ALLNET 4duino EKG-sarja (ALL-4duino-EKG) - AD8232 EKG-anturimoduuli Arduinolle

The ALLNET 4duino EKG Kit (ALL-4duino-EKG) is a complete single-lead electrocardiogram (ECG/EKG) sensor kit designed for Arduino-compatible platforms, including the 4duino. Based on the Analog Devices AD8232 integrated instrumentation amplifier, this kit provides high-quality bio-potential measurement for heart rate monitoring and educational projects. The kit includes the AD8232 module, electrode cable, and disposable snap-on electrodes, making it easy to get started with ECG signal acquisition.

Advantages

This kit offers a low-noise, high-common-mode rejection ratio (CMRR) solution for capturing clear ECG signals. The built-in high-pass and low-pass filters reduce noise and artifacts, while the Right Leg Drive (RLD) circuit further minimizes interference. The heart rate synchronization LED provides visual feedback, and the analog output allows direct connection to microcontroller analog pins. Operating at 3.3V to 5V DC, it is compatible with most Arduino boards.
