The GainSpan-Renesas Wi-Fi Sensor application works with Gainspan Wi-Fi Adapter board or Wi-Fi module mounted on the Renesas RDK ( RL78, RX62, RX63). The application displays the temperature, light and spatial orientation as sensed by the temperature, light and accelerometer sensors on the Renesas RDK and allows user to remotely turn on and off the LEDs mounted on the RDK, using an iPhone, iPad or iPod Touch. When the display mode is changed to landscape, it graphs the various parameters as they change with time.
