Whenever a lighting application, such as street lighting for example, requires an elevated number of LEDs, there are basically two solutions: connect all the diodes in series or place several strings in parallel.
By adding air quality sensors to smart building systems, engineers can implement early warning of the buildup of hazardous gasses and chemicals, but commercial air quality sensors lack the integrated capabilities required to join a smart building network.
To explain how isolation amplifiers work and how to apply them effectively, this article will describe a typical scenario where isolation is required before discussing three common isolation methods; transformer coupling, optical coupling, and capacitive coupling.
Current sensing is key to extending battery life, preventing overcurrent conditions, monitoring ground faults, and optimizing control of power sources. The problem is making these measurements accurately in spite of high common mode voltages.
