AUTOMATIC SYSTEM FOR HAZARDOUS GAS, HUMAN DETECTION, TEMPERATURE MONITORING AND WATER LEVEL DETECTING IN COAL MINES USING GSM

Abstract

Fire Detectors play a very important role in Industries, Shops, Malls, Residential complexes,
parking areas, etc. They help in detecting fire or smoke at an early stage and can help in saving
lives. Commercial Fire detecting systems usually have an alarm signaling, with the help of a
buzzer or Siren. We have designed an IOT based Fire Alerting System using Temperature and a
smoke sensor which would not only signal the presence of fire in a particular premise but will
also send related information through IOT. Internet of Things (IoT) is basically the network of
„things‟ by which physical things can exchange data with the help of sensors, electronics,
software, and connectivity. These systems do not require any human interaction. In this Arduino
fire alarm system using temperature and smoke sensor using the IOT project, we can send LIVE
information like Temperature, Smoke Value detected by a particular device to the Fire
Department. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output
of secondary of 230/12V step down transformer.
