LoRaWAN sensors for smart industry are becoming a key component in modern industrial facilities aiming for higher efficiency, lower costs, and better sustainability. Through a wide range of monitoring and optimization solutions, the French manufacturer Watteco brings innovations that combine IoT technology with advanced features for resource analysis and management. Application of communication technology LoRaWAN enables reliable and secure wireless communication over long distances with extremely low energy consumption – battery-powered sensors can operate for up to 15 years. Thanks to excellent radio signal penetration within buildings, this technology is ideal for complex industrial environments. Additionally, AES encryption, adaptive data rate, and support for thousands of devices on the same network make LoRaWAN a scalable and secure solution for Industry 4.0. Key devices and their applications BOB Assistant: An advanced device for predictive machine maintenance that measures vibrations and temperatures. It alerts to potential failures before they occur, reducing maintenance costs by up to 20% and increasing operational efficiency. TORAN’O: A sensor for monitoring door and window openings/closings, especially useful in security management and access control in high-risk facilities, including explosive zones (ATEX). Triphas’O: Measures electrical energy consumption in three-phase systems in real-time, detects losses, and enables energy savings up to 30%, which is crucial for energy-intensive sectors. IN’O and Lev’O+: Level sensors for precise monitoring of liquid levels, ideal for industries relying on tanks, pipelines, and fluid transfer or storage, without direct contact with the medium. Press’O+ and Clos’O: Monitor pressure and valve status, providing data for safer and more efficient process management. Smart Plug and Intens’O: Track and analyze device energy consumption in real-time, enabling better consumption control and automation. Industrial plants are already seeing significant benefits from these solutions – from drastically reduced downtime and longer equipment lifespan to easier compliance with environmental regulations. Automated monitoring and reporting allow timely responses and strategic resource planning. Users in heavy industry emphasize that robust, multifunctional sensors have greatly simplified machine upgrades, enabling seamless integration into existing systems without operational interruptions. LoRaWAN sensors form the foundation of modern industrial transformation. Their reliability, flexibility, and compatibility with existing systems enable smart resource management, increase safety, and contribute to business sustainability. In the digital industry era, Watteco solutions bring a new level of control, efficiency, and environmental responsibility – setting technological standards for the future of smart industry.
