Light Level Transmitter Low Power Light Level Sensor Manufacturer

The illuminance sensor is a sensor that converts the illuminance into an electrical signal, and the output value is measured in Lux. Light is an indispensable condition for photosynthesis;Under certain conditions, when the light intensity increases, the intensity of photosynthesis will also increase, but when the light intensity exceeds the limit, the stomata on the leaves of the plant will be closed, and the intensity of photosynthesis will decrease.Therefore, the use of illuminance sensors to control illuminance has become an important factor affecting crop yield.

Illumination sensor product introduction：

The illuminance sensor transmitter uses a high-sensitivity silicon blue photovoltaic detector as a sensor. Users can configure different measuring ranges according to different measuring places. It has the characteristics of wide measuring range, good linearity, good waterproofness, convenient installation, and suitable for long-distance transmission. It can be widely used in agricultural greenhouses, urban lighting and other places.

light level sensor is a sensor that converts the magnitude of light into an electrical signal, and the output value is measured in Lux.

Light is an indispensable condition for photosynthesis; under certain conditions, when the light intensity is enhanced, the intensity of photosynthesis will also be enhanced, but when the light intensity exceeds the limit, the stomata on the plant foliage will close and the intensity of photosynthesis will be reduced. Therefore, the use of light intensity sensors to control light intensity also becomes an important factor affecting crop yield.

Illuminance, which can be abbreviated as illuminance, is measured in "lux", or "lux" for short, and has the unit symbol "Lux".
