Gas Detection II


Project Details

Goal: The aim of the Gas detection project is to enable the existing Wireless Sensor Network with one LCD display that shows messages alerting the users about the danger of the room atmosphere and with a keypad that allows the users to change application parameters on runtime The initial set of functional requirements considered for this project follows:

  • Display an alarm message indicating danger when the gas levels rise above a certain limit.
  • Display an informative message indicating the average gas level in the room.
  • Use the keypad to change application parameters on runtime.

In order to implement these requirements, some technical requirements need to be taken in consideration. The main technical requirements identified are the following:

  • The application must not take more than 2 seconds to show the alarm message after the gas level rise is identified.
  • All sensor nodes must send a message to the remote node immediately after the detection of a high amount of gas.
  • The LCD display needs to be powered with 5 Volts DC (the 2 AA batteries of the Motes can’t provide 5 V, the remote node has to be equipped with an extra battery?).
