AD8232 sensor module

Single Lead Heart Rate Monitoring Front

The AD8232 is an integrated front-end for the signaling of cardiac bioelectric signals for heart rate monitoring.

The AD8232 is an integrated front-end for the signaling of cardiac bioelectric signals for heart rate monitoring.

Integrated signal module for ECG and other bioelectric measurement applications. The device is designed to amplify and filter weak bioelectric signals in the presence of noise generated by motion or remote electrode placement. The design allows the output signal to be easily captured by an ultra-low power analog digital (ADC) or embedded microcontroller.

The AD8232 uses a bipolar high-pass filter to eliminate motion artifacts and electrode half-cell potential. The filter is tightly coupled to the instrumentation amplifier structure, enabling single-stage high gain and high pass filtering, resulting in space and cost savings.

The AD8232 uses an unused limit amplifier to create a three-pole low-pass filter, eliminating additional noise. Users can select all filters cut off frequencies to meet the needs of different applications.

To improve the mode rejection performance of line-frequency systems and other unwanted interference, the AD8232 has a built-in amplifier for driven lead such as right-hand drive (RLD).

The AD8232 includes a fast recovery feature that reduces the otherwise long build-up of the long tail high-pass filter. If there is a sudden signal change in the amplifier rail voltage (eg lead disconnection situation), the AD8232 automatically tunes up the filter cut-off state. This function allows AD8232 to achieve fast recovery and therefore accurate measurement value as soon as possible after the lead is connected to the electrode of the measured object.

Guaranteed performance over the rated temperature of 0 °C to 70 °C and the operating temperature range of -40 °C to +85 °C.

The AD8232 single-lead heart rate monitor is effective for measuring the electrical activity of the heart.
Electrical activity can be plotted as an ECG or electrocardiogram. and analog output reading.
3. The ECG is very noisy. The AD8232 single-lead heart rate monitor acts as an amplifier and is able to receive clear signals with PR and QT intervals. 4. The AD8232
is an integrated signal module for ECG and other biopotential measurement applications.
It is designed to, amplify and filter small biopotential signals in the presence of noise conditions. 6.
The AD8232 Heart Rate Monitor disconnects nine connections from the IC, and can solder pins, wires or other connectors to it.
7. Use Arduino or other boards, SDN, LO+, LO- output 3.3V, GND provide necessary pins for running this monitor.
The RA (right arm), LA (left arm) and RL (right) pins are available on this board to connect and use your own sensors.
There is also an LED indicator which can beat the rhythm of the heartbeat.
10. The use of the heart monitor requires a biomedical sensor pad and sensor cable, you can find the product introduction below.
