A Wireless Approach to Real Time Remote Monitoring System examining Environmental Parameters Using Feasibility of a GSM Module

This paper report proposes a wireless approach for monitoring a remote area which has a large area and therefore becomes difficult to be managed by an individual due to lack of any information. Using GSM module, it is a very effective and accurate techniques to transmit useful information. That information contains the parameters such as temperature and humidity of the medium. For sensing the temperature a thermistor has been used, which is a low cost device having temperature range -110°F to 500°F. This is one of the most sensitive sensors and exhibits a large range of change in the temperature. HR202, is an organic macromolecule material, which is used for sensing humidity of the medium. A cell phone is needed at the receiver´s end which is used to get the value of the parameters. For controlling the system a microcontroller has been used with which every sensor and GSM module has been connected. Whenever, in the real time, the value of a parameter changes, a message is automatically sent to the predefined numbers containing the value of the parameters. One can also receive the details of parameters such as temperature and humidity by just giving a call to the GSM in which a SIM card has been inserted. The ability to have someone monitor the parameters around the clock is the best thing that this system can do. This technology focuses on the delivery of a safe, effective, and efficient, agriculture based remote monitoring system.
