WARNING DEVICE OF GAS LEAKING

Abstract

This research was aimed to 1) design and construct warning device of gas leaking, 2) study the efficiency of warning device, 3) evaluate the satisfaction of the users of warning device of gas leaking. The research methodology was classified into 4 phases; 1) the study of problems of the LPG users in cooking, 2) the structure design of warning device, evaluated by 3 experts, 3) construct the warning device of gas leaking, evaluated by 3 experts, and 4) test the efficiency of warning device by 10 times recording the device operation, and study the satisfaction of 20 users of warning device who live in Muang, Sukhothai. The research instrument were the recording form of device efficiency and questionnaire. Data was analysed by mean and standard deviation. The results were as follows:

1. Warning device of gas leaking composed of two main parts; sensor and microcontroller.


2. The efficiency of warning device of gas leaking found that the settlement of gas cylinder at 3 meters, the gas leaking warning device warned at 15 seconds speed ​​alerts, and the settlement of gas cylinder at 5 meters, the warning device warned at 28.6 seconds speed ​​alerts.


3. The satisfaction of the users of warning device was at the level of “most”.
