The Data AcQuisition (DAQ) is to measure an electrical or physical phenomenon such as voltage, current, temperature, pressure, or sound which requires some form of monitoring or controlling. A small scale embedded system is designed for Wireless Data Acquisition (WDA) at 433MHz ISM band and the system is controlled using PIC Microcontroller. The wireless RF communication eliminates the need for devices to be physically connected for communication. The received data from sensor nodes are displayed in a personal computer PC.
