Load cell, GSM module

Other Hardware Sensors

Dear All,

First of all I would like to thank you for reading my post.
I want to build a digital scale, using a load cell ( up to 100 kgr), height 1,2,3... times a day
and sent the results with a sms txt msg. The whole system to work on AAA batteries.
On top of that I want to be able to connect various sensors as well.
Do we have to use an amplifier or noise cleaner for the load cell (maybe 4 capacitors) ?
How long you think the batteries can last if you do one measurement per day and sent out only 1 sms on 2 AAA batteries?
My concern is, as being new to arduino, the power consumption, which parts to use, and if there
is an open source code for something similar.

Regards

we definitely have to use an amplifier for the load cell or connect it straight to analogue in?
mcp3551 will do the trick and work fine with arduino?

Thanks

Tried Google?

hx711 load cell (with or without "arduino")

arduino power consumption

arduino sleep

battery amp hours

etc etc etc

Dear Evans,

Yes I tried google thanks for your suggestion
