‘IOT Multisensor Protection System Device’ is inspired by the observation of the manual method used for the detection of gas from smoke exposed by students who smoke, and fires caused by short circuit around Politeknik Sultan Azlan Shah. The objective is to take the initial safety precaution by knowing the gas leak at the workshop and avoid the occurrence of fires caused by the Distribution box. It is also to detect students whose smoking in the boy's student toilet at Politeknik. The project used IOT concept in detecting gas leaks, early fires, and cigarette smoke by application of flame sensor, gas sensor and smoke sensor. This sensor focused on Android users through the Blynk app. It is designed on a scale of close range from 3 to 50 meter. Gas sensor focused only on boy’s student toilet. The IOT Multisensor Protection System Device used Node MCU as a Microcontroller to allow wifi signals and to intermediate Microcontroller with smartphones through the application "Blynk”. As a result, the entire project was successfully created by facilitating lecturers to detect any short circuit in Distribution Box and cigarette smoke in the boy’s student toilet on a smartphone. Based on the results of the analysis and discussion have been concluded that the system developed has achieved the objectives that have been discussed.
