Electronic sensors are built to generate electronic signals that can be measured, analyzed, and interpreted by other electronic devices. The interpretation of the sensed data provides the system with perceptive-type information that it may use to make decisions or take action based upon previously established programming. Sensation and perception provide empirical information that informs our experience of the external world and the reality of what is transpiring. Sensors located on electro-physical devices may be connected to the IoT. Electronic sensors may mimic human senses or may be radically different and unique in their own way. While the human hand can sense vibration happening in mechanical systems, oftentimes the electronic sensor is the best way to go because it is able to be put into a wider variety of applications and provide more precise information. For example, ADI makes high performance wide-bandwidth microelectromechanical systems (MEMS) as sensors. These MEMS may be deployed in evaluation and development efforts for a wide variety of vibration monitoring applications. For example, the Analog Devices ADXL355 Low Noise, Low Drift, Low Power 3-Axis MEMS Accelerometer, can be used for applications such as assessing bridge structures, landslide detection, and even machine health monitoring. Precision MEMS inertial sensors can capture dynamic motion accurately. The Analog Devices iSensor MEMS Inertial Measurement Units (IMU) provides many degrees of freedom in simulated aircraft motion for stabilization and navigation applications. The human nose can often easily smell when something is burning, like when I am cooking dinner. But often a human being is not present. Smoke, fire, aerosol, and electrochemical gas detection can be performed with greater sensitivity by a sensor than a human and without them necessarily being present. These sensors can readily distinguish different types of particles in the air or other media, minimizing false positive events. But sensors are more than just electronic bloodhounds. Sensors can also provide a means for electronics systems to have a perception of its surroundings, an analogy to human vision. The future of robots and autonomous vehicles is heavily connected with infrared sensors (IR). Infrared sensors employ wavelengths of light outside the visible spectrum in combination with a photodetector to allow direct position control of robots, enabling cable-less tethering to an operator, robot or drone swarms, and safety zones. Radio detection and ranging (Radar) is not just for airplanes and submarines. Radar employs the transmission and collection of electromagnetic radio waves. As sensors, radar technology helps provide excellent positioning information. In industry, it may be used for crane positioning, smart automation processes, and reliable collision avoidance. Because radar is capable of millimeter range precision in positioning it may be used in IoT to make industrial processes more efficient and safer. Good water is vital to a human being. Most large cities have good, clean, drinking water. But how does one know the water is good? Chemical sensors can be utilized. They can provide information regarding the chemical contents of the water, ensuring that proper health monitoring is performed. IoT chemical sensors attached to probes allow electronics to provide information, allowing humans to know whether the water is suitable for human consumption or if it should receive further treatment or be used elsewhere. In many applications, it is helpful to know with high precision the 7 IoT
