Hi,

maybe open source software/hardware WiFI 2.4GHz module ?

It costs about 25$

Hi,

I would like to build an wattmeter with ACS714 and i need a low cost RF Transceiver that i can build inside each wattmeter so that it can transmit to another Transceiver it’s value. Since i need to build many of these then what is the cheapest one i can get ? I have following requirements :

  1. Must be lowcost

  2. Need a range that can cover a house (big)

  3. Low powered

  4. Multiple items must be able to exist close to each other without interfering.

  5. Be able to connect to Arduino

I intend to have everything going in a prototype then be able to put an microcontroller, transmitter and the ACS714 on the same PCB so i can make some cheap wattmeters for my home and my parents.

@gedass thank you but waaaaaay to expensive. The RF links i found are VERY cheap and looks to be reliable.

My PCBs have been posted, I should get them next week. I think I’ll design one using an AVR.
