In order to make your life easier, a 8-SMD Module package includes this transducer. If you want reliable results, you should set the transducers' temperature to -40°C~125°C. 8 pins must be connected in order for the transducer to work properly. In the case of nominal supply current 1.5mA, the transducers can operate normally. In the case of transducers, a maximum voltage of 5.5V can be applied without causing damage. The current of the transducers should not exceed 1.5mA, otherwise it will be dangerous.
