Established in October 2015, our company, acutely aware of the frequent occurrence of fires today, has developed a three-in-one sensor through the concerted efforts of our colleagues and industry-academia collaboration with four public and private universities. This sensor can effectively detect harmful gases that currently concern the general public, such as carbon monoxide, carbon dioxide, sulfur dioxide, methane, propane, butane, and other gases. In terms of fire safety, this product is a predictive alarm system. Furthermore, it utilizes mobile apps and GSM systems to enhance its integration with mobile phones. To better meet the public's demands for anti-theft and emergency assistance, our company has integrated the three functions of fire prevention, anti-theft, and emergency assistance into one, naming it the "Home Safety" (Ju-Jia-An) guardian system. We hope to safeguard and maintain the safety of life and property for our fellow countrymen.
