Media for usb data collecting?

usb data collecting?

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,
