Large Sensor Hoop B

Large Sensor Hoop B is a sensor-based platform used to trigger nearby attached items when something passes through its hoop. It has two Level-2 attachment slots and six Level-1 reaction slots arranged in a ring around the base, along with four power sockets for connecting it to a power supply. When a Marble, Recreational Sphere, or a player passes through the hoop, anything mounted in the Level-1 slots around the ring is activated.

The platform is especially useful for building simple motion-based contraptions and automated displays. Powered devices placed on it will respond as long as the Large Sensor Hoop B has power, including lights such as the Work Light and Spotlight. Fireworks can also be triggered, and they launch from the attachment slots when activated.

Before Automation Update 002, this item was known as Large Hoop Platform B.
