Products Description
The main functions and uses of sunshine duration radiation sensors include the following aspects:
●Measuring sunshine hours: The sunshine hours sensor is used to continuously measure sunshine hours. When the radiation voltage value irradiated on the instrument is greater than a preset threshold (such as 200mV), the time is accumulated and reset at zero o'clock every day. The data collector automatically records it as sunshine hours1.
●Applications in meteorology, agriculture, forestry, breeding, construction and other fields: Sunshine duration sensors are widely used in research in meteorology, agriculture, forestry, breeding, construction and other fields. They can also be used in laboratories, urban lighting and other fields that need to monitor sunshine duration1.
●Application in the automotive field: In the automotive field, the sunlight sensor is also called the sunlight sensor. It is installed under the front windshield of the car. It uses a photodiode to detect the amount of sunlight entering the car and converts the sunlight into a current value and inputs it into the automatic air conditioning control unit, thereby adjusting the temperature and air volume in the car to ensure that the temperature in the car remains within the set comfortable range. In addition, the sunlight sensor is also used in the automatic headlight control system. By sensing the amount of sunlight, it provides an adjustment control signal for the automatic headlights2.
●Photovoltaic environment monitoring: Sunshine duration sensors are also important in photovoltaic environment monitoring. They are used to monitor the light conditions of photovoltaic systems and help optimize the operation and maintenance of photovoltaic systems.
