This paper proposes a new mobile monitoring system for environmental awareness toward wireless sensor networks (WSNs). This system assists Android OS mobile users to observe an environmental behavior, and then to alert for a sudden change with configured thresholds. The paper describes the instrument and component of the key design of the system. In addition, a new efficient technique to transmit environmental sensor data over WSNs is introduced by a design of flexible bit pattern to identify the type of sensor data. For performance evaluation, compared to a traditional transmission technique, analytical and practical - using Tmote Sky - results show the reduction of power consumption due to the number of aggregated bytes and transmissions.
