Driveway Minder
The new Driveway Minder uses a commercial Driveway-Alert module which is wired to a buried sensor in the driveway. Note the counter to the right of the unit and the interface box underneath which connects to alerters in several areas. |

The old driveway minder used a modified surplus traffic signal "Left Turn Lane" sensor uses a buried loop under the driveway to sense a vehicle arriving. It also has a counter. |
Valhalla innovations had to include a way of signaling the arrival of guests. It started off with an old traffic signal "left turn lane" sensor. We had a lot of fun with it and missed it when it failed in 2004. Found a commercially available sensor and re-started the "barking dog" and "beeping whistle" signals. The counter was found in a box of old parts and it shows about 700-800 visits a year. What a surprise! |
