Soil Moisture Sensor System
Populations, food production, economic activity, and society’s affluence all contribute to an ever-increasing need for water. Climate warming is putting even greater strain on our water supplies. The need for water exceeds availability in many areas, especially during periods of restricted supply, such as drought, or during periods of high demand, such as the irrigation season.
This is not a new problem.
Multiple methods have already been used to improve farming processes. There are several new solutions that can be implemented accounting for local differences in soil drainage and evaporation; using precise dendrometers, which can measure changes in plant diameters as small as a few micrometers; and deploying sensors that monitor conditions for photosynthesis.
In both open fields and greenhouses, where microclimates are critical these methods can help. In some circumstances, gas sensors may also be of interest.
Subject to the flaws of the human mind
Droughts can be mitigated by using efficient irrigation procedures; more than one crop cycle per year may be achieved; and the overall efficiency of production resources can be greatly increased. Increasing the irrigated area while decreasing the strain on already-depleted water supplies is also an option.
Here’s a look at how to grow plants in a greenhouse as an illustration. Agronomists carry out ground sensing and vegetable assessments regularly during their check visits. Qualitative data is recorded on paper notes at this stage.
Afterward, the data is analyzed. The agronomist uses this data to make judgments and carry out operations on plants and fields. When they undertake activities (such as irrigation, seeding, and pesticide treatments), they must record them on paper before saving them to a computerized system. Using this program, a farm may keep track of everything from how plants are cared for to how they’re grown. Remote terminal devices with a computerized control system automate watering and temperature management.
Incorporating wireless soil moisture sensor systems into farming techniques
Irrigation scheduling can be activated by employing a soil moisture sensor, a well-known method. Soil moisture sensors have exploded in popularity when dielectric soil water was introduced. VWC (volumetric water content) and electrical conductivity (EC). are the two most important metrics to keep an eye on. Each plot, or at the very least each set of sprinklers or drippers, has a controller and sensor fitted for precise real-time watering control. A specific watering schedule is set and re-programmed for each controller on a regular basis.
A high number of sensors are needed in each irrigation zone to provide an accurate reading of soil moisture. Many controllers and sensors are involved, and thus far the costs of investing, installing wiring, maintenance, and data handling have been a barrier. As a result, producers have sought new, enhanced, and cost-effective monitoring and control systems.
Wireless sensor networks have therefore been implemented throughout the sector. Costs for both installation and management are much reduced—yet the end result for users is improved accuracy and responsiveness.
A wide range of LoRaWAN soil moisture sensor system options
Sensors using LoRaWAN technology have long been a popular choice for tracking and monitoring a wide variety of objects. We now have new possibilities for smart IoT agricultural solutions since we can employ sensors with long-lasting batteries.
The agricultural business is particularly interested in soil moisture, temperature, and electrical conductivity (EC). Sensors that transmit soil moisture, temperature, and electrical conductivity (EC) data wirelessly over LoRaWAN might considerably improve soil monitoring and data processing.
-
Soil moisture sensors: Determining the soil’s moisture level before irrigating a given region can save up to 40% of water, making irrigation more efficient.
-
Soil-temperature and ambient-temperature sensors: In addition to humidity measurements, these sensors can be used to prevent irrigation when temperatures would cause water to freeze—undesirable in many circumstances.
-
Soil electrical conductivity (EC): Knowing in advance the nutrient level in soil water helps configure irrigation and fertigation to deliver the best results for crops or plants.
This is how a LoRaWAN soil moisture sensor system application might operate:
-
Long-life battery sensors can be placed without wiring constraints. The precise positions depend on the field, crops, and the parts of the property the farmer wishes to monitor. Sensors can be easily relocated as needs change.
-
Sensor data is collected from the field using LoRaWAN gateways. Each sensor’s unique identifier is linked to its data. Data collection and processing are automated, eliminating error-prone manual recording.
-
Water and fertilizer requirements may be broken down by field area. The system determines how much water and nutrients to provide to each region to achieve optimal development.
-
The irrigation equipment then supplies the crops and plants with the appropriate amounts based on the processing system’s predefined zones.
Wireless sensors can considerably improve crop and plant growth in the farming business. Using a LoRaWAN soil moisture sensor system has the following advantages:
- Consumption of water is decreased.
- The yields of crops are boosted.
- You may set up tariffs based on your usage and keep track of it.
- The use of unauthorized water has been discovered.
Because they do not require battery replacement, the LoRaWAN soil moisture sensor system cuts sensor device investment and maintenance expenses. The farming business can benefit greatly from the use of these methods.
