Hi All
I have a electrical type problem that I'm hoping someone (please) will be able to help me with.
Im creating an audio soundscape art installation that will use 3 'sound pods' to create audio soundscapes when they detect movement (via Passive Infra Red sensor). Each 'pod' runs from 3 1.5v AA rechargeable batteries.
Here is my problem, the installation is in a forest, and the exhibition goes for 3 months.
So I need a SOLAR charging solution for the pods. Each pod draws 30uA in standby and 130uA when triggered and playing a sound recording.
I have plenty of solar charges to choose form, only I also need some clever thinking around this. I need a solution that will enable me to keep my pods up and running for 3 months with no maintenance, which means I need the devices to charge and run at the same time.
This is what Im thinking...
As I cant charge and run at the same time I need a circuit to run the pods in standby (30uA) and charge the batteries. When the device is triggered I need POD to switch from Solar to battery, when the audio recording is finished to revert back to Solar charge for running the pod and for charging the battery. Unless anyone has another idea.
Some specs to the sound module Im using attached.
Does anyone now how to do this, could you help me? Im a OK with a soldering iron, no expert though, can follow circuit diagrams if forced to, I would rather buy a completed solution if any exist.
I would be grateful for any help / considerations
Regards
Tim
