Wireless gas monitoring technology delivers cost-effective precision and flexibility

Monitoring gas levels across industrial or environmental sites can be challenging, especially when running cables is expensive or impractical. The iSens wireless gas sensor from Sensotran addresses this challenge by combining flexibility, reliability, and easy deployment.

Using LoRa wireless technology, iSens transmits gas measurements directly to a central monitoring system, enabling sensors to be installed across large facilities, storage yards, wastewater plants, and infrastructure projects without extensive wiring.

The platform supports a wide range of sensors to match different monitoring needs. Electrochemical sensors can detect oxygen and toxic gases, catalytic and infrared sensors monitor flammable gases, infrared sensors track carbon dioxide, and PID sensors measure volatile organic compounds (VOCs). This versatility allows each system to be tailored to the specific gases and site conditions.

Installation is straightforward. The sensors are designed to be positioned right at the measurement point, reducing the need for additional infrastructure. When using electrochemical sensors, internal batteries provide up to two years of operation, minimising maintenance.

Wireless communication is handled via a bidirectional LoRa modem. In ideal line-of-sight conditions, signals can reach up to 7 km, though in typical industrial environments, ranges of 1 km or less are common. Multiple sensors connect to the GasVisor LoRa control unit, which monitors system status, alerts operators to low batteries or signal loss, and ensures the network remains under control.

Built for demanding environments, the iSens platform features an IP65 rating and operates from −20 °C to +50 °C, with humidity up to 95% RH.

By combining wireless flexibility, adaptable sensing, and long battery life, the iSens platform offers a practical, efficient solution for distributed gas monitoring in industrial and environmental applications, helping teams deploy sensors quickly while keeping maintenance simple.
