Description

technical field

[0001] The invention relates to a temperature measurement system, in particular to a community environment temperature measurement system based on a voltage stabilizing circuit node power supply, which belongs to the field of environmental monitoring. Background technique

[0002] Temperature is a very important environmental parameter. People's lives are closely related to the ambient temperature. In the process of industrial production, it is necessary to measure the ambient temperature in real time. In agricultural production, temperature measurement is also inseparable. At present, in meteorological stations and radiosondes, etc. In the field of environmental detection, traditional temperature sensors mostly use platinum resistance or thermistors for temperature measurement. Because ice, snow, raindrops, cloud droplets, dew and other liquid or solid water may be adhering to the surface of the sensor, the evaporation and heat absorption of cloud droplets, ...
