Note: The sensor must first calibrate the resistance of the thermistor NTC; The sensor test is affected by factors such as black body temperature, distance, and environment. The V-T table is for reference only. The V-T meter needs to be calibrated before use. The output voltage of the sensor is easily affected by the NTC resistance value. It is necessary to increase the thermal resistance and heat capacity to increase the temperature stability. Generally, metal (copper, aluminum) kits are used; In order to reduce the thermal interference between the sensor pins, the sensor pins should be thermally isolated when making a PCB. Frequent, excessive vibration, strong impact or collision will cause resonance inside the sensor to break.
