In the evolving agricultural sector, technology plays a key role in optimizing crop yields, resource utilization and disease prevention. One such technological advancement is the integration of Internet of Things (IoT) devices, specifically IoT gateways, into soil environmental monitoring. In this article, we delve into the importance of IoT gateways and their impact on smart farming.
IoT gateways act as a bridge between local sensors and the cloud. It collects data from various sensors deployed in the field and transmits it to a central point or the cloud for analysis. In soil environment monitoring, IoT gateways play a vital role in capturing real-time data from soil sensors and making it available for decision-making.
Key parameters monitored by IoT sensors
1. Soil temperature:
-Soil temperature affects root growth, respiration and nutrient mineralization.
– IoT sensors estimate soil temperature by measuring air temperature and other factors, but the most accurate measurements involve buried probes.
– Surface soil temperature can be monitored using non-contact IoT sensors using infrared (IR) technology.
2. Soil moisture:
– Soil moisture content directly affects plant growth, photosynthesis and crop yield.
– Buried probe with electrodes for accurate soil moisture measurement.
– IoT sensors can monitor soil moisture at different depths, helping with precise irrigation and resource optimization.
3. Soil water potential:
-Soil water potential reflects the energy status of water in the soil.
– Understanding soil water potential helps farmers manage irrigation effectively.
– IoT sensors provide continuous monitoring and can adjust irrigation schedules in a timely manner.
4. Solar radiation:
– Solar radiation is essential for photosynthesis.
– IoT sensors measure photosynthetically active radiation (PAR), ultraviolet radiation and shortwave radiation.
– Accurate solar radiation data helps optimize crop growth and yield.
Advantages of IoT gateways in soil monitoring
1. Real-time monitoring:
– IoT gateway enables continuous data collection, allowing farmers to monitor soil conditions around the clock.
– Real-time insights enable timely intervention to prevent crop stress and yield loss.
2. Cost-effectiveness:
– By embedding IoT sensors into agricultural soil, farmers no longer need to collect data manually.
– Remote monitoring reduces labor costs and improves efficiency.
3. Precision agriculture:
– IoT gateways contribute to precision farming by providing accurate data to make informed decisions.
– Farmers can adjust irrigation, fertilization and other parameters based on real-time soil information.
