AD8232 ECG Module Heart pulse monitoring sensor

Description

AD8232 ECG Module  is a Heart pulse monitoring sensor. It is integrated with AD8232 IC from Analog Devices. The chip extracts, amplifies, and filters biopotential signals for biopotential measurement applications (like ECG and others).

Additionally it has pins like the right arm (RA), left arm (LA) & right leg (RL) pins to connect custom sensors. Also has an LED indicator used to indicate the heartbeat rhythm of humans. Moreover, it comprises a function like quick restore used to decrease the length of long resolving tails of the HPFs.

Features of the AD8232 ECG Module 

• Has a Fully integrated single-lead ECG front end
• It has a Common mode rejection ratio of  80 dB (dc to 60 Hz)
• Has Two or three electrode configurations
• Additionally, its Qualified for automotive application
• Also has a Single supply operation of 2.0 V to 3.5
• Last but not least, it has a fast restore feature that improves filter settling

Applications of Heart pulse monitoring sensor

• It is used for Fitness and activity heart rate monitors
• Also used as a Remote health monitor
• In addition it is used as Game equipment
• Lastly as a Bio electricity signal collection

• Pin Description of the Module

  Pin Name	Description
  GND	Power Supply Ground
  3.3v	Power Supply 3.3v
  Output (ADC)	Operational Amplifier Output. The fully conditioned heart rate signal is present at this output. OUT can be connected to the input of an ADC.
  LO-	Leads Off Comparator Output. In dc leads off detection mode, LO− is high when the electrode to −IN is disconnected, and it is low when connected
  LO+	Leads Off Comparator Output. In dc leads off detection mode, LOD+ is high when the +IN electrode is disconnected, and it is low when connected
  	Shutdown Control Input. Drive SDN low to enter the low power shutdown mode.
  RA (Right Arm)	RED Biomedical electrode pad RA(input). Instrumentation Amplifier Negative Input. −IN is typically connected to the right arm (RA) electrode
  LA (Left Arm)	YELLOW Biomedical electrode pad LA(input). Instrumentation Amplifier Positive Input. +IN is typically connected to the left arm (LA) electrode
  RL(Right Leg)	GREEN Biomedical electrode pad RL(input). Right Leg Drive Output. Connect the driven electrode (typically, right leg) to the RLD pin.
  3.5mm ECG Biomedical Electrode Connector Jack	Combine Biomedical Electrode pad Connector of RA, LA, RL
