Description

The Pulse Sensor Module utilizes a green LED and a photodetector to perform photoplethysmography (PPG), detecting blood volume changes in capillary tissue. The onboard circuitry amplifies the small analog signal and filters ambient light noise, outputting a clean, readable pulse waveform. This digital signal can be directly sampled by a microcontroller’s analog or digital input pin.

Designed for ease of use, the module operates from a 3V to 5V DC supply, making it compatible with a wide range of development boards without requiring level shifters. Its low-current design ensures suitability for battery-powered applications, from fitness trackers to interactive art installations.

Frequently Asked Questions

What is the operating voltage range for this Pulse Sensor?

The Pulse Sensor Module operates from 3V to 5V DC. It can be powered directly from the 5V or 3.3V pins of most Arduino boards, ESP32, or Raspberry Pi Pico without requiring a voltage regulator.

How do I connect and read data from this sensor with an Arduino?

Connect the module's VCC to 5V, GND to GND, and the Signal pin to an analog input pin (e.g., A0) on your Arduino. Use the provided PulseSensor Playground library to read the analog waveform and calculate beats per minute (BPM). Example code is included for immediate use.

Can this sensor be used for continuous, long-term monitoring?

Yes, its low 4mA power consumption makes it suitable for battery-powered, long-term monitoring in wearable devices. For optimal signal quality in continuous use, ensure the sensor is firmly and consistently positioned, typically using a clip on a fingertip or earlobe.

What kind of output signal does this module provide?

The module outputs an analog voltage waveform that corresponds to the blood pulse. This signal has been amplified and filtered onboard. You read this analog value with a microcontroller's ADC to detect peaks and calculate heart rate. The signal pin can also be configured for a threshold-based digital pulse.
