How is the solar thermometer is absorb sunlight?

Solar thermometer readings is convenient, long battery life, get a lot of industries. Compared with the traditional pointer thermometer, he can directly with digital display temperature, high precision, easy to use, the display is straightforward enough. He can let people intuitively understand how much he'd like to know what the temperature is. The working principle of solar thermometer is the use of solar energy and the cable sensors provide accurate temperature indicator. Do you know how it is to receive the sunlight? In this DST2002S solar thermometer, for example, it has a bright LCD display, easy reading, display here is a black chip, it is a solar wafer, is to rely on it to receive the sun, when light levels high 100 lux will show that the temperature of the object to be tested; When the light levels drop, with a backup battery to provide power to continue to display circuit. The power switch ( OFF/ON） Equipped can save electricity effect, at the same time also more environmentally friendly.
