    Product Description

    Description

    Illuminance  sensor is a practical product with a variety of light measurement range and signal output type with high sensitivity sensor and high precision linear amplification circuit.
    The sensor shell adopts wall installation or outdoor radiation shield shape design, with exquisite structure and beautiful appearance. It is a illumination measurement product with a wide-range of applications and high cost performance.

    Technical Description

    The ance is the unit that reflects the intensity of illumination, which is generally defined as the light flux to a unit area (m²). The unit of illumination is lumen (Lm), also known as Lux (Lux).
    The illumination degree of 1 unit is about 1 candle light at a distance of 1 meter. In China, in general, the illumination in sunny summer is 100,000 Lux (300,000 ~ 300,000 Lux), sunrise and sunset light intensity is 300 ~ 400 Lux, indoor fluorescent illumination is 30 ~ 200 Lux, night. 0.0 Lux ~ 0.03 Lux (bright moonlight), 0.003 ~ 0.0007 Lux (dark night)
