Fire Sensors Data Acquisition System and its Transmission by Using C8051 MCU

Ramadhani M. Ally | Zhang Jun ^[3]

Abstract: Fire sensors are the automatic components of the fire alarm system which include sensors for light, smoke, temperature, gas, pressure and humidity. In many buildings, fire alarm systems are equipped with wired or wireless sensors. In these systems, there are two data acquisition techniques used to collect information by using sensor detectors, namely, single-sensor detector and mult-sensor detector. Single sensor detector is vulnerable to interferences, such as dust, electromagnetic waves, water vapour, air, light, vibration and other environmental conditions. Then these fire parameters can be transmitted by using various techniques. In this proposed system we used RS232 protocol in Conjunction with C8051F040 Microcontroller to control and facilitate the said system automation. The data are taken and transmitted by cables up to the Microcontroller for transmission and further Processes.
