In this video I will show you how a commercial smartwatch measures and monitors your heart rate and afterwards I will show you how to create a DIY circuit that can basically do the same with the addition that it can also store the heart rate data on a micro SD card. At the end I will then compare both heart rate monitors in order to find out whether my smartwatch still works fine. Let's get started!

We live in the age of Arduino, where every sensor gets one microcontroller... Couldn't that STM32 handle an OLED display and logging? And why use an SD card? The atmega328p has 1k EEPROM, and even some STM32 have it in similar size. I know this is just a prototype and for testing, but I really, really despite the wastefulness of the „Arduino age” in general. (Here I have to mention that I don't hate anyone for doing this, I hate the trend that is going on.) And it's especially sad, because this trend reduces the need for clever design choices, something I really enjoy to see.
@nout4269 4 роки тому
Absolutely agree, and the same trend is happenning in computer programming. When cheap components and large amounts of computing power are available at little cost, people stop caring about efficiency and performance, and just start piling levels of abstraction to fix their problems. Although to be fair, Scott probably doesn't have the time to develop a custom PCB and µC specific program that goes with it for each project.

i kept thinking the same. there you got that cpu that's probably 10 times more powerful than your arduino, in a nice case that looks like it has some space left over for display,battery and card slot if you play a bit of tetris and desolder that connector, and instead let's just add another cpu, custom case, and loads of hotglue? :P

Hi, I though the same, the STM32 can handle a lot with 72mhz ,128kb and 48 pins. I guess they used with sensor because it have ADC and cost £4.
@resneptacle 4 роки тому
How do you plan on easily getting the data off? Through the serial port with custom written software on both ends thst has to be updated for new systems and be somehow cross-platform compatible for a "proper" setup... It's easier to just use a small SD Card that really doesn't cost much nowadays

The heart rate sticking to ~161 will be the sensor detecting your running cadence. It's a common issue with wrist based heart rate measurements. I opt for a chest mounted HRM for more accurate data. Would be great to see a video making your own chest HRM as they measure differently.

I really like the little video segments you do before the project, I think I speak for a lot of people when I say please keep doing them!
@kwakeham 4 роки тому
Having worked on optical heart rate technology I can tell you a few things. For sports where movement happens the signal is not close to stable, but you first need to start with an optimized mechanical package with optimized brightness and spacing and a large photosite. Most of these early and cheap "all in one" led / sensor / AFE can't work on wrists or arms well due to the lower signal and are now relegated to the "finger HRM sensor" pile, and low end cheap "smart" watches where you can fight a little to get them to work while not moving. The movement generally means the signal gets lost, completely -- that's what you're seeing. The better ones use algorithms that take your history and accel vibration to estimate your HRM. They've gotten really good at guessing what your HRM is..... not directly measuring. While still filtered a HRM chest strap only uses algorithims to clean up noise and variation -- that's closer to a real reference, not another guestimator.

Great video. It demonstrates that it is possible to build your do it yourself heart rate watch. Unfortunately, only one heart rate sensor is very inaccurate. There are now very accurate heart rate watches available like the Apple watch or the Huawei watch 3 GT pro. Unfortunately, they do not allow easy acess to sensor data. A do it yourself watch with more sensors would be highly desirable. We did search a multi sensor heart rate board, but we could not find one. Could you find somewhere a multi sensor heart rate board, to obtain a more accurate heart rate watch?

If you wouldn't live in the age of arduino, you could have used the pure sensor, display and a uC on a custom pcb to make the project way cheaper, smaller and provide a way higher value gain, writing your own code. All these modules may be fine for a first test, but a finished project schould be more polished.

So far from what i understand,firm contact,Multi emitters of Green Led and Photo diodes (3 heart rate data across 3 different points) and instead of calculating in real time,use the error correction algorithm efficiently. Use of Historical sample data for future predictions along with help from accelerometer to subtract noise due running. There are many more. You have to invest quite a lot into this to effectively make this sensor into what we call "Medical Grade Monitor"

Hey Scott...I've had an idea for some time now: Making a watch that zaps you with electricity at a set time. I've always had trouble waking up in the morning, and I think this could really be the solution. My plan is to take one of those zapping/pranking pens (high voltage, low amp charge) and connecting it to a simple wrist watch capable of alarm. Problem is I'm just a beginner with electrical projects and don't know where to start. I hope you consider this as one of your next video. There is one such commercial product called Pavlov aimed not only at waking up, but to all sorts of activities someone would want to stop doing. But it's incredibly expensive and has useless features (bluetooth connection and smartphone operation) I don't need.

Great video Scott, I got a doubt: How do some manufacturers manage to calculate (because as far as I know, they don't sense) blood pressure? Thanks a lot buddy, regards from México!
@OddJobEntertainment 2 роки тому
I'm a medical assistant and measuring blood pressure is my bread and butter. The short answer is they don't do a good job. But to explain that further, let me explain how it is done manually, which is still the most accurate. The cuff is inflated to a number higher than your blood pressure and with the stethoscope we listen for a heart beat. Once it drops to the right pressure, we can hear your heart beat in your arm. We record that number as the systolic pressure (top number). As the pressure continues to drop we eventually stop hearing your heartbeat. Once we no longer hear it, we record that pressure as the diastolic pressure (bottom number). Automated cuffs try to do the same task of 'listening' with pressure sensors and airflow sensors. They do a reasonably good job but it is still not as trustworthy as a manual reading. Watches try to do it by using the same LEDs we saw in this video to estimate the pressure based on pulse transit time. It's a secondary observation at best where it tries to correlate the time it takes for a pressure wave to travel through your wrist with you blood pressure. It needs quite a bit of work still.
