A Piezo buzzer is made from two conductors that are separated by Piezo crystals. When a voltage is applied to these crystals, they push on one conductor and pull on the other. The result of this push and pull is a sound wave. These buzzers can ...

Water proof type ultrasonic sensors were widely used for parking sensors, proximity sensors and level sensors, etc. With perfect seal these sensors can be used in a relatively poor environment such as dust and humidity.

We Supply normal, waterproof and special piezoelectric ultrasonic sensors, These products are used in remote control systems, distance measurement systems, back collision-avoidance systems, burglar alarms etc.
