Semiconducting metal oxide sensors, such as tin dioxide (SnO2) and tungsten oxide (WO3), have been extensively studied for C3H8 gas sensing. These sensors operate based on the principle of chemiresistive sensing, where the electrical resistance changes when exposed to C3H8 gas. Recent innovations in materials engineering and nanostructuring techniques have improved the sensitivity and response time of these sensors, making them highly effective for propane gas detection.

Optical Fiber Sensors:
Optical fiber sensors offer a unique approach to C3H8 gas sensing. These sensors utilize the interaction between C3H8 molecules and specific coatings on optical fibers to generate measurable changes in light transmission. By monitoring the variations in light intensity or wavelength, optical fiber sensors can detect and quantify propane gas leaks accurately. Their compact size, immunity to electromagnetic interference, and ability to cover large areas make them suitable for diverse applications.

Wireless Sensor Networks (WSNs):
Integrating C3H8 gas sensors into wireless sensor networks (WSNs) has revolutionized real-time monitoring and early detection of propane gas leaks. WSNs consist of interconnected sensor nodes that communicate wirelessly, providing continuous data on gas concentrations. This enables prompt identification of leaks, allowing for timely intervention and preventive measures. With the advancement of Internet of Things (IoT) technology, WSNs can provide remote monitoring and control capabilities for enhanced safety.
