I am thinking of changing the base to run on AC and the sensor on solar.
So questions
Its 4.5v for the base but will an output of 500ma be OK?
How can I adapt the sensor to run with solar? Would it be rechargeable batteries and
and solar and what specs if someone could help
Thanks

Re: WH1081 on AC
Hi,
The Console (base unit) runs from the USB power anyway and only requires about 50mA. If you don't run it from a PC 24/7 then you could use any mains powered USB adapter, but it would be better to stll put 3 x AA Alkaline cells in the Console as a (power fail) backup.
The best solution for the external unit is probably to use a pair of non-rechargeable Lithium AA cells, which should last for many years (even at very low temperatures).
But if you insist on using solar power, then the best technology is probably one AA (also known as 14500) 3.2 volt Lithium-Iron Phosphate (LiFePO4) cell plus one "dummy" (short-circuit) cell in the second position. These cells are often sold as "solar garden light" replacements, e.g. from Maplin. You would need a solar panel rated at about 6 volts, or it may be possible to "cannibalise" a solar garden light if you understand the principles of the electronics, which (despite their simple appearance) usually incorporate a low voltage PV panel and a voltage step-up converter.
Cheers, Alan.
