A Survey on Proactive, Active and Passive Fault Diagnosis Protocols for WSNs: Network Operation Perspective Although wireless sensor networks (WSNs) have been the object of research focus for the past two decades, fault diagnosis in these networks has received li... M Amjad,A Nabil,M Mithun,....
What are Passive Electronic Components? Passive electronic componentsare those that don’t have the ability to controlelectric currentby means of another electrical signal. Examples of passive electronic components are capacitors, resistors, inductors, transformers, and some diodes. These can be either T...
Sensitivity to soil moisture by active and passive microwave sensors The backscatter measured by a radar and the emission measured by a radiometer are both very sensitive to the moisture content m, of bare-soil surfaces. Vegetation cover complicates the scattering and emission processes, presumably ...
does not require any input device can complete its function -- is not smart. Resistance, capacitance, inductance, connectors are passive. The active device can control the voltage or current in a circuit or create switching action -- it is intelligent. Diode, triode, IC, crystal, sensors are...
Active sensorshave their own source of light or illumination. In particular, it actively sends a pulse and measures the backscatter reflected to the sensor. Butpassive sensorsmeasure reflected sunlight emitted from the sun. When the sun shines, passive sensors measure this energy. More on this lat...

View Passive Sensors Active (Hall Effect) AI-Tek has dedicated years of experience and time to designing and manufacturing Hall Effect sensors for Automotive, Military, Petro-Chem, Industrial, Rail, Power Generation and Marine and put that know-how into every sensor we make. ...
Active wheel-speed sensors require power to operate, whereas passive units do not. There are two types of active wheel-speed sensors: a Hall-effect sensor and a magneto-resistive sensor. A Hall-effect sensor requires either a toothed or magnetic ring to generate a voltage signal, whereas a ...
Active and Passive Electronic Componentsis an open access journal providing a forum for the science and technology of all types of electronic components, and publishes experimental and theoretical papers on topics such as transistors, hybrid circuits and sensors. ...
