Description

technical field

[0001] The invention relates to the field of sensors, in particular to a thermal sensor. Background technique

[0002] Thermal sensors are conversion devices that convert temperature into electrical signals, and can be divided into two categories: active and passive. The working principle of the former is pyroelectric effect, thermoelectric effect, semiconductor junction effect. The latter works on the thermal sensitive properties of resistors, accounting for about 55% of thermal sensors.

[0003] When the existing thermal sensor is in use, the signal line is generally made of soft material. When the position is adjusted in the measured environment with more impurities or hard flocs, it takes a long time to adjust to the designated position. , thereby increasing the difficulty for users to use. Therefore, it is necessary to provide a new thermal sensor to solve the above technical problems. Contents of the invention
