In order to make your life easier, a 10-SMD Module package includes this transducer. If you want reliable results, you should set the transducers' temperature to -40°C~125°C. Supply voltages as low as 3V~12V work well with the transducers. Temperatures of 125°C are the maximum operating temperatures of the transducers. It is impossible to operate the transducers below -40°C. If it is to work, the transducers' voltage should be 60mV. For continuous operation of the transducers at ambient temperatures, DC voltage should be 3V.
