| Summary: | Singapore experiences consistently high annual precipitation levels throughout the year, this leads to a humid climate and surface water accumulation. Wet floors can occur in various built environments due to factors like plumbing leaks, weather conditions, and equipment malfunctions. They can cause safety risks, property damage, and health concerns. Seeking practical solutions and preventive measures is crucial for creating safe and healthy indoor environments.
By harnessing the capabilities of modern technology, I have design four method to solve the problems. Thermal imaging and humidity sensors are not suitable for detecting wet floors due to water characteristics. Invisibility in wet-floor detection systems using IR transmitters and photodetectors enhances sensitivity, reliability, and adaptability. Laser and photoelectric detector systems offer high-precision, fast response, and non-contact monitoring. Therefore, a few experiments would be executed to showcase the viability and effectiveness of wet-floor detection systems by using Laser or IR and photoelectric detector systems.
Experiments showcase that a more minor incident angle is preferable if a higher output voltage is desired, the output voltage will increase with the decrease of the incident angle, except for Brewster's angle. As the water level rises, more photodetectors from different positions can catch their reflected laser beams or the IR beams, and the total voltages will increase accordingly. The LED-based alarm system illuminates in multiple colours and displays various water areas and depths.
Both methods have their own disadvantages, and further development is needed for future market use. The Laser Photodetector System is suitable for places with few people, like warehouses, to detect water leakage. The placement of the Laser and Photodetector is important, but the monitoring range is limited. The Infrared Photodetector System can be used in places with people walking around, like public toilets, to monitor water. The system has weak energy, but more photodetectors can be set up to increase its power. In conclusion, with increased power and problem-solving, the Wet-floor detection system can be accurate and useful in the mass market. It is hoped to solve problems caused by stagnant water in the future.
