1. A moisture sensor comprising:
- a housing adapted to mount onto a tree stem,a probe attached to the housing and adapted to detect water levels in a tree stand, the probe detects the conductivity of water to determine the water level,a conductive rod with insulators at each opposing end wherein the probe isseparated by one insulator at a first end of the conductive rod and the other end of the conductive rod is inserted into the housing,a PC board within the housing for determining water levels in the tree stand, a LED indicator adapted to provide a visual signal when water levels are below a threshold in the tree stand, anda speaker adapted to provide an audio signal when water levels are below the threshold in the tree stand,wherein the LED indicator signals the visual alert and the speaker signals the audio alert when the probe detects that the water level is below a threshold,wherein the probe detects the conductivity of water to determine the water level,wherein the probe comprises a copper wire connected at one end to the PC board, and an opposing end capped by a conductive shield, andfurther including a silicone insulator on the other end of the conductive rod adapted to provide a water-tight seal between the conductive rod and the housing.

Abstract
A moisture sensor providing a visual and audio alert when a tree needs to be watered. The moisture sensor may be mounted onto Christmas trees to detect when water levels are low in the tree stand. The moisture sensor comprises a housing and a probe attached to the housing. The housing may be a Christmas-themed character. The moisture sensor includes a PC board within the housing for determining water levels in the tree stand and uses a LED indicator and speaker to indicate when water levels are below a threshold.
