All twelve sensors, each lit by what it watches for. Top row is stone, mossy cobblestone, emerald, end stone, netherrack and iron. Bottom row is wood, gold, prismarine, cobweb, hay bale and feather.

An upgraded GPS sensor in the wall watches the marked spot across the room and lights its lamp while a zombie stands there. The green box is the watched area.

Put a GPS in the slot, pick players, mobs or items, and type a name to narrow it down.

The upgraded sensor keeps a list of up to six entries, takes tags and can widen the area it watches.
