Please log in for more thread options Anyone have recommendations for usb connected data collection devices, to be used within windows? I'd like to leave an old laptop on the boat this winter and have it send me information on air temp and whether the bilge pumps have been operating. Ideally I'd like something non-intrusive to monitor the bilge pumps, like an induction loop detecting when power is actually being used. I'd want to monitor two sets of 12vdc levels, three bilge pumps, two air temp values (cabin and engine compartment) and perhaps an IR motion sensor or two. Thanks, -Bill Kearney | |||||||||||||||||||

> think that's too much of a problem. Yeah, not to much trouble. I've got AC to the boat during the winter. I could step down the onboard 12vdc. But then again I may want to use something like X-10 (gasp!) to control power to it. I'm toying with using an old laptop to act as a 'watchman' on the boat. Just make sure it's not taking on water and know when the temps are getting near (and below) freezing. Then being able to have it send me the data or alerts should conditions merit. I'm having it handle informing me by using on-shore wifi, not a phone line or service on the boat itself. If I was keeping internet or phone service live on it all winter I'd probably go with one of the embedded devices like the Elk. If the AC power is out I'll know already via the laptop going onto battery mode. So the sensors being offline due to loss of AC would be obvious. The boat's about an hour away and there's staff on sight (and friends nearby). So losing data collection during a power outage isn't critical since I'm already going to be concerned about the loss of AC. Thanks, -Bill Kearney | |||||||||||||||||||
