List of Agricultural Sensors and Their Advantages
An agricultural sensor station is a device that detects important information. These sensors turn this information into electrical signals or other forms. This process follows rules to help transmit, process, store, display, record, and control information. Advances in Internet of Things (IoT) technology lead many industries, including agriculture, to use sensors more often.
Agricultural sensor stations measure air temperature, humidity, soil moisture, soil pH, light intensity, and carbon dioxide levels. These sensors gather data during the crop growth process, from nursery to harvest. We also use conductivity and pH sensors to test water and fertilizers. These sensors help monitor mixed fertilizer solutions.
Agricultural Sensor Overview
Agricultural sensors can be divided into two types: plant information sensors and environmental sensors. Plant information sensors track how plants grow. They collect data on plant health and analyze the conditions needed for growth.
Environmental sensors check the conditions of water, soil, and air. They help us notice changes in the environment. These sensors support healthy plant growth.
Common agricultural sensors measure temperature, humidity, pH, gas levels, and pressure. They also have biosensors and light detectors.
Agricultural Sensors List
Agriculture sensors are key for IoT applications that track plants and animals in real time. In farming, sensors are essential for tasks like fertilization, spraying, and irrigation. By checking soil conditions, pests, and humidity, farmers can better decide when to fertilize, spray, or water. This helps save resources and lowers the environmental impact of traditional methods.
1. Temperature and Humidity Sensor
The temperature and humidity sensor measures changes in air temperature and humidity on farms. It works in temperatures from -40°C to +80°C. It can also handle humidity levels from 0% to 100%.
You can put it on walls in greenhouses or places with good air flow. For outdoor use, install it in a solar radiation shield to monitor the weather.
Coda’s temperature and humidity sensor uses a Swiss measurement unit. It has a microprocessor chip made in the US. This helps provide accurate measurements and stable communication.
2. Soil Moisture Sensor
Soil moisture sensors are important because they show how much water crops have. The right moisture levels help roots take in water and leaves let it out. This balance helps crops grow healthy.
Coda’s soil moisture sensor measures how much moisture is in the soil. It uses the dielectric constant for this. This method follows international standards and shows moisture content accurately in different soil types.
3. Soil pH Sensor
Proper soil pH is important for healthy crop growth. The Coda soil pH sensor uses electrodes to touch the soil. This starts a reaction that creates a current. The current relates to the pH value shown as a number.
The sensor has an electrode that resists corrosion. It is made from a special alloy. They seal it with flame-retardant epoxy resin. This provides IP68 protection.
4.Light Sensor
The light sensor has three main parts: a transmitter, a receiver, and a detection circuit. All these parts are made from electronic components.
It quickly measures light intensity from 0 to 200,000 Lux. The sensor has a fast response time.
In greenhouse farming, sensors help farmers see how much sunlight plants receive. They can tell when there is too much or too little light. This information helps control light better. As a result, crops grow healthier and produce more.
5.CO2 Sensor
Plants take in CO2 from the air for photosynthesis. This process is important for their nutrition and growth. Studies show that more CO2 in the air greatly increases photosynthesis.
Coda’s CO2 sensor uses advanced infrared technology to measure CO2 levels in the environment. It responds quickly and accurately, avoiding the problems of older electrochemical sensors. The sensor measures CO2 in a range of 0-5000 ppm and has temperature compensation to reduce outside effects.
6.Barometric Pressure Sensor
The barometric pressure sensor measures air pressure changes. This helps farmers predict the weather, like drops in pressure or wind speed changes. With this knowledge, they can prepare for disasters and reduce crop damage.
For example, if air pressure is set to drop, farmers can pick their crops early. This helps avoid losses from bad weather.
7.Rain Gauge
The rain gauge measures how much rain falls. It gives important information about soil moisture from rain and snow.
Tipping bucket rain gauges are commonly used. They give accurate measurements with little error.
These gauges often work with evaporation sensors. This helps analyze soil moisture correctly.
Rain gauges are important for measuring rainfall. They also help with managing irrigation in farming.
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 manage when and how much water is used through mobile apps.
Pest and Disease Monitoring
We use insect traps and pesticide sprayers with sensors for farming. These tools help us check temperature, humidity, and air pressure on farms.
The monitoring takes place in real time. This helps with effective pest and disease management.
Insect monitoring devices have weather sensors. These devices help farmers choose the best insecticides. They make choices based on the data they collect.
Optimizing fertilizer management involves meticulously
Measuring soil components like dissolved oxygen, metal ions, and hydrogen ions is important. Knowing these elements helps us check soil health and the nutrient needs of crops. This improves our use of fertilizer.
A water-fertilizer machine can monitor soil nutrients and change fertilizer levels on its own. This helps farmers work better and cut down on waste.
Improve planting efficiency
Using agricultural sensor stations to analyze weather data can improve planting efficiency. They also help with crop management during growth cycles. For example, sensors that measure light and temperature can adapt to different weather and microclimates. This creates the best environment for crops and boosts production efficiency.
promote sustainable development
Using agricultural sensors helps support sustainable development. These sensors provide accurate land use calculations. They also cut down on agricultural wastewater and emissions. This reduces environmental impact and helps achieve sustainability goals.
Agricultural sensor stations are important for monitoring in the water and fertilizer system. Researchers use them to measure conductivity, pH levels, and temperature of fertilizer solutions after mixing.
The system shows and uploads data to the control system using LCD screens. These sensors have memory chips that store data for up to three days. They use precise AD conversion and microchip technology. They also offer features like data collection and automatic temperature adjustment.
Traditional farming relies on manual work and basic tools. It has its limits when compared to modern farming.
Modern farming uses the Internet of Things and sensors. These tools give accurate and timely data on crop growth. This information helps with planning and saves labor. It also improves crop types and boosts both quality and yield.
