Easy Pulse mikro – A mikroBus compatible pulse sensor

Easy Pulse mikro is a new addition to our Easy Pulse Sensor series. The word mikro signifies that it’s an add-on board in mikroBus form factor, which enables easy integration with mikroElektronika‘s numerous development boards. Similar to our original Easy Pulse V1.1 and Easy Pulse Plugin, it also operates on the principle of transmittance photoplethysmography applied to a fingertip using infrared sensors. Easy Pulse mikro provides all necessary instrumentation and amplification on board to detect the cardiovascular pulse signal from the fingertip. The output is a nice and clean analog PPG waveform that is routed to the AN pin of the mikroBus connector. Currently, you can buy this sensor from our Elecrow Store.

Easy Pulse mikro – A mikroBus compatible pulse sensor


  • Compatible with mikroBus socket.
  • Filtered and amplified analog PPG signal output (range: 0-3.3V).
  • On board potentiometer for adjusting amplifier gain, if needed (rotate clock-wise for increasing the gain).
  • On board LED for indicating the heart beat. It flashes synchronously with the heart beat on detecting the pulse from fingertip.

The following figure shows an actual PPG output waveform from Easy Pulse mikro. The pulse rate (or heart beat rate) can be computed from the time duration between any two peaks in the signal. This is described in more detail in a demo application provided later in this article.
