Challenge - RFID reader + Wifi Module Low Cost. Answered

Hi Guys,

I'm an Oracle Architect and I have one customer that want to monitor water dispenser, he wants to know if water bottle was changed. I have a software to control it, but actually the people need to input this data manually and I would like one solution to do it automatically. I'm thinking to use RFID Reader on water dispenser and paste passive tag on water bottle and with this I'll receive the information and this data must to be send using wifi, I can't have cable in this solution (data and power cable is not possible). In my investigation, I just find rfid reader (UHF) able read a passive tag in 1 meters distance, the issue is, the UHF module is very expensive, I saw UHF module for 40 USD and I need something more cheaper. Is there another way to do it? I need suggestions and help to developer it.

If need more info, send me email.

Regards, Haysar Lelis

I would use a simple doorbell ringer which you press when the bottle is changed good for 5yrs on the battery.

The bell which can be 10 meters away and is easily modified to trip a USB input for a momentary level change.

Boy you are stuck on the costly solution, RFID + WiFi over no alter the bottle just weight ..

A simple FlexiForce sensor and transistor equals pressing a button when the bottle weight is lifted to exchange the bottle :-)

Lots of other ways to automate..

If you go to Step 3, it will show the 2D water bottle sequential code

This is a water bottle.

Please note the 2D code sequence circled in red that may be sequential..

A one shot button, triggered when the bottle is inserted off-on, arranged so the removal doesn't trigger it. on-off.
