As a convenience, the transducer is included in package 4-SIP Module. Reliable performance is ensured by setting the transducer temperature to -40°C~85°C. With a voltage supply of 2.5V~16V, the transducers can function properly. There is a requirement for connecting the 4 pins to make the transducer work properly. In order for it to work, the voltage released by the transducers must be 100mV. For the transducers to continuously work at the rated ambient temperature, DC voltage should be 10V.
