Why LoRaWAN Relays Are Ideal for Smart Agriculture

In smart farming, connectivity is everything. Sensors measure soil conditions, gateways collect and transmit data, and relays act as the hands of the system — turning pumps, valves, and devices on or off based on real-time needs. The challenge is how to connect these components reliably over long distances and with minimal energy use.

LoRaWAN relays by Daviteq are seamlessly integrated into modern smart irrigation systems, enhancing connectivity and efficiency.

That’s where LoRaWAN (Long Range Wide Area Network) technology makes a real difference. It provides a secure, long-range, and low-power communication layer that’s perfect for farms, greenhouses, and irrigation networks. When combined with wireless relays, it enables complete remote control of field equipment without wiring or complex infrastructure. Here’s why LoRaWAN relays are becoming essential in agricultural automation:

• Long-Range Coverage: LoRaWAN signals can travel up to several kilometers, allowing a single gateway to control pumps, valves, and actuators across large farms. This eliminates the need for buried control cables or signal repeaters.

• Ultra-Low Power Consumption: Wireless relays like Daviteq’s WSLRW-LRO and WSLRW-LSV operate for years on small batteries, making them ideal for remote irrigation zones where external power isn’t available.

• Reliable and Secure Communication: LoRaWAN uses adaptive data rates and AES-128 encryption, ensuring stable and secure switching commands even in challenging environments like industrial farms or dense greenhouse networks.

• Easy Integration with IoT Platforms: Daviteq’s relays connect seamlessly to LoRaWAN gateways and cloud-based IoT systems such as Globiots, where users can schedule irrigation, monitor equipment status, or automate control logic.

• Scalable and Cost-Effective: A single LoRaWAN network can support hundreds of sensors and relays, making it easy to scale from small farms to regional water management systems — without adding new wiring or infrastructure.

With these advantages, LoRaWAN relays have become the backbone of smart irrigation systems, allowing farmers to optimize water use, reduce manual work, and extend automation to every corner of the field — all with reliable long-range connectivity.
