Heart Rate Monitor Sensor Heart Rate Pulse Measurement Module Compatible with Arduino UNO R3 Board

Searching for an AD8232 ECG board will bring you to this device, but I believe this is just what it says, a pulse measurement module. When hooked up to an arduino, the 'pulse' output is high with a low pulse with each heartbeat. It's hard to find any documentation and none comes with device to use the apparent digital outputs. You'll have to do some simple coding to extract HR from the pulse intervals. The pads are reuseable(for a while at least). Cable is about 20" long. I didn't see the use case inititially, but if you hold the metal portion of the common and left snaps in one hand and the right snap connector in the other, the device can still extract your heartbeats. One could, say, put metallic pads on exercise bike handlebars and create a HR readout. I bought this by mistake, but I'm hanging on to it.
