Part one starts with an explanation of the Arduino and Nanode platform, and takes us through connecting the Nanode to a wireless temperature sensor.

A temperature sensor, microcontroller, wireless module, battery, case, and miscellaneous parts meant each node in the sensor grid would cost about $10.

As such, I'd like to build myself some wireless moisture sensors for moderate scale production (consider 50 test points reasonable).

Moreover, the wireless temperature control device will send and receive electrical signals from the temperature sensor without the use of wires. In this device, Wi-Fi is used to transmit and receive ...

A Swedish software engineer makes a wireless Arduino clone called AADuino. The system fits neatly within the form factor of an AA battery.
