Agricultural sensor equipment and smart greenhouse

Overview

Smart agriculture is an advanced stage of agricultural production. It integrates the emerging Internet, mobile Internet, cloud computing and Internet of Things technologies. Mainly relying on various sensor nodes (environmental temperature and humidity, soil moisture, carbon dioxide, images, etc.) deployed in agricultural production sites and wireless communication networks to achieve intelligent perception, intelligent early warning, intelligent decision-making, intelligent analysis, and expert online guidance of the agricultural production environment . Provide precision planting, visual management, and intelligent decision-making for agricultural production. Today, let’s take a brief look at several agricultural sensor equipment commonly used in smart greenhouses.

Agricultural sensors commonly used in greenhouses

Changes in temperature and humidity in the greenhouse will directly affect the physiological effects of plants such as photosynthesis, respiration, and transpiration. Different plants and different growth stages of the same plant have different requirements on the temperature and humidity in the shed. Therefore, in the greenhouse environment monitoring system, the temperature and humidity sensor is an indispensable item. The temperature and humidity sensors in the greenhouse are generally divided into two types: air temperature and humidity sensors and soil temperature and humidity sensors. In order to more comprehensively monitor the temperature and humidity changes in the crop growth environment.

The intensity of light will affect the rate of photosynthesis of crops, which in turn affects the yield of crops. In the smart greenhouse planting, the light sensor monitors and records the light intensity information during the growth of the crops in the greenhouse through the light sensor and the photosensitive sensor. This can also be directly connected to related equipment such as supplemental light systems and sun shading systems. Automatically turn on related equipment when necessary. Provide suitable light conditions for crop growth, increase the rate of crop photosynthesis, and increase yield.
