| Abstract | ||||
| The aims of this research were to; 1- construct a simple alarm fire system to early warn for a fire in the agricultural facilities, 2- test the performance of the sensors used, mainly heat, light, and smoke sensors. Basically, these three sensors were connected to control panel and power supply. The control panel is to control the input data from sensors and the output data to the other units in the system. The response time of any fire sensor is the time from fire starting up to the moment that sensor senses the fire. It was considered to be the best factor to express the sensor performance. The performance of smoke sensor was mainly affected by the sensor height and smoke density where the response time increased when the sensor height increased while it decreased when smoke density (no. of mats) increased. The data analysis of this relationship showed a determination coefficient of 99.66%. For heat sensor, increasing the combustion temperature of material used for making fire reduced the response time of heat sensor, while increasing the heat sensor height increased the response time. The determination coefficient was found to be 99.2%. For the light sensor, the response sensitivity increased with increasing the light intensity at a specific distance. Thus, the light sensor must be placed at an appropriate distance to obtain a fast response. The determination coefficient this relationship was found to be 99.5%. | ||||
