Tiny Low Cost Receiver

If this question were posed on a discussion forum populated by individuals interested in constructing improved explosive devices, this might get quite a bit of activity.

Would you tell us what you are doing?

Lol, I suppose it could seem like an odd request, it's for a low cost portable in house, paging system, think like the old numbers from butcher shops, but with 21 century tech lol, it's a prototype system for a friend that runs a shipping company, to keep track of inventory leaving one truck and getting placed on another, very small scale experiment, at least for now.

Fair enough.

Curious about the one hour battery life... do you see these things being recharged often, or are they seen as a 'one-shot' deal?

Try Zigbee

Ty, zigbee is on the list

Wireless calling bell will fit the bill.

Thank you, the bells are a great idea, but we were hoping to have them disposable

That application still sounds suspect to me.

Just today, I heard news on the BBC where a remotely detonated bomb went off in some sorry part of the world in spite of the government turning off the mobile phone network to thwart just such an event. A TV remote control improvisation was tabled as a possible alternative detonation telemetry method in lieu of the more traditional method of mobile phone administered misery.

I can't see how the use that the OP suggests could possibly be of any practical benefit. Surely a shipping company can afford some portable low power transceivers (eg UHF walky talky).

How is the "shipping company" currently performing whatever this signalling solution is supposed to improve?

More information on the exact way and the circumstances under which this improvisation's signalling will be invoked and how the received signal will be interpreted with a quantified description of the benefit it would provide over the "shipping company's" existing method may help quell some suspicion regarding the end use.

Its not suspect lol, and you to be honest with the very limited range i specified loo, id hate to be anywhere near it, the "shipping company" as you call it, it called "spee-d" its a local company that a friend of mine owns, he does inventory transfer for small local company's, up to about 150 miles, the job these tags are supposed to do are 1, like i said, small scale and a prototype deployment, basically one person goes to pick up the shipment or transfer inventory, tags the boxes and then when they get transferred to other trucks, he has a audible indicator that all of the said inventory is on board, very small company, and its kind of his pet project, i am not an engineer, only offered my assistance, i have a larger knowledge of electronics than he does, at the moment, he does not have a working inventory tracking system, and just had a very clear idea of what he wanted, and no, i have no desire to "improvise" any devises

That sounds like an RFI application.
