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.

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.
