1. A snow sensor, comprising:
a housing with a base and a post extending upward from the base;
a receiver positioned on the base; and
one or more emitters positioned on the post, configured to emit radiation downward toward the receiver;
wherein snow accumulated on the base accumulates between the one or more emitters and the receiver, and blocks at least some of the radiation from reaching the receiver; and
wherein the receiver is configured to receive the radiation that is not blocked and to report a numerical value that corresponds to the radiation received by the receiver.
