Types of temperature and humidity sensors
Digital temperature and humidity sensor: can convert temperature and humidity into electrical signals that are easy to measure and process, which is convenient for computers, Pl Cs, smart meters and other equipment to read directly.
Analog temperature and humidity sensor: transmits data through analog signals, suitable for traditional monitoring systems.

Basic concept of temperature and humidity sensor
Temperature and humidity sensor is a device used to measure ambient temperature and humidity, and is widely used in meteorology, agriculture, industry, warehousing and other fields. It can measure the temperature and humidity in the air through a certain detection device, and then convert it into electrical signals or other required forms of information output according to certain rules to meet user needs.

The role of water immersion sensors in intelligent transportation
A water immersion sensor is a device used to monitor whether there is a liquid leak in a specific area. Its working principle is usually based on the conductivity of the liquid. When the sensor comes into contact with moisture, a current loop is formed and an alarm signal is triggered. This sensor has applications in multiple industries, including data centers, communication rooms, power stations, warehouses, archives, etc.

Working Principle of Infrared Sensor
Basic Working Principle
Infrared sensors can sense heat and movement in the surrounding environment and are composed of an emitter and a detector. When working, the emitter emits infrared light, and the detector receives and produces output according to the changes in the received light. These sensors only measure infrared radiation, not emit, and are called passive infrared sensors.

Overview of Solar Radiation
Solar radiation refers to the energy transmitted by the sun in the form of electromagnetic waves, including electromagnetic waves and particle flows emitted by the sun into space. The energy transmitted by these radiations is called solar radiation energy. Although the solar radiation energy received by the earth accounts for only one billionth of the total radiation energy emitted by the sun into space, it is the main energy source for the movement of the earth's atmosphere and the main source of the earth's light and heat energy.
