Grove Chest Strap Heart Rate Sensor
Last updated
Last updated
This heart rate chest strap kit contains a chest belt and a 5.3 KHz AM receiver module. The heart rate measurement kit can be used to monitor the heart rate of patients and athletes, meanwhile the result can be displayed on a screen via serial port and saved for analysis. The entire system has lots of advantages, e.g. high sensitivity, low power consumption and portability. Because the modules communicate with each other via AM, it is very convenient to let you move (notice that the effective distance is 30cm).

Heart rate monitor.
Caution
The chest belt is powered by a CR2032 coin battery. Open the back cover with a coin to replace it.If not used for a long time please remove the battery.
The following sketch demonstrates a simple application of using the Chest Strap Heart Rate Sensor to measure heart rate.
Connect this module to the digital port D2 on your base shield. And connect Grove-LED to Digital port 4.
Plug the Base Shield into Arduino/Seeeduino.
Copy and paste code below to a new Arduino sketch.
Upload the code.
This is the signal when we are measuring the heart rate:
In the first of the figures which is a waveform diagram of the detected heartbeat, a high pulse comes when beating.
Notes
1) The chest belt's wings must have contact with your skin to get a high accuracy.
2) The maximal distance between chest belt and receive module must be less than 30cm.
