Sensors

A Sensor is a Hardmode mechanism that emits a signal under specific circumstances. Currently, there are 7 different types of sensors. There are 2 sub-categories of sensors. There are Logic Sensors, and there are Liquid Sensors.

There are 3 different Logic Sensors:
 * Logic Sensor(Day) which emits a signal during the day.
 * Logic Sensor(Night) which emits a signal at night.
 * Logic Sensor(Player Above) which emits a signal when a player is above it.

There are 4 different Liquid Sensors:
 * Liquid Sensor(Water) which emits a signal when submerged in water.
 * Liquid Sensor(Lava) which emits a signal when submerged in lava.
 * Liquid Sensor(Honey) which emits a signal when submerged in honey.
 * Liquid Sensor(Any) which emits a signal when submerged in any liquid.
