LoRaWAN Smoke Detector

Build a Smart IoT Environment with Fabulous LoRaWAN Sensor

PLANET LS100-SMK IP20 LoRaWAN Smoke Detector is a crucial addition to any safety and security system, designed to detect smoke and high temperatures, providing early warnings to prevent potential fire hazards. Its smoke detection capability ensures rapid identification of smoke particles, crucial for early fire detection. Additionally, the high-temperature alarm activates when temperatures exceed 60°C, signaling potential overheating or fire. Equipped with an alarming bell, the LS-SMK promptly alerts occupants to take necessary action, enhancing safety measures in residential, commercial, and industrial environments. This multi-functional sensor ensures comprehensive fire safety, reducing risks and enhancing peace of mind.

LoRa and LoRaWAN Wireless Technology

LoRa is a low-power, wide area network (LPWAN) RF modulation technology. It standardizes LPWANs and enables extremely long-range data links. With a range of up to three miles (five kilometers) in urban areas and over 10 miles (15 kilometers) in rural areas (line of sight), LoRa is ideal for creating networks that require long-range or deep in-building communication. A key feature is its ultra-low power requirements, enabling the deployment of battery-operated devices that can last up to several years. Using the open LoRaWAN protocol in a star topology, it’s suitable for applications with numerous low-power devices collecting small amounts of data. The LS series is ideal for LoRa-enabled devices in the IoT system.

LoRaWAN-based Sensor

PLANET LoRaWAN LS100/LS200 series Sensor is fully compatible with standard LoRaWAN gateways like PLANET LCG-300 series, supporting the LoRaWAN class A. It is ideal for large-scale IoT applications, including building automation, smart metering, HVAC systems, agriculture, and more. The sensor facilitates the seamless integration of multiple sensors, making it a perfect choice for retrofitting legacy assets into IoT-enabled systems.
