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 Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.

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.
