在马来西亚高地支持可持续农业

农民们的主要关切是作物产量不稳定。尽管温室为作物生长提供了可控的环境，但却无法避免病虫害。此外，农民缺乏对农场土壤状态的了解，也会导致一些未来的困难。作物所施的肥料量通常由农民自行决定。这通常会导致用药过量或不足，直接影响到作物生长。人为错误对作物产量的影响最大，灌溉效率低下或不稳定以及施肥错误会对作物健康产生严重的负面影响。

In the past five years, farmers in the Cameron Highlands, which are located 250 kilometers from Kuala Lumpur, Malaysia, have taken the initiative to implement a simple monitoring system for their farms’ soil health. However, cost and connectivity presented a serious challenge for the farmers. Smarter solutions and machine-to-machine (M2M) services are often expensive and not available in rural areas. End users, typically the farmers themselves, are naturally very concerned with a solution’s power consumption, availability and reliability, as these factors directly affect the cost to deploy and operate these solutions. For the Cameron Highlands, the region’s various hills and valleys created additional challenges for service providers and reduced network signal strength. As a result, the farmers turned to solutions based on Semtech’s LoRa® devices and the LoRaWAN® protocol.

LoRaWAN Smart Agriculture in the Cameron Highlands

With the given challenges, Atilze Digital (Atilze), one of Malaysia’s leading artificial intelligence (AI) and Internet of Things (IoT) companies, chose LoRaWAN for the Cameron Highlands due to its proven feature set for long range, low power IoT. Due to its streamlined architecture, LoRaWAN-based devices are simple to deploy and easily integrated into existing infrastructure. Atilze leverages the LoRaWAN protocol to connect fields to the Cloud quickly and painlessly, enabling large-scale applications to be up and running in less than a week.

Atilze chose LoRa devices and the LoRaWAN protocol because it offered the following features suited to the smart agriculture use case:

• The LoRaWAN protocol is one of the leading open standards for low power wide area networking (LPWAN) technology, enabling consistent connectivity over 40 kilometers from a gateway.
• LoRaWAN-based solutions flexibly deploy with minimal additional infrastructure and immediately connect to the Cloud. Solutions are scalable by number of gateways, enabling farmers to cover large fields quickly and easily.
• Battery operated sensors remove the requirement for fixed power and enable battery lifetimes up to 10 years depending on the use case.
• The LoRaWAN standard encrypts all communication, and has security fundamentally built into the specification.

Deploying a Reliable Smart Agriculture Solution

In a recent success story, a partnership between Atilze and Tanahmu, a software provide for smart agriculture applications in Malaysia, empowered a change in traditional farming in the Cameron Highlands and throughout Malaysia. In the deployment, Atilze Digital provided the technology and Tanahmu created the smart farming platform. Atilze deployed LoRaWAN gateways at three strategic locations in the Cameron Highlands. These gateways provide network coverage approximately 18 to 20 kilometers in diameter to cover the farming communities of Habu, Bertam Valley and Sungai Ikan. Atilze plans to deploy more gateways and extend this coverage in the near future.

To date, the deployment has enabled several smart agriculture use cases featuring LoRa-enabled sensors. Currently, farmers in the community leverage LoRaWAN to monitor soil moisture, electrical conductivity (EC), soil pH, temperature, humidity, and weather. Additionally, Atilze designed a smart fertilization solution with LoRaWAN connectivity to monitor fields of chili peppers, an important cash crop in Malaysia. The solution helps farmers monitor which fertilizers are used, and leverages real-time data to optimize the fertilization schedule and amount used. Following deployment, farmers have seen a reduction of up to eight hours of labor per day, a reduction in the amount of fertilizer used by up to 30 percent, and an increased pepper yield of up to 20 to 30 percent.

More LoRaWAN Smart Agriculture Use Cases

From increasing crop yield and limiting fertilizer use, to tracking livestock health metrics in real time, LoRaWAN applications in agriculture reduce environmental impact, maximize yield and create a more sustainable planet. Smart agriculture use cases based on Semtech's LoRa devices and the LoRaWAN protocol have demonstrated significant improvements, such as up to a 50 percent water reduction for commercial farms.
