6-12V Piezo Buzzer (Big) Use this economical piezo-electric buzzer in experiments that require a doorbell or buzzer. This electric buzzer works off 6-12V volts. We recommend our 6-volt or 9-volt battery. A Piezo buzzer is an electronic device commonly used to produce sound. Lightweight, simple construction and low price make it usable in various applications like car/truck reversing indicators, computers, call bells, etc. It is the phenomenon of generating electricity when mechanical pressure is applied to certain materials and vice versa is also true. Such materials are called piezoelectric materials. Piezoelectric materials are either naturally available or manmade. Piezoceramic is a class of manmade material, which poses a piezoelectric effect and is widely used to make a disc, the heart of a piezo buzzer. When subjected to an alternating electric field they stretch or compress, in accordance with the frequency of the signal thereby producing sound. The piezo buzzer produces sound based on the reverse of the piezoelectric effect. The generation of pressure variation or strain by the application of an electric potential across a piezoelectric material is the underlying principle. These buzzers can be used to alert a user of an event corresponding to a switching action, counter signal, or sensor input. They are also used in alarm circuits. check out : TREASURE HUNT USING ESP32 (BLE SCANNER) Features: Wired Plastic Shell Active Piezo Electronic Alarm Buzzer Operates in a wide range of voltage (9V to 24V) Long life and stable performance Lightweight with a simple construction Piezoceramic material used for the disc, providing piezoelectric effect Produces sound based on the reverse of the piezoelectric effect Applications: Alerting or alarming circuits DIY projects requiring an audible alert IoT (Internet of Things) applications Security systems for audible warnings Use in conjunction with switches or sensors for immediate attention
