S88 retro with 16 grounded inputs

S88 protocol retromodule with 16 inputs connected to ground, which allow connecting hall type and reed type sensors.

The use of halls is preferably recommended, as they are more sensitive, although it should be keep in mind that hall sensors only detect one type of magnet polarity (Only the North or only South polarity, depending on the position of the hall). On the other hand, the reed sensors can detect any polarity of the vehicle's magnet, but their sensitivity is lower.

The use of retromodules allows to inform the computer control software of which point of the road is being used by a vehicle, in this way it is possible to track the passage of vehicles, allowing to automate routes, detours, stops, etc...
