ME Threshold Level Emitter

It works like a reset-set latch. It turns the redstone signal off when the quantity of an item in the network is less than the lower threshold and turns it on when the quantity is greater than the upper threshold.

For example, suppose the lower threshold is set to 100 and the upper threshold is set to 150.

Initially, the network is empty, so the emitter is inactive.

As the quantity of the item increases past 150, the emitter sends a redstone signal.

When the quantity declines below 150, the emitter still sends a signal.

Finally, when the quantity falls below 100, the emitter turns off.
