I currently have a Uno with an ethernet shield. I’d looking to use a remote sensor like this http://www.elecrow.com/devduino-sensor-node-v2-atmega-328-p-1046.html to report back to the Uno. Essentially I’d have the sensor send a report every hour, but I’d like the Uno to be able to also “request” and update for the current sensor values.
- What module would be recommended for the RF component?
- What sort of RF distance can be expected if just using a small extension wire as the antenna? (Need at Maximum approx 10 meters / 32ft)
- Can the values from the sensors be transmitted to the Uno, if using Analogue inputs
- I’d like to run some sought of framework on the Uno which would act as a server to collate/display the realtime sensor readings via a webpage (ajax/html5 ?). Also be able to have another PC query the Uno for its values, via jSON? Would be be recommended?
Thanks in advance!
