Tri-Tone Buzzer
₹180.00
In StockA Tri-Tone Buzzer is an audio signaling device that produces three distinct tones in a sequence or pattern. It’s commonly used in alarms, emergency systems, and attention-grabbing devices to indicate different conditions or alert levels.
Description
Unlike a standard buzzer that emits a single tone or continuous beep, a Tri-Tone Buzzer creates a sequence of three different audio frequencies, often in a repeating pattern. This makes it more noticeable and suitable for environments where different sound cues are required.
The tri-tone sound can be generated using:
- Oscillator circuits (with 555 timers)
- Microcontrollers (like Arduino or PIC)
- Audio ICs (like UM3561, HT2811)
Each tone is generated at a different frequency, typically around 500 Hz, 1 kHz, and 2 kHz, with brief delays or switches in between to make the pattern recognizable and rhythmic.
Applications:
1.Emergency Alarms
1.Used in fire alarms, hospital alerts, and evacuation systems.
2.Security Systems
1.Alerts with distinct tones for intrusion, power failure, or tampering.
3.Vehicle Warning Systems
1.Multi-tone indicators for seatbelts, doors, or engine alerts.
4.Industrial Equipment
1.Warns workers of malfunction or operational hazards.
5.Door Bells & Attention Systems
1.More noticeable than single-tone buzzers.

- A rain alert system with an LCD display and buzzer, controlled by an 8051 microcontroller, is designed to detect rainfall and provide real-time notifications. The system uses a rain sensor to detect moisture or rainfall, and the microcontroller processes the sensor data. When rain is detected, the 8051 triggers a buzzer to alert the user audibly and displays the rain status on an LCD screen.

To measure distance using an ultrasonic sensor and display the result on an LCD with an 8051 microcontroller, you’ll need to interface several components: an ultrasonic sensor (e.g., HC-SR04), an LCD (e.g., 16×2), and the 8051 microcontroller.

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.

A Light Activated Motor Controller using IC 555 is a simple electronic circuit that turns a motor ON or OFF based on the presence or absence of light. It uses a LDR (Light Dependent Resistor) as a light sensor and the 555 timer IC in a comparator mode, along with an LED to indicate the motor’s status.

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.
