Smart Watering and Fertilizing System

Soil sensor is capable of measuring soil temperature, moisture, total salt content (conductivity), soil PH, nitrogen, phosphorus and potassium. 

The soil sensor plays a crucial role in smart farming by providing real-time data that helps farmers make informed decisions about irrigation, fertilization, and overall crop management.

A weather station for smart farming is a critical component that provides real-time and historical weather data relevant to agricultural operations. It consists of various sensors and instruments designed to measure key meteorological parameters that influence crop growth and farm management decisions.

In smart farming, understanding and utilizing photosynthetic active radiation (PAR) and spectral information are crucial for optimizing crop growth and productivity. PAR refers to the spectral range of solar radiation that plants use for photosynthesis. It typically ranges from 400 to 700 nanometers (nm) and corresponds roughly to the wavelengths of visible light. PAR is essential for plant growth because it drives photosynthesis, the process by which plants convert light energy into chemical energy (sugars) that fuels growth and development. PAR sensors measure the intensity of light within the range that plants can use for photosynthesis. This helps farmers understand how much light plants are receiving, which is crucial for determining optimal planting densities, managing canopy growth, and optimizing light exposure for maximum photosynthetic efficiency. Spectral information refers to the distribution of electromagnetic radiation (light) across different wavelengths. Different wavelengths of light have varying effects on plant physiology and growth. Remote sensing technologies, such as hyperspectral imaging and spectroradiometers, capture spectral data across multiple wavelengths beyond the visible range (UV, NIR, SWIR).

The humidity of the plant leaf surface is very important for the growth of the leaves. The leaf temperature and humidity can better reflect the growth index of the real leaf. The leaf surface temperature and humidity sensor accurately measure the temperature and humidity of the leaf surface to detect the growth environment of plant leaves and achieve the purpose of preventing pests and diseases. The shape of the sensor adopts the shape design of the blade, which simulates the real characteristics of the leaf surface, so it can more accurately reflect the situation of the leaf surface environment. The leaf surface temperature and humidity sensor measure the residual of water or ice crystals of the leaf by detecting the change of the dielectric constant on the leaf.
