Product Description：
The illumination sensor is a practical product with a variety of illumination measurement ranges and signal output types that uses a highly sensitive photosensitive detector and a high-precision linear amplification circuit. It is rigorously tested and accurately produced.
The sensor housing is designed in the shape of wall-mounted installation or outdoor radiation shield, with exquisite structure and beautiful appearance. It is an illumination measurement product with wide application range and high cost performance.
Product features：
(1) Using imported sensor design, the measurement is more accurate and reliable.
(2) High cost performance and wide voltage design.
(3) Digital linearization correction, high precision and high stability.
(4) Use real sunlight calibration to minimize the impact of the light source.
(5) Flexible installation and easy to use.
(6) Small size, light weight, and anti-vibration.
(7) It can be made into a variety of shapes to meet the needs of different customers.
Scope of application：
It is widely used in meteorological stations, agriculture, forestry, greenhouses, breeding, construction, laboratories, urban lighting and other fields that need to monitor light intensity.
Technical Description：
Illuminance is a unit that reflects the intensity of light. It is generally defined as the luminous flux that shines on a unit area (m²). The unit of illuminance is lumen per square meter (Lm), also known as lux.
One unit of illumination is about the brightness of one candlelight at a distance of one meter. In my country, under normal circumstances, the illumination under strong sunlight on a sunny day in summer is 100,000 Lux (300,000 Lux to 300,000 Lux), the illumination on a cloudy day is 10,000 Lux, the illumination intensity at sunrise and sunset is 300 to 400 Lux, the illumination of indoor fluorescent lamps is 30 to 200 Lux, and the illumination at night is 0.3 to 0.03 Lux (under bright moonlight) and 0.003 to 0.0007 Lux (on a dark night).
