Commercial Opportunity: Monitoring

Post by jonathan »

Problem: Real-world Monitoring

I would like someone to create an "environment" monitoring device. I know a customer who would like to purchase approximately 50 of these devices for a test run in a much bigger market. Anyone who is interested in designing and building this system should get in touch with me for more information.

This device is trained to recognise a particular physical input - assumed to be an analog waveform read from a sensor (it would be best to consider an audio input, but the design might be best left general) - and to record approximately timestamped instances of this input. It must be capable of reporting periodically (daily) on the number and pattern of inputs remotely - preferably via a mobile phone network. The device must be battery-operated and the aim is to last for at least a calendar year before a battery replacement is necessary.

The device should be easy to deploy: it should be placed it in the target environment and a button pressed to record the (audio) input to be detected (one or more times if necessary).

It doesn't have to use an XMOS chip, presumably.

No, not necessarily. I'm open to someone solving it with an XMOS chip or without.

By the way I didn't mention, you are not particularly space-constrained. The battery can be rather large if necessary.

In the specific market we're talking about, unit price of GBP40 = easy sale, GBP70 = tough sale, GBP100 = nearly impossible. Note that this will change over time. In 6 months, it's possible v2.0 can fetch GBP100 or so and still be purchased. But you need to prove business efficiency savings first!

Such a price seams pretty reachable, unless it needs to work in a tough environment (Like waterproof and such)

Really? Im interested in the battery technology you are thinking of in order to reach that price point given the specs?

I was thinking something like this might be suitable (although i am unsure of the price) the type XXI model could probably power a mobile device for about a year.

How about making it not need a huge battery. Use a low power MCU and use sleep mode as much as possible, so a couple of AAs should work fine. Its best to use a common battery instead of some internal lithium thing.

If I understand correctly this device has to do audio recognition (of an unspecified type) 24/7 for a year and occasionally fire up a mobile phone. Will even the lowest power MCU available do 8000+ hours of DSP on a couple of AAs? That's abour 5000mAh over 8000 hours - 0.625 mW? That's not much.
Best friends with the code fairy.

You should add a solar panel to recharge where possible?
