Hi!
I have recently bought a Heart Pulse Sensor. Then, to check whether the sensor is working correctly or not, I uploaded this below code:
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A0);
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}
I know, that this code doesn't calculate the actual BPM. It sends 380-400 sensor value through
the Serial monitor, while the sensor is not being pressed by my finger. But when I press it with
my finger, the sensor value doesn't even come out of the range 380-400. But the sensor value was supposed to jump over 500 when a beat happened.
I think, that probably means my sensor is unable to detect beats. And now, my question is, why
my sensor is unable to detect beats?
After looking at some forums, I learned that this sensor can be a clone. After looking at my sensor
carefully, I found some little differences in my sensor than the sensors other people used in their
tutorials. And, the most spottable differences were:
*the colors of my sensor's pre-soldered jumper wires were different than other sensors.
*"pulsesensor.com" was written in the other sensors, but it wasn't written on my sensor
There were also some other differences. I have attached three pictures(size less than 800kb)
of my pulse sensor in the attachments option below. And one picture I attached from the
pulsesensor.com website.
My final questions:-
- Why my pulse sensor is unable to detect beats?
- Is my pulse sensor a clone or not?
- If it is a clone, can it be fixed som how?
4? Do I need to buy another one?
That's all I know. Can anyone help me! Any help appreciated.
Thanks a lot!
