I'm new to building circuits, but have repaired and diagnosed minor problems with them for a while. Being new to building them I don't always know why or when or what is needed in the circuit.
Here is a project that i've been asked to figure out that I need some help with:
It's going to have 3 seperate parts that will need to send small amounts of data when they get close to each other. I was thinking of using bluetooth class2 for sending and receiving the data (would take suggestions here if FM or something else would work better). PartA will need to have a GPS chip in it to send the location through the bluetooth to PartB when it gets within 20ft of PartA. PartB will then send the location it received from PartA to PartC when it gets within 20ft of PartC. PartC will be hooked up to a scale and will store the location and a tag of some kind (simple number of which PartB it's getting the data from) and the weight from the scale while PartB is on it. At the end of the day it needs a way to pull all the data it has stored from that day (simple USB connection with a memory key plugged in the whole day, or some way to plug it into a computer to pull that information off it, maybe even a way to use the bluetooth to connect to another device and pull the data off, any other suggestions here would be helpfull as well)
So in summery I have:
PartA- Bluetooth with GPS possible proccessor if needed to send location
PartB- Bluetooth with small storage and possible proccessor to know when to recive location data and when to send location data
PartC- Bluetooth with some form of interface and or storage, something to trigger when to receive the data and an interface to plug into a scale to receive the weight.
I'm not sure on sources for all of the parts (like the GPS chip and antenna) I've found a lot that have resistors and boards and bluetooth and FM transmiters and recivers. But I wouldn't mind suggestions of places anyone else gets their parts from. I'm not 100% sure on if I want to have a company make the boards and have me put all the parts on it, or if I'm just going to make a PCB and put the parts on it.
Any help or suggestions would be greatly appreciated. So Thank you in advance.
