I have some driveway monitors like this, but the sending unit eats 9 volt batteries like crazy. Is there a way to mod the motion sensor/sending unit to use a more economical power supply? A big 6 volt battery, a little solar panel for a rechargeable batt of some sort, whatever.... I foresee mounting the sensor in a larger box of some sort, housed somehow with a larger, longer lasting battery setup than the one 9-volt that it uses now. Actually, as bad as the expense is having to change it out so often. I'm handy enough to do the work, just not knowledgeable enough to figure out what needs to be done!
The receiver part of the monitor setup can be plugged into the house power, eliminating the need for batteries in the receiver/alarm.
I'd like to make several of these setups to be able to sprinkle around my residence.
Thanks for any ideas and assistance.....
