INGHAI GU14A03L01-A26 40kHz Plugin Ultrasonic Receiver & Transmitter

The transducer has a voltage rating of 140V. This refers to the maximum voltage the piezoelectric element can handle, not a recommended operating voltage. In practice, you will need an external driver circuit (often using a transformer or high-voltage driver IC) to generate the high-voltage, short-duration pulses required to excite the transmitter. The receiver side typically interfaces with lower-voltage amplifier and comparator circuits.

Yes, but not directly. This is a raw transducer pair requiring external electronics. You will need to design or use a dedicated driver circuit to generate the 40kHz, high-voltage pulses for the transmitter. For the receiver, a signal conditioning circuit with amplification and filtering is necessary to process the weak echo signal before feeding it into a microcontroller's input pin for time-of-flight measurement.

The sensing range is not specified by the transducer alone; it depends entirely on your system design. Key factors include the transmitter drive power (voltage and current), the receiver circuit sensitivity and noise filtering, the acoustic environment, and the target's size and material. With proper driver and receiver circuits, ranges from a few centimeters to several meters are possible for 40kHz systems.

"Plugin" indicates the transducer is designed with pins for direct soldering or insertion into a printed circuit board (PCB). This provides a secure mechanical and electrical connection, making it suitable for embedded systems and permanent installations, as opposed to sensors with wire leads or specific connectors.
