Abstract

Accidental leaks of high concentrations of ammonia pose significant risks including fatalities and severe injuries. In Malaysia, numerous incidents have been reported due to ammonia leakage and exposure. Therefore, an effective detection and warning systems is urgently needed. This paper reported a system than can trigger an alarm when ammonia gas was detected and reach certain concentration in the working area. The alarm system was equipped with a self-developed optical sensor which has excellent accuracy with an averaged error of 1.22 %, fast response and recovery time which are 3 s and 4 s respectively. The sensor also does not depend on the flowrate of the detected gas. The design includes optical fiber integration, allowing the placement of the detector and light source at safe locations. Additionally, a LabVIEW-based interface was developed to monitor and display real-time ammonia concentrations. This project successfully developed a system capable of detecting ammonia leakage and triggering an alarm within 3 sec.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
