The ECG monitor sensor module is based on the AD8232 Analog Devices IC. This is an inexpensive ECG sensor used to measure the electrical activity of the heart. This electrical activity can be recorded as an ECG or ECG and output as an analog reading. The EKG can be very noisy and the AD8232 single channel heart rate monitor acts as an op amp to get a clear signal.
This sensor can be connected to Arduino / Raspberry Pi etc. Sample code is readily available on the internet. The
AD8232 is an integrated signal conditioning block for ECG and other biopotential sensing applications. It is designed to extract, amplify, and filter small biopotential signals in the presence of noisy conditions such as those produced by motion and the placement of remote electrodes.
The
AD8232 module disconnects nine connections from the IC where you can solder pins, wires, or other connectors. SDN, LO +, LO, OUTPUT, 3.3V, GND provide important pins for operating this monitor on Arduino or other development boards. This board has RA (right arm), LA (left arm), and RL (right leg) pins that can be used with your own custom sensors. In addition, there is an LED display that pulsates in time with the rhythm of the heartbeat.
