Agriculture Sensors List, Benefits of Agriculture Sensors
What advantages do agriculture sensors offer?
A sensor can detect data and turn it into an electrical signal or other needed information output. It follows rules to help with things like transmitting, processing, storing, displaying, recording, and controlling information. As IoT technology advances, sensors are used more widely in areas such as agriculture and industry.
In agriculture, farmers frequently employ sensors for air temperature and humidity, soil moisture, soil pH, light intensity, and carbon dioxide to gather data throughout different stages of crop development, such as seeding, growth, and harvesting. Farmers rely on agricultural conductivity and pH sensors to monitor and manage water and fertilizer levels effectively.The combined monitoring system monitors the blended fertilizer mixture.
What precisely are sensors used in agriculture?
Agricultural sensors primarily consist of plant information sensors and environmental sensors. We design plant information sensors to detect plants’ growth traits during their whole lifecycle, digitally process the growth indicators, and then assess the plants’ growth conditions.
Environmental sensors are mainly used to monitor and analyze the plant growth environment, including water, soil and air. They help us understand environmental changes and optimize the conditions for plant growth.
What constitutes a smart agriculture monitoring system?
Catalog of agricultural sensors
Sensors are fundamental. With the application of IoT technology, we can collect data on plants and animals and monitor their changes in real time.
In agricultural production, sensors play a vital role. Operations like fertilizing, spraying pesticides, and irrigating all rely on the data sensors gather. By keeping an eye on soil conditions, pest presence, humidity, and other plant-related data, we can figure out the optimal times for fertilization, spraying, and irrigation. This helps us avoid the waste of resources and damage to the environment that often occur in traditional agricultural methods.
1.Air temperature and humidity sensor
The sensor for measuring air temperature and humidity is great at monitoring changes in these conditions in agricultural planting areas. Its standard temperature monitoring range is from -40℃ to +80℃, and the humidity range is from 0%RH to 100%RH.
It has a wall-mounted design, making it easy to install in greenhouses or other shaded spots with good air circulation. When used outdoors, it can be installed in a solar radiation shield beside an agrometeorological station to collect weather data.
The coda sensor combines a Swiss-sourced temperature and humidity measurement unit with a built-in US industrial-grade microprocessor chip. This ensures accurate measurements and reliable communication.
2. Soil moisture sensor
The soil moisture sensor is a crucial tool in agriculture. It helps determine how much water crops can get. Too much or too little soil moisture can harm the healthy growth of plants above the ground. When the soil moisture is just right, it balances root water absorption and leaf transpiration, promoting the growth of crop roots.
The coda soil moisture sensor works by analyzing the soil’s dielectric constant to measure the percentage of volumetric soil moisture. This method of testing soil moisture meets current international standards. It can accurately and reliably show the real moisture content in different types of soil.
3. Soil pH Sensor
Keeping the right soil pH is very important for plants to grow strongly. The coda soil pH sensor works when its electrode (the sensor part) touches the soil directly. It uses the current produced by the redox reaction in a chemical process. This current value affects the data of different pH units, and the host device reads this data and shows it as numbers.
We make the sensor’s steel needle from a special alloy that resists corrosion from both acids and alkalis. We seal the casing completely with black flame-retardant epoxy resin, giving it an IP68 protection level.
4. Light Sensor
The light sensor consists of three primary components: a transmitter, a receiver, and a detection circuit, each constructed using electronic elements. Since it doesn’t involve the time needed for mechanical operations, it can measure light intensity rapidly. This sensor can quickly gauge light intensity within the range of 0 to 200,000 Lux, with a fast response.
In greenhouse farming, light sensors are useful. They enable farmers to precisely understand how much sunlight plants are getting, the light saturation point, and the light compensation point that are crucial for plant growth. With this information, farmers can adjust the lighting conditions manually to scientifically optimize the growth of crops, which in the end helps increase crop yields.
5. CO2 sensor
Crops constantly absorb CO₂ from the air for photosynthesis, and through this process, they produce nutrients vital for their growth and development. Studies have shown that a rise in the level of carbon dioxide in the atmosphere can greatly enhance plant photosynthesis.
The Coda carbon dioxide sensor employs cutting-edge infrared verification technology to accurately detect and measure CO₂ concentrations in the surrounding environment. It responds quickly and sensitively, solving the problems of limited lifespan and long-term drift that are common in traditional electrochemical sensors. Its standard measurement range is 0 to 5000ppm, and it has a temperature compensation function, which reduces the influence of external temperature changes.
6. Atmospheric Pressure Sensor
An atmospheric pressure sensor is adept at identifying changes in air pressure. Farmers can leverage this sensor to understand weather variations, such as drops in atmospheric pressure and changes in wind velocity, allowing them to efficiently execute disaster prevention and crop damage reduction strategies. This sentence is already in the active voice. It clearly shows the action of farmers (the subject) taking the initiative to harvest (the verb) mature crops in response to a predicted situation.
7.cipitation Gauge
A precipitation gauge is an instrument crafted to measure levels of rainfall. Rain and snow act as natural means for restoring soil moisture. The commonly utilized outdoor tipping bucket precipitation gauge provides accurate readings with minimal inaccuracies. When combined with an evaporation sensor, it facilitates a more comprehensive analysis of soil moisture. This device plays a crucial role in agricultural sensors by monitoring precipitation levels and their occurrence, providing indispensable data for optimizing irrigation strategies.
What benefits do agricultural sensors provide?
Irrigation system management:
By evaluating soil moisture, surrounding humidity, and meteorological data from weather stations, we can precisely measure soil moisture levels.This guarantees that the soil receives sufficient water in a timely manner. For example, we can incorporate the coda multi-layer soil sensor into irrigation systems to facilitate automated watering. We can manage the irrigation schedule and quantity through mobile device applications.
Introduce a system for pest and disease monitoring by strategically placing insect traps across the farmland and utilizing pesticide sprayers as needed to maintain crop health. Sensors can monitor temperature, humidity, air pressure, and other environmental factors in real-time, allowing for more efficient pest and disease control in the fields. For example, an insect monitoring system integrated with a weather sensor enables farmers to choose the right insecticide based on the collected data.
Optimize fertilizer management:
By evaluating the concentrations of dissolved oxygen, metal ions, and hydrogen ions in the soil, we can achieve a more precise understanding of soil conditions, identify the nutritional needs of crops, and enhance fertilizer management. For instance, employing a water-fertilizer machine to track soil nutrients and automatically dispense fertilizers can help farmers optimize fertilizer application and reduce waste.
Boost planting efficiency:
Sensors are vital in analyzing meteorological data, facilitating the scientific management and care of crops during their growth phases. For example, sensors that measure light intensity and temperature are advantageous in different weather and microclimate conditions, allowing for the comprehension and control of the crop growth environment, thereby maximizing production efficiency.
Promote sustainable growth:
Agricultural sensors enable farmers to accurately assess land utilization, reduce agricultural wastewater and emissions, diminish environmental impact, and contribute to sustainable development initiatives.
We mainly apply agricultural sensors in agricultural monitoring, particularly in water and fertilizer integration systems. These sensors are mainly used to monitor the conductivity, pH, and temperature of the mixed fertilizer solution. Following this, the data is displayed on an LCD screen and transmitted to the water and fertilizer management system for further processing.
The sensors for measuring agricultural conductivity and pH are equipped with integrated memory chips. They can store historical data for two days (for conductivity sensors) and three days (for pH sensors) respectively. They utilize high-precision analog-to-digital conversion and micro-processing technology, offering functions such as data collection and automatic temperature adjustment.
Unlike modern farming, traditional agriculture, which relies significantly on manual labor and uses basic farming tools and equipment, has increasingly shown its shortcomings. Contemporary agriculture harnesses the Internet of Things and sensor technology to provide accurate and timely information on crop development, facilitating the creation of scientific planting strategies, minimizing labor, improving crop varieties, and enhancing both the quality and yield of crops.
