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.

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 ...
