Challenge - RFID reader + Wifi Module Low Cost. Answered
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.
