GSM Based Multi Node Pressure Sensor in Barometric Altimeter - A Survey
The authors' proposed project was mainly based on GSM networks and controller. Barometer is a well-organized tool for determining atmospheric pressure. The altimeter is a tool which calculates the vertical distance in accordance with a reference level. The barometric altimeter, computes the altitude according to the atmospheric pressure. Accuracy and size are the major issues in altimetry. MEMS based Barometric Altimeter is implemented using the following two terminals of embedded barometer Module. Even though the size of the MEMS based Barometric Altimeter is reduced, it provides more accuracy.
