Precision farming/agriculture is about using electronics and communication technology to monitor the growth of crop and also provide water, fertilizers, and any resources for the growth and also protecting crop from diseases. Here in this article we are talking about a solution by a company in providing right amount of water for the crops using wireless control tech. Using soil moisture sensors and water valves, the right amount of water can be fed to plants by having wireless monitoring and control of flow of water throughout the agricultural farm land. The wireless solution provider Radiocrafts, is offering Sub-GHz wireless mesh solution calld RIIM to manage automatically smart irrigation system.
This new wireless system supports connectivity to devices where mobile network coverage is not available. By providing reliable communication, this system enables collection of moisture sensor data and also control valves.
The solution is embedded in a RF module which uses a wireless network without any license fees. The mesh network is self-forming, self-feeding and self optimising, and it covers wide area of 80 to 80 kms, with a communication distance range of 1400 meters between devices. A single router can control thousand devices.
RIIM Supports adoptive frequency agility for high throughput and maintains time synchronisation by also featuring faulting node detection.
The water valves are controlled using symmetrical communication, that means RIIM is designed to handle downlink and uplink communication efficiently and effectively. The system also supports Over the air filmware updates, without a person going into the agriculture farming field to update the software.
Most importantly the system can be driven by 2 AA batteries for two years, by having much of the electronic circuitry going in to sleep mode as soon as it does its job.
A RIIM node can stay on for 10 years powered by a CR2772 (870 mAh capacity coin cell battery) while sending 12 bytes every hour, 24 hours per day.
The system also supports to directly interface to any sensor/actuator used for soil moisture sensing, light sensing for photosynthesis, rain sensing, temperature and also wind sensing.
