Light intensity illumination sensor Lux 0-5V/RS485/4-20mA for Greenhouse agriculture

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 intensity illumination sensor detection lighting intensity Lux Analog output 0-5V/RS485/4-20mA  for Greenhouse agriculture IOT Application

Illuminance sensors are a common detection device that is used in several industries. We see this device in many places, such as various automated weather stations and inside agricultural greenhouses.

How to use the illuminance sensor:

The illuminance sensor should be installed in an open area without any obstacle above the sensing surface. Adjust the sensor to a good horizontal position and then fix it firmly. It is better to fix the sensor firmly on the mounting bracket to reduce breakage or intermittent interruption on windy days.

Wall-mounted illuminance sensor installation: first drill holes in the wall, then put the expansion plug into the hole and screw the self-tapping screws into the expansion plug.

Louvered box type illuminance sensor installation method: Louvered box type illuminance sensor is generally used in outdoor weather stations, which can be installed directly on the weather station beam by means of a bracket or bending plate.
