Heart Rate Sensor -

I bought a couple of Pulse Sensor modules for my new experiments from different online vendors, India and abroad. Sadly, the Pulse Sensors are awful. I had the worst time in my life trying to make them work. Multiple attempts after that, I finally got a sensible waveform in my Arduino Serial Plotter as shown next, but only one time. I know that the Pulse Sensor is not foolproof, and admittedly ...

MQ-7 Carbon Monoxide Sensor Circuit Built with an Arduino

The carbon monoxide sensor we will use is the MQ-7 sensor. This is a sensor that is sensitive to effects of CO. Carbon monoxide (CO) is a very dangerous gas which is odorless, colorless, and tasteless, so it cannot be smelt, seen, or tasted. A person really would have no idea that they are breathing in CO besides the fact that they would start ...
