The Amazonia-1 is the first Earth observation satellite totally developed in Brazil. Its mission is to detect and monitor deforestation in the Amazon.
XENON1T is an experiment created to detect dark matter and hypothetical particles. Recently registered unexplainable events.
Was developed a high efficiency photodetector based in quantum dots.
Today are shown how Hall effect works, a magnetic sensor using this phenomena and how o use it in projects with Arduino.
MEMS are abbreviation of Micro Electro-Mechanical Systems, are miniaturized electromechanical machines. An introduction to MEMS and some of its applications are today’s subject.
This post’s subject is Kalman filter. It is a very useful tool in control systems, where there is no certainty in system’s information.
This is the second part explaining various types of antennas. Reflecting antennas are this post’s subject. Reflectors serve to increase directivity.
With infrared (IR) sensors, can build a line follower robot. The construction and operation of this type is the post’s subject.
This post’s subject are the infrared sensors. It is possible to build one or buy a complete, and make many electronic and robotic projects.
