I just started my journey here and I wanna know if its possible for me to make a calorie and heart rate monitor using piezoelectric sensor with lcd i2c display :DD wishing someone to respond, it will be a big help for my project.... thank you ---

A heart rate monitor might be possible not sure. There exist good sensors for heart rate A calorie monitor, I have no idea ---

> [@ramenlord69](#): > > I wanna know if its possible for me to make a calorie and heart rate monitor using piezoelectric sensor with lcd i2c display : Since calorie is a unit of heat. Relating that to a human actually uses kilo-calories. You can compute the kilo-calories by knowing the body mass (weight) and the temperature rise during exercise. My treadmill asks for my weight and then computes kilo-calories while I walk. Must have some formulae that I don't know about. You can likely come up with a formula for what ever you are wanting to know about calories. ---

Hi @ramenlord69 , there are several heart beat sensors available for Arduino use, e.g. [https://sensorkit.joy-it.net/en/sensors/ky-039](https://sensorkit.joy-it.net/en/sensors/ky-039) based on optical detection. There is also a project named "calorie meter" that uses an accelerometer to measure movements and calculate calorie consumption...

good day kind sir, in my case my professor only instructed me to mainly use piezoelectric sensors for detecting heart rate and reading burned calories. In this case, is there a possible formula for this? ---

You can use a piezoelectric sensor to measure heart rate by programming it in a way to detect the pulse rates in any of the superficial arteries of our body. You can connect it to an arduino and display data on an lcd or oled or you can transmit data wirelessly using an esp. For Calorie measurement it isnt directly possible but as mentioned in post #3 you can use a person weight and measure it. You can probably attach the piezoelectric sensor in a shoe and measure the pressure applied while running ---

I have read somewhere in the Medical Hacks section of "Hackaday Blog" and thought to give it a try. Also I've added a Processing sketch that...
