Abstract

Sensors have become useful in many areas of our contemporary lives and also in industries, where they are largely used for measuring physical quantities for the purposes of analysis or control. The use of sensors is essential in areas such as industrial automation, robotics, environmental control, household appliances, agriculture, medicine, among other areas. Magnetic fields generated by the brain or heart are very useful in clinical diagnoses, so the magnetic signals produced by others Organs are also of great interest hence the need to condition the measured output of magnetic field sensors. The objective of this work is to realize a signal conditioning system for a magnetic field sensor based on MEMS technology. We achieve this by feeding sinusoidal signals to the magnetic field sensor using the Arduino system to obtain a linear response. The linear response is then conditioned by a MEMS signal conditioning system. We finally transmit the conditioned signal to a system receiver wirelessly, which will be visualized.
