Hi, Can it be operated by a 8Mhz board?Thanks!

We recommend you with this sensor:

We also have an onboard MCU on the sensor to run the heart rate algorithm.

Sorry we only got the sensor that could measure heart rate and oxygen saturation.

Can I measure both Heart Rate and PPG from the wrist?

I can it use on arduino uno board. But it didn't work on arduino yun board,when I run the digital mode ,the serial monitor showed nothing.

Hello
I used the sensor and tried to combine it with a servo motor, the servo continued vibrating without any command as the heart rate sampled.
any suggestion what makes the servo work and how can I fix it?
Thank you!

If the Heart rate Sensor can be driven by 3V3 then it would be no problem for a Raspberry Pi connection?

Hi! Would I be able to trim off the holes for the belt to make the sensor rectangular or would that interferre with the PCB?

Como estas buenas tardes aun dispones del sensor y que nomas incluye el envio el sensor y la pinza?

Hi,
Can you use an Arduino UNO or MEGA and do you have a code/wiring for this project?

Yes, it is compatible.

Yes, we can send it to Argentina.
You can refer to the wiki about heart rate measurement.
