How to wiring NTC temperature probe.Human Body Motion Sensor

　　Under normal circumstances, to connect the wire of the NTC temperature probe, a thermistor is needed to welded between the controller's simulation pin and the ground wire, and a fixed value resistance value is used between the pin and 5V. The best value of the fixed resistance value depends on the temperature range you want to measure.

　　Reference of fixed value:

　　1. If you use at room temperature, use 0 ~ 50K resistance (47K).

　　2. If you want to measure the water temperature (0 ~ 85C) in the car, you can use ~ 5k6 (see the data table).

　　3. Since you are still at a lower water temperature, you can use 10K resistance to coordinate.

　　4. Because most thermistor code is assumed that the fixed resistance value of 10K is assumed (can be changed in the code).
