A wireless distributed environmental mobile monitoring system based on Linux operating system been designed and tested. The proposed system consists of a Mobile Data-AcQuisition unit (Mobile-DAQ), ARM9 microcontroller board and two GSM modules. The mobile DAQ unit consists of Microcontroller (AT89S52) to which array of sensors (temperature sensor, moisture sensor, LDR (Light Dependent Resistor) and Gas sensor (CO, NO2 and CO2)) are connected. The mobile DAQ unit collects the data and this data is subsequently sent to the monitoring system via the GSM network.
