভাবে (soft-touch) রাখুন । প্রয়োজনে আঙ্গুলটিকে capacitor পর্যন্ত এগিয়ে দিন । আঙ্গুলটি সঠিকভাবে স্থাপিত হলে সবুজ LED টি blink করতে শুরু করবে ।

does it detect light intensity in blood?
