WebActive sensors are self-generating devices because their own properties change in response to an external effect producing for example, an output voltage of 1 to 10v DC or an output current such as 4 to 20mA DC. Active sensors can also produce signal amplification. A good example of an active sensor is an LVDT sensor or a strain gauge. WebMay 13, 2024 · The same applies to digital ICs: they should be placed over their own ground plane. Each type of component should only be routed over its own ground plane. A single ground plane can be separated into digital and analog sections while still being connected. The best place to connect the two planes is near the power source.
