Illumination sensor detection lighting intensity Lux for Greenhouse agriculture IOT

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.

Sensor technology is sought after by a wide range of agricultural workers. The following are a few of the sensors commonly used in smart agriculture.

Temperature and humidity sensor

It is currently the most widely used type of sensor in smart agriculture, widely used in greenhouses, soil, open-air environment, plant foliage, food and vegetable and fruit storage and other processes of temperature and humidity monitoring. Among them, wireless air temperature and humidity sensors are used to detect the temperature and humidity of the air in the agricultural environment.

It is usually installed in the greenhouse greenhouse or livestock barn in the shade of air circulation. Soil temperature and humidity sensors are installed in the soil at the roots of crops, and the depth of the sensors is determined according to the depth of the root system of the crop, usually 2-4 sensors per greenhouse or greenhouse length, to detect the soil temperature and moisture content and changes in the process of crop growth and development, so as to facilitate timely and appropriate star watering.

Illumination sensor

Illuminance is the amount of luminous flux per unit area on the illuminated surface of an object. It is especially suitable for agricultural greenhouses to detect whether the light intensity required for crop growth reaches the optimal growth condition to decide whether the light needs to be supplemented or shaded.

Wind Speed Sensor

The wind speed sensor is mainly used outdoors for the detection and collection of meteorological wind speed, and shade nets and rolled films are commonly used in greenhouses for shading and heat preservation. The system will calculate and process the wind speed according to the wind speed information sent back to the system, so as to retrieve the shade net and rolled film in time under the high wind speed, and prevent the damage of shade net and rolled film by high wind.
