Heartbeat Detector
₹450.00
In StockA heartbeat detector is an essential device for monitoring heart health, providing real-time data about a person’s pulse rate. Whether in a hospital, gym, or a DIY electronics project, it demonstrates how biomedical signals can be measured and processed using sensors and electronics. It’s a valuable tool for both personal health awareness and professional medical diagnostics.
Description
A heartbeat detector is a biomedical instrument that plays a crucial role in health monitoring systems, used to measure a person’s pulse rate non-invasively. These devices are designed to detect the small physical or optical changes in the body caused by the rhythmic contraction and expansion of the heart.
The most common method uses a pulse sensor with a photoplethysmography (PPG) principle:
- An infrared (IR) LED shines light into the skin.
- A photodetector (photodiode or phototransistor) measures how much light is absorbed or reflected, which changes with blood volume.
- Each pulse causes a small fluctuation in the signal, which is processed using filters and amplifiers to detect heartbeats.
Other methods use piezo sensors that detect pressure changes in the arteries, or even ECG electrodes for higher accuracy.
Heartbeat detectors can be standalone devices or part of larger systems, such as fitness trackers, smartwatches, or patient monitoring systems.

This project involves controlling a DC motor’s direction using an 8051 microcontroller, with a buzzer and LED indicating the motor’s rotation state. When the DC motor rotates forward, the microcontroller keeps the buzzer and LED off. However, when the motor is rotated in reverse, the microcontroller triggers both the buzzer and LED to turn on as a visual and audible indication of the motor’s reverse rotation

A Touch ON/OFF Switch is an electronic circuit that allows a device to be turned on or off by simply touching a sensor pad or wire, instead of using a mechanical switch. It works by detecting a small electrical signal from the human body (capacitive or resistive touch) and using that to toggle the output state.
These switches are commonly used in modern electronics, home automation, and DIY projects due to their durability, aesthetic appeal, and user-friendly operation.

A solar-based LED system is a lighting setup that uses solar energy to power LED (Light Emitting Diode) lights. During the day, a solar panel captures sunlight and converts it into electrical energy, which is stored in a battery. At night or in low-light conditions, this stored energy powers the LED light.
These systems are eco-friendly, cost-effective, and ideal for off-grid or outdoor applications like street lighting, garden lights, and emergency lighting.

A Bird Bell is a device designed to either attract, entertain, or repel birds, depending on its purpose and context. Traditionally, it is a small bell-shaped object made of metal, ceramic, or wood, and is usually hung in gardens, balconies, farms, or near bird feeders. Its name comes from its interaction with birds — it may ring when birds land on it, brush past it, or when the wind causes it to move.

A traffic light control circuit using IC CD4017 is a simple digital electronics project that mimics the working of a real traffic light system. It uses the CD4017 decade counter IC along with a timer (usually 555 IC) to sequentially switch Red, Yellow, and Green LEDs, simulating the flow of traffic signals.

A Security Alarm Circuit using the LM358 IC is a simple yet effective system designed to trigger an alarm when unauthorized access or movement is detected. The LM358, a dual operational amplifier (Op-Amp), is used as a comparator to detect voltage changes from sensors like LDRs, IR sensors, or switches, and then activate a buzzer or relay.
