This a neat little sensor that uses an LED and light sensor to detect minute changes in light absorption as your blood pulses through your finger. I was able to hook it up to a small OLED display and get a nice graph of my pulse. I don't believe that this is a medical quality sensor. I had to fiddle to get my finger in just the right spot to get a good reading, but it was still pretty cool to play with. The signal generated from the device is an analog signal that needs to be connected to one of the ADC pins of your MCU. The device does not come up with the pins pre-soldered, but wasn't a big deal to solder them myself. The cable was also different than pictured. I received a female-female jumper cable rather than the female-male cable pictured. Which one you actually need depends on what you intend to plug it into. The male jumper end is useful when going into a breadboard but the female works great when you are connecting directly to a pin on the MCU.

I purchased these units because my soldering equipment is in storage and I didn't want to have to deal with digging it out. Every image shows the sensor with the pins soldered on and the description does not state that any soldering is required. If I thought I would have to solder these sensors, I would have purchased a different brand...that is probably what the seller was hoping for. I will NEVER order from this seller again. Leaving out information is as dishonest as fraudulent information.

Connector not soldered to PC board. Cabling shown in ad is male-female but delivered with female-female. Sure hope this works because everything else is wrong!!
