List of Agricultural Sensors and Their Advantages
Agricultural sensor station is a device that detects specific information. agriculture sensors changes this information into an electrical signal or another form. This process follows certain rules to help with transmitting, processing, storing, displaying, recording, and controlling information. Advancements in Internet of Things (IoT) technology lead industries, including agricultural, to utilize sensors increasingly.
Agricultural sensor station measure air temperature, humidity, soil moisture, soil pH, light intensity, and carbon dioxide levels. These sensors collect data during the entire crop growth process, from nursery stages to growth and harvest. Additionally, we use conductivity and pH sensors to monitor water and fertilizers. These sensors play a crucial role in integrated monitoring systems for mixed fertilizer solutions.
Agricultural Sensor Overview
Agricultural sensors can be categorized into plant information sensors and environmental sensors. Plant information sensors monitor how plants grow and develop. They process these biological signs digitally and analyze the conditions for plant growth. Environmental sensors monitor water, soil, and air conditions. They help track changes in the environment and support healthy plant growth. Commonly used agricultural sensors include those for temperature, humidity, pH, gas detection, biosensors, photoelectric detection, and pressure measurement.
Agricultural Sensors List
Agriculture sensors lay the groundwork for IoT applications that enable real-time tracking of plant and animal dynamics. In agriculture, sensors are indispensable for activities such as fertilization, spraying, and irrigation. By monitoring soil conditions, pests, and humidity, it becomes easier to decide when to fertilize, spray, or water. This helps avoid wasting resources and reduces the environmental impact often caused by traditional methods.
1. Temperature and Humidity Sensor
The temperature and humidity sensor measures changes in air temperature and humidity in farms. It works in temperatures from -40°C to +80°C and humidity levels from 0% to 100%. You can mount it on walls in greenhouses or areas with ample air circulation. For outdoor use, you can install it within a solar radiation shield for weather monitoring. Coda’s temperature and humidity sensor has a Swiss measurement unit. It also uses a US-made microprocessor chip. This ensures accurate measurements and stable communication.
2. Soil Moisture Sensor
Soil moisture sensors are crucial as they determine the water supply status of crops. Correct soil moisture levels ensure balanced root water absorption and leaf transpiration, promoting healthy crop growth. Coda’s soil moisture sensor uses the dielectric constant to measure soil moisture volume percentage. This method complies with international standards to accurately reflect moisture content in different soil types.
3. Soil pH Sensor
Proper soil pH is essential for normal crop development. The Coda soil pH sensor touches the soil with electrodes. This starts a redox reaction that creates a current. This current correlates with pH value data displayed numerically. The sensor has a corrosion-resistant electrode made from a special alloy. They seal it with flame-retardant epoxy resin for IP68 protection.
4.Light Sensor
The light sensor consists of a transmitter, receiver, and detection circuit, all made from electronic components. It works without mechanical time limits. It quickly measures light intensity from 0 to 200,000 Lux with a fast response time. In greenhouse agriculture, the sensor aids growers in accurately tracking plant sunlight exposure, identifying light saturation and compensation points. This data helps in manually controlling light preferences to optimize crop growth and achieve higher yields.
5.CO2 Sensor
Plants absorb CO2 from the air for photosynthesis, which is crucial for their nutrition and growth. Research shows that increased atmospheric CO2 boosts photosynthesis significantly.
Coda’s CO2 sensor uses advanced infrared technology for measuring environmental CO2 concentration. Its rapid, sensitive response circumvents the longevity and drift issues of traditional electrochemical sensors. It measures within a default range of 0-5000ppm and includes temperature compensation to minimize external influences.
6.Barometric Pressure Sensor
The barometric pressure sensor measures changes in air pressure. This helps farmers predict weather changes like drops in pressure or changes in wind speed. This foresight aids in effective disaster preparedness to minimize crop damage. For instance, predicted air pressure drops can prompt early harvesting of mature crops to prevent weather-related losses.
7.Rain Gauge
The rain gauge monitors precipitation levels and offers vital data for soil moisture replenishment through rainfall and snowfall. Commonly used tipping bucket rain gauges give accurate measurements with little error. They often work with evaporation sensors to analyze soil moisture correctly. It is a crucial tool for detecting precipitation patterns and assisting irrigation management in agricultural settings.
Benefits of Agricultural Sensors
Irrigation System Control: agriculture sensors can check soil moisture, humidity, and weather data from stations. This helps them find soil moisture levels accurately. This allows for timely water application using automated systems. One example is the Coda multi-layer soil sensor. It connects to irrigation systems. This helps control timing and water volume through mobile device programs.
Pest and Disease Monitoring
We use insect traps and pesticide sprayers with agriculture sensors. These tools help monitor temperature, humidity, and air pressure on farms. The monitoring happens in real time. This aids in efficient pest and disease management. For example, insect monitoring devices equipped with meteorological sensors enable growers to select suitable insecticides based on collected data.
Optimizing fertilizer management involves meticulously
Measuring soil components like dissolved oxygen, metal ions, and hydrogen ions. Knowing these elements helps us check the soil’s health and the nutrient needs of crops. This improves how we use fertilizer. Utilizing a water-fertilizer machine to track soil nutrients and automatically adjust fertilizer levels enables farmers to maximize efficiency and minimize waste.
Improve planting efficiency
Using agricultural sensor station to analyze meteorological data can improve planting efficiency and facilitate scientific crop management throughout their growth cycles. For example, sensors that measure light and temperature for plants can adjust to different weather and microclimates. This helps create the best growth environment for crops and improves production efficiency.
promote sustainable development
Using agricultural sensors helps promote sustainable development. These agriculture sensors allow for accurate land use calculations. They also reduce agricultural wastewater and emissions. This lowers the environmental impact and supports sustainability goals.
Agricultural sensor station are integral to monitoring within the integrated water and fertilizer system. Researchers mainly use them to measure the conductivity, pH levels, and temperature of fertilizer solutions after mixing. The system displays and uploads the data to the control system using LCD screens. These sensors have memory chips that can store data for up to three days. They use high-precision AD conversion and microchip processing technology. They also provide functions like data collection and automatic temperature adjustment.
Traditional agriculture, reliant on manual labor and basic tools, increasingly reveals its limitations compared to modern agriculture. The latter uses the Internet of Things and sensors to give accurate, timely data on crop growth. This helps with planning, saves labor, improves crop varieties, and boosts both quality and yield.
