1. Based on what I understand, I think their outputs are both voltage readings; however, I can't find any voltage-temperature conversion table on their datasheets. How to convert their output to the temperature reading? If the outputs are not voltage readings, what their outputs are and how to get the temperature readings eventually?
2. For these two sensors, do I need to code both of them if I want to use them to take measurements?
3. For ZTP-135SR, I know that I need to build a circuit for it. However, what connections are required for operation. In other words, how to connect the circuit with the sensor and how to connect the entire circuit with the Arduino board?
4. What is the distance range to operate the sensors successfully? In other words, if I want to use them to measure the temperature, how far I can place the IR sensors to the battery which is going to be measured.
