Catalog of Agricultural Sensors, Benefits of Agricultural Sensors
Agricultural sensors are devices that collect data. They turn this data into electrical signals or other information. Sensors follow rules to send, process, store, display, record, and control information. As Internet of Things technology gets better, many areas, like agriculture and industry, use sensors more often.
Agricultural sensors measure air temperature, humidity, soil moisture, soil pH, light, and carbon dioxide levels. These sensors collect data at various stages of crop growth.
This includes planting, growing, and harvesting crops. Farmers use sensors to check water and fertilizer levels. The system monitors the mixed fertilizer solution.
What precisely are agricultural sensors?
Agricultural sensors include plant data sensors and environmental sensors. Researchers create plant sensors to see how plants grow. They track growth signs to check plant health.
Environmental sensors watch and analyze conditions that affect plant growth. They check water, soil, and air quality.
This helps monitor changes in the environment and ensures good conditions for growth. Right now, farmers often use sensors. These include temperature, humidity, pH, gas, biosensors, photoelectric, and pressure sensors.
What constitutes a smart agriculture monitoring system?List of agriculture sensors
Sensors are very important. They are the foundation of many systems. Using IoT technology helps gather data on plants and animals.
This allows us to monitor changes in real-time. Sensors play a key role in farming. They help collect data for tasks like fertilizing, spraying, and watering.
We can check soil conditions, pest presence, humidity, and other plant data. This helps us find the best times for fertilizing, spraying, and irrigating. This helps prevent wasting resources and harming the environment, which often happens with traditional methods.
1.Sensor for temperature and humidity
The sensor measures air temperature and humidity in farming areas. It can track changes in these conditions. The default range for temperature is -40℃ to +80℃. For humidity, the range is 0%RH to 100%RH.
The device has a wall-mounted casing. This lets users attach it in greenhouses or shaded areas with good air flow. For outdoor use, you can put it in a solar radiation shield next to a weather station for tracking conditions.
The CODA sensor uses a temperature and humidity measurement unit from Switzerland. It has a built-in microprocessor chip from the US. This ensures accurate measurements and reliable communication.
2. Soil moisture sensor
The soil moisture sensor is one of the most important sensors in agriculture. It helps determine how much water is available for crops. Too much or too little soil moisture can harm the healthy growth of crops above the ground.
Optimal soil moisture levels help roots take in water and leaves release it. This balance supports healthy root growth in crops. The CODA soil moisture sensor measures how much moisture is in the soil. It does this by checking the soil’s dielectric constant.
This method follows international standards. It gives clear and stable readings of moisture in different soil types.
3. Soil pH Sensor
Making sure the soil pH is right is important for healthy crop growth. The CODA soil pH sensor works by sensing when its electrode touches the soil. It uses the current created by the oxidation-reduction reaction in the chemical process.
The system uses the current value to show data from different pH units. The ammeter displays this data, and the host converts it. The report shows the results as numbers.
A manufacturer makes the steel needle from a special metal. This material is an anti-corrosion electrode. It resists damage from acid and alkali.
The manufacturer fully seals the casing with black flame-retardant epoxy resin, which boasts an IP68 protection rating.
4. Light Sensor
The light sensor has three parts: a transmitter, a receiver, and a detection circuit. All these parts are electronic. It does not consider how long mechanical operations take.
This sensor can quickly measure light intensity from 0 to 200,000 Lux. It also has a fast response time.
In greenhouse farming, light sensors help farmers see sunlight patterns. They can learn about the light saturation point and the light compensation point for plants. This information allows them to change light conditions manually. As a result, they can boost crop growth and get higher yields.
5. CO2 sensor
Crops take in CO2 from the air to help them grow. They use this process to make nutrients. Studies show that more carbon dioxide in the air boosts plant photosynthesis a lot.
The CODA carbon dioxide sensor uses new infrared technology to measure CO2 levels in the area. It responds quickly and accurately. This avoids the lifespan and drift issues of older electrochemical sensors.
It measures from 0 to 5000 ppm. It also includes temperature compensation to reduce the effects of outside temperature changes.
6. Barometric Pressure Sensor
A barometric pressure sensor detects changes in atmospheric pressure. Farmers can use this sensor to track weather changes. It helps them notice drops in air pressure and shifts in wind speed. This information helps farmers avoid disasters and lessen crop damage.
For example, if the weather forecast shows a drop in air pressure, farmers can harvest ripe crops early. This helps prevent losses from bad weather.
7. Rain Gauge
A rain gauge is a tool that measures how much it rains. Rain and snow help keep the soil moist. The common outdoor tipping bucket rain gauge gives accurate readings with little error.
When used with an evaporation sensor, it helps analyze soil moisture. This tool is important for farming. It tracks rainfall and how often it occurs. This provides key information for better irrigation management.
What advantages do agricultural sensors offer?
Irrigation system control: We can monitor soil moisture, humidity, and weather data from stations. This helps us understand how much water the soil needs. It makes sure the soil gets enough water when it needs it.
You can connect the CODA multi-layer soil sensor to irrigation systems. This lets you water automatically. You can use mobile apps to control when and how much water is used.
Implement pest and disease surveillance:
Set up insect traps and pesticide sprayers across the farmland. Sensors can track temperature, humidity, air pressure, and other environmental data in real-time. This helps improve pest and disease management in the fields.
For example, an insect monitoring device with a weather sensor helps growers choose the right insecticide using this data.
Enhance fertilizer management:
We can learn about soil conditions by checking the levels of:
– dissolved oxygen
– metal ions
– hydrogen ions This helps us understand what crops need for nutrition and how to manage fertilizers better.
For example, using a water-fertilizer system can help farmers check soil nutrients. It can also supply fertilizers automatically. This helps farmers use fertilizers better and reduce waste.
Enhance planting efficiency:
Sensors are important for understanding weather. They help us take care of crops as they grow.
For example, sensors that measure light and temperature help us in various weather situations. They help us understand and manage the environment for growing crops. This improves how efficiently we can produce food.
Encourage sustainable development:
Agricultural sensors help farmers measure land use accurately. They reduce agricultural wastewater and emissions. This lowers environmental impact and supports sustainable development efforts.
Farmers mainly use agricultural sensors for monitoring. This is especially true in systems that combine water and fertilizer. Researchers also use these sensors to check the conductivity, pH, and temperature of the fertilizer solution after mixing.
The system shows data on an LCD screen and sends it to the water and fertilizer management system. The agricultural conductivity and pH sensors have built-in memory chips.
They can store historical data for two or three days. These sensors use precise AD conversion and micro-processing technology. They offer functions like data collection and automatic temperature adjustment.
Traditional agriculture relies a lot on human labor and simple tools. Compared to modern farming, it has shown more weaknesses.
Modern farming uses the Internet of Things and sensors to get accurate data on crop growth. This helps create better planting plans, cuts down on labor, improves crop types, and boosts both quality and yield.
