What are the instruments that can measure the intensity of sunlight?

3415F Optical Quantum Tester, I am also considering whether to buy it now?

Solar lamps usually use a light-controlled sensing spine sail family to detect the ambient brightness to automatically turn on and off the light, ensuring that the solar lamp works in full sunlight and saves energy. Therefore, the instruments for detecting whether the solar lamp is normal mainly include the following:

Light Control Sensor Tester: It is used to test whether the light control sensor is working properly. The tester can simulate the environment with different light intensities, detect whether the light sensor can correctly identify the ambient brightness, and control the light switch.

Solar panel tester: It is used to test the output voltage, current, and power of solar panels. By testing the output capacity of the solar panel, you can judge whether the solar lamp can be charged normally.

Illuminance meter: used to measure the intensity of light and determine if the solar lamp is in full sunlight. If the value displayed by the illuminance meter is too low, it means that the solar lamp is not working properly.

Battery Tester: Used to test whether the battery of a solar light is working properly. By testing the voltage, current and other parameters of the battery, it can be determined whether the battery needs to be replaced or repaired.

Comprehensive tester: Some manufacturers provide comprehensive testers that can simultaneously test the working status of various components such as solar panels, light-controlled sensors, and batteries, and provide corresponding diagnosis and maintenance solutions.

The above are several common solar lamp testing instruments, which may vary from manufacturer to model. In practical application, the corresponding testing instrument is selected according to the specific situation of the solar lamp to ensure that the solar lamp can work normally.

Summary. Dear, hello, I am happy to answer for you, the measurement method of solar photometry, the determination of solar photometry needs to use two astronomical quantities, s represents the radiation energy received from the sun per unit time unit area in the universe space on the earth's position, and r, which represents the average distance between the sun and the earth. The common value of the constant is s=1366w m 2 and r=149618753000m.

Dear, hello, I am happy to answer for you, the measurement method of solar photometry, the determination of sunlight photometry needs to use two astronomical quantities, s represents the radiation of the sun per unit time and unit area in the universe at the position of the earth, and r, which represents the average excitation distance between the sun and the earth. The common value of the constant lead wheel is s=1366w m 2, r = 149618753000m.

Hello, dear, extended content: Light intensity can be measured directly with a RI beam intensity meter or a photoelectric sensor, or indirectly by analyzing satellite images.

Lux meterThe illuminance meter is a special equipment used to measure the intensity of light. In some specific environments, there are strict requirements for the illumination of light, such as the inspection of drugs by hand, there are strict requirements for the illuminance of light.

Related principles. Using germanium photocell as a probe, the current generated by the photocell is different due to the different intensity of light, and then the current is amplified by DC, and then the DC signal is turned into a digital signal with a direct reaction of light intensity through the digital-to-analog conversion circuit.

The determination of solar photometry requires the use of two astronomical quantities:

Solar flux constants: Represents the radiant energy received from the sun per unit time per unit area of space at the Earth's position.

Mean Earth-Sun Distancer: Represents the average distance between the Sun and the Earth. The common value of a constant is :

s = 1366 w/m^2

r = 149618753000 m
