Ultrasonic mist maker circuit Transducer driver circuit. Below is the circuit diagram of the final part of the project — the transducer driver. As shown in the circuit diagram, it’s a tricky ...

The simplest piezo drive circuit consists of a transducer and a switching transistor (Figure 1). The voltage across the transducer cannot be greater than the supply voltage, which places an upper ...

Aside from the price, these kits have the added advantage of including waterproof ultrasonic transducers, perfect for an outdoor weather station, and all the required circuitry to drive them. Some ...
