Abstract
To monitor the amount of gas (particularly Co2) from any factory site, a design has been developed which measures and monitors the amount and pressure of Co2 and also the temperature of that particular location. This will be helpful if any factory or chimney releases polluted gas like Co2 above some specified limit, which seriously affects people's health. When level of Co2 exceeds certain predefined level, this system will send an alarm to operator’s mobile. For this, existing infrastructure of GSM have been used. GPS module will be used for locating exact position of plant. In this system, controller MSP 430, gas sensor MG811 and temperature sensor LM 335 are used as core elements. In this area until now, the work done is remote measurement of CO2 and that data was sent by GSM. The GPS was effectively used to locate the position. Here MODBUS is used which is serial communication protocol which will continuously update the value on local monitoring station also. So that required actions can be taken immediately if it is required. Moreover another parameter-temperature is also measured and updated. MODBUS is now-a-days a better option over conventional low speed wireless channels. The precision and accuracy of recorded results of measured Co2 and position from GPS have been increased. The controller used here can give response to 247 different devices.
