Wireless rodent trap sensor

Abstract

A single motion sensing assembly device will activate and transmit a signal when a rodent trap is triggered. The single sensor assembly provide a sensing rod attached to one side of a leaf of an open hinge and a magnet affixed to the same leaf on the opposite side. The magnet is positioned adjacent to a reed switch and transmitter which is attached to the opposite leaf of the open hinge. The sensing rod is moved up and down causing the reed switch to activate the transmitter.

Claims

1. A sensor system for monitoring a Rodent Trap, said sensor system comprising: a hinge upon which a sensing rod is attached to a first leaf positioned above a magnet attached to an opposite side of said first leaf; a battery, a reed switch, a microprocessor, and a wireless transmitter, all contained within a sensor housing attached to a second leaf of said hinge adjacent to said magnet; and a base weight upon which rest said magnet and said housing.

2. The sensor as in claim 1, wherein one end of said sensing rod is attached to said first leaf of said hinge.

3. The sensor as in claim 2, wherein said end of said sensing rod is attached to the center of said first leaf perpendicular to a pin of said hinge.

4. The sensor as in claim 3, wherein the opposite end of said sensing rod extends inches over the edge of said first leaf.

5. The sensor as in claim 1, wherein said magnet is attached to said first leaf facing the pin of said hinge.

6. The sensor as in claim 1, wherein said housing is attached to said second leaf of said hinge with said reed switch facing the pin of said hinge.

7. The sensor as in claim 1, wherein said housing is attached to said base weight.

DETAILED DESCRIPTION OF INVENTION

(7) Referring to the Figures, wherein like numerals indicate like or corresponding parts throughout the several views, an exemplary rodent trap is shown as 8 for purposes of illustration and not to be in any way limiting. The rodent trap 8 used in FIG. 1, is but one example of a variety of rodent traps which can be used for purposes of illustration.

(8) The subject invention will now be described with reference to the attached figures. FIG. 1 shows a perspective view of the subject device. The device is attached to a weighted base 6 which helps it maintain stability during engagement of the rodent trap. The device is positioned in front of a set non-engaged rodent trap 8 such that the sensing rod 3 hangs over the bail 9. Bail 9 is held in place by catch 10 which is releasable and held in place by bait tether 16. When the bait 15 is taken, bait tether 16 is altered releasing catch 10. When catch 10 is released, bail 9 moves in the direction indicated by the arrow A until it reaches the engaged position shown by the phantom in FIG. 1. The upward movement of bail 9 throws the mechanical sensing rod 3 upward. Although the sensing rod 3 is shown as an attachment to hinge leaf 1, it may also be made as a part of the hinge leaf 1 for durability. Hinge pin 7 connect leaf 1 to leaf 2 allowing leaf 1 to move independently. FIG. 4B shows the movement of sensing rod 3 causes magnet 5 to move away from sensor housing 4 where arrow A indicates engagement of the bail. FIG. 4A shows the device in the monitoring state, wherein reed switch 11 is sustained in the open position by magnet 5 being adjacent to it. When bail 9 is engaged, sensing rod 3 moves magnet 5 away from sensor housing 4 as demonstrated in FIG. 4B causing reed switch 11 to close which notifies microprocessor 13 powered by battery 14 to initiate wireless transmitter 12. The force of bail 9 engagement automatically reset sensing rod 3.
