For our final year project we want to make a sensor node that can be used in underwater Wireless sensor networks (sensing parameters can be anything-temperature/pressure)
Since this is underwater the transmission(upto 10ft underwater and then around 10 ft above water till the laptop) will take place using an acoustic modem.(We are still trying to find suppliers from where we can buy an acoustic modem or else we have a paper and may try to make our own using that as a reference).
Underwater node will be having sensor, controller, acoustic modem all encased in watertight box
Surface buoy will have acoustic reciever and a ZigBee/WiFi transceiver.
There are two methods for transmission that we will be trying:
- Directly from the underwater node using acoustic modem to surface base station.
- From underwater to a surface node using acoustic and then convert to RF then use a ZigBee/WiFi module to transmit to base station (laptop).
(We are considering these two methods since we are unsure if the first method will directly work)
1)Can method 1 directly work or is a buoy necessary?
2)Can we use Arduino for this project?
3)How to interface all the components?
