The system developed here is useful for measurement of waste gas (like Co2) remotely. This will helpful particularly for the environment department because many chimneys releases polluted gases now- a –days, which is a serious issues for Global warming. If any factory emits gas beyond some predefined specified limit, this system will send an alarm to operator’s mobile. For this, infrastructure of GSM has been used. Moreover we have implemented MODBUS-a serial communication protocol. And for local monitoring, a user friendly GUI has been developed so that required action can be taken immediately. Location of affected site is monitored by GPS module. Measured data can be sent to any mobile by just entering the mobile number in developed GUI. Controller MSP 430 is used for hardware development. As gas sensing element, MG811 is used. This system also monitors temperature of location and for that LM 335 is used.
