Hi, I am very new to arduino, I am trying to follow this pulse sensor servo tutorial (link below): Pulse Sensor Servo Tutorial – World Famous Electronics llc.
But I don't have the pulse sensor that article suggested, instead I just bought MAX30102 heart beat sensor module from my local store, so I want to ask is it possible to use this module instead of that little pulse sensor?
Hi, welcome to this forum.
Can you tell which module you have ? Preferably with a link to where you bought it.
They are two different sensors. The PuseSensor has analog output and the MAX30102 uses a digital interface with the I2C bus.
Sparkfun sells the MAX30102 and has a library for it: https://www.sparkfun.com/products/15219.
This is the module i have :
https://www.jaycar.com.au/heartbeat-sensor-module-for-arduino/p/XC3740
That is a good module, it has a voltage regulator and I2C level shifters. It is compatible with 5V Arduino board and 3.3V Arduino boards.
Can you connect it to the Arduino and the I2C bus ? You need to connect 4 wires.
Then run a I2C Scanner sketch.
There is one in the menu of the Arduino IDE: File / Examples / Wire / i2c_scanner
Which board do you have ?
I am using arduino uno board.
I followed this guide:.
I saw a video they welding those 4 hole in that module, do I need to do that to be able to connect?
No, as long as the wires make good contact. You can press the module in a breadboard, or solder wires to it. If you use the pins, and they are not soldered yet, then you must solder them to the module.
Here is a tutorial that I found: https://diyodemag.com/education/what_the_tech_finger_pulse_heartbeat_sensor_module.
The picture is almost okay. It is powered with the 3.3V pin, but it will work better when powered (red wire) with the 5V pin.
Thanks for the reply, I am able to get it measure my heart rate now, but can this module replace that small pulse sensory and use it in this tutorial: Pulse Sensor Servo Tutorial – World Famous Electronics llc.
No, that is sadly not possible. The MAX30102 module is quite large indeed.
