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.

An AC Current Detector is a device or circuit that senses the flow of alternating current (AC) through a wire or appliance. It typically uses components like a current transformer (CT) or hall effect sensor to detect AC current and activate an indicator such as an LED or buzzer.

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 Digital Lock System is an electronic security project designed to control access using a password entered via a keypad. It utilizes an Arduino, keypad, LCD, servo motor, and buzzer to provide a safe, automated locking mechanism. When the correct password is entered, the lock opens; if the wrong password is entered, an alert is triggered. This project is widely used in home security, lockers, safes, and access-controlled systems.

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.

An Electronic Dice is a digital version of a traditional dice, which generates a random number (1 to 6) and displays it using LEDs or a 7-segment display. It uses components like a 555 timer, counter IC (like CD4017), or microcontrollers such as Arduino to simulate dice rolls electronically.

A Flip-Flop LED Flasher is a simple electronic circuit that alternately turns two LEDs on and off in a continuous loop, creating a blinking or “flashing” effect. It’s commonly built using transistors, resistors, capacitors, and LEDs, forming an astable multivibrator — a basic circuit that oscillates between two states without any external triggering.
It’s often used for decoration, indicators, or learning basic electronics.

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.

An Electronic Coin Toss circuit is an electronic version of the classic coin flip — often used to make quick decisions, settle disputes, or play games. It mimics the randomness of a real coin toss using digital logic or a microcontroller to generate a pseudo-random result and display it using LEDs or a text display (e.g., “Heads” or “Tails”).
