Hydroponics water quality monitoring

    Hydroponics is a new type of soilless plant cultivation method, also known as nutrient solution culture. Its core is to directly immerse the roots of plants in nutrient solution, and use nutrient solution instead of soil to provide plants with water, nutrients, oxygen and other growth factors, so that plants can grow normally. Therefore, hydroponic water quality monitoring is the key to the success of hydroponics.

Hydroponics water quality monitoring system

    The water quality meter monitors the temperature, pH, conductivity, dissolved oxygen and other water quality parameters of the nutrient solution in the entire storage tank, and transmits the real-time water quality to the back-end monitoring system through RS485, or uploads the data to the cloud platform through the wireless acquisition module to achieve remote real-time management and monitoring. While saving costs, the nutrient solution is automatically supplied to ensure that the proportion of each nutrient element in the hydroponic nutrient solution is balanced, suitable for plant growth and development, and can be effectively absorbed and utilized by plants, so as to ensure that the hydroponic plants on the cultivation bed are always in the best growth and development state.

1. pH: The pH of the nutrient solution should be appropriate to facilitate the absorption and utilization of nutrients by plants. The pH should generally be controlled at 6-6.9 pH.

2. Dissolved oxygen: Plants need to absorb oxygen for normal growth and metabolism, and the water quality of the nutrient solution is also related to dissolved oxygen. Generally, dissolved oxygen is controlled at 4-5 mg/L.

3. Temperature: The appropriate temperature range can promote the root system of plants to absorb nutrients, improve nutrient utilization, accelerate growth, and increase yield and quality. Generally, the temperature needs to be controlled at 18-25℃.

4. Conductivity: The conductivity reflects the nutrient concentration in the nutrient solution. Appropriate conductivity can ensure proper nutrient supply and promote healthy growth and development of plants. Generally, the conductivity should be controlled at 2000-3000us/cm.
