Snow sensors and assemblies for use with same
Snow sensors, methods and mechanisms for snow sensor reading responses, assemblies for use with snow sensors, such as snow removal systems and assemblies, plus related components, as well as component combinations and related methods.
1. A snow sensor, comprising:
a housing having a base and a post extending upward from the base;
a receiver positioned on the base;
one or more emitters positioned on the post, above and spaced apart from the receiver and configured to emit radiation downward toward the receiver; and
a window positioned on and extending along the base, between the receiver and the one or more emitters, and configured to accept snow accumulation;
wherein snow accumulated on the window between the emitters and the receiver 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.
2. The snow sensor of claim 1 , wherein the window is integrated with the receiver.
3. The snow sensor of claim 1 , wherein the radiation is infrared radiation.
4. The snow sensor of claim 3 , wherein the infrared radiation is provided by the emitters and by ambient light.
5. The snow sensor of claim 1 , wherein the numerical value reported by the receiver is used to determine the operation of a snow removal system.
6. The snow sensor of claim 5 , wherein the receiver is positioned on an electronics board that includes electronics electrically connected to the receiver and in communication with a controller for controlling the operation of the snow removal system.
7. The snow sensor of claim 1 , further comprising:
a controller, in communication with the receiver, configured to control operation of a snow removal system; and
the housing further contains the controller.
8. The snow sensor of claim 7 , further comprising
a switch contained in the housing.
9. A snow removal system, comprising:
a snow melting component; and
a snow sensor including
a housing having a base and a post extending upward from the base,
a receiver positioned on the base,
one or more emitters positioned on the post, above and spaced apart from the receiver and configured to emit radiation downward toward the receiver, and
a window positioned on and extending along the base, between the receiver and the one or more emitters, and configured to accept snow accumulation,
wherein snow accumulated on the window between the emitters and the receiver 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; and
a controller configured to send a command to the snow melting component according to the numerical value reported by the receiver.
10. The system of claim 9 , wherein the radiation is infrared radiation.
11. The system of claim 9 , wherein the command to the snow melting component comprises a turn on command or a turn off command.
12. The system of claim 9 , wherein the window is integrated with the receiver.
13. The system of claim 9 , wherein the controller comprises operational settings to control the snow melting component by way of a manual activation mode or by way of an automatic activation mode.
14. The system of claim 13 , wherein the numerical value that corresponds to the radiation received by the receiver is reported to a user of the system.
15. The system of claim 13 , wherein the controller includes a sensitivity setting when the controller is set to the automatic activation mode.
16. The system of claim 15 , wherein
the controller is configured to automatically activate the snow melting component when the numerical value reported by the receiver reaches a first setting; and
the controller is configured to automatically turn off the snow melting component when, after passing the first setting, the numerical value reported by the receiver exceeds the first setting.
17. The system of claim 15 , wherein the controller is configured to automatically activate the snow melting component when the numerical value reported by the receiver reaches a first setting.
18. The system of claim 17 , wherein the controller is configured to automatically turn off the snow melting component when the numerical value reported by the receiver reaches a second setting.
