Arduino XBee Temperature Sensor

This project shows you how to build wireless temperature sensor with arduino and XBee. It uses LM 34 as temperature sensor. The project configured the radio at the sensor end to read the analog input of pin 19 every 4 seconds and to send a sensor reading packet. Both the sender and receiver radios should be running the API firmware. Input pin 19 on my sensor radio is configured (parameter D1) with value ‘2′ which means that it will read analog input, and the IO sampling rate (parameter IR) is set to ‘1000′ which sends a sample every 4096ms.
