Intensity of illumination by light part of the rod, How about garden light photovoltaic box) Have a good

Actually photocell is always linked with external circuit, header, and external circuit, the temperature coefficient of resistance also to have certain the meter, it is possible through the choice of external header, makes the photocell to temperature dependence can be partially compensating. So the



actually photocell is always used with open circuit, headers, and the external circuit, temperature coefficient of resistance also to have certain the meter The temperature coefficient of a physical properties of materials with the temperature change and the rate of change. 】 , it is possible through the header/choice, makes the photocell to temperature dependence can be partially compensating. So make a temperature correction should be the whole luxmeter 【 (illuminance meter Or the lux meter) Is a kind of special measure instrument of illuminance. 】 Unified as a whole to consider, Y-axis is thermometer side illuminance value and the actual illumination than that transverse temperature for the environment. Thus it is concluded that the introduction. When actual child when the environment temperature measurement and calibration of temperature difference is not very big, and for measuring accuracy is not high, don't consider the result of the test for temperature correction. But if use silicon photocell 【 Silicon photocell directly converts light energy into electrical energy is a kind of semiconductor devices. 】 Because of its current output is strongly dependent on temperature. In addition, in wet air must be revised its correction coefficient manufacturers generally have been given. Gas, light turtle pond have a tendency to absorb moisture, photocell may damage, deterioration, and even completely lose the light sensitivity. So the intensity of illumination rod by light section ( Photovoltaic box) Have good sealing performance, in order to prolong the service life of cell, storage cell should be paid attention to more don't in the moist environment. Moreover, because of the sensitivity of each point on the cell surface is usually different, so the measurement of intensity of illumination should make light as far as possible even when the entire cell surface, otherwise will also introduce the measuring error.
