The plan is to also do some interpretation of the data, e.g. graphing, and serve up that interpreted data within an HTML page.
I'd also like to be able to store the data for quite some time without having to archive it to say a PC.
I'm wondering if I'd be able to use an SD card for both storing HTML pages (for inserting data into) and also for storing the data.
Jluciani > I was thinking about using an XBee but they seem quite pricey compared to say an FM TX/RX pair. I think that Wattson Energeno design and manufacture products and services to assist people to maximise the efficiency of their energy usage and energy generation both online uses FM to transmit from the sensor to the display unit. Would that mean that only a single sensor could be used...?
