Analog and Digital Data Logger for Home Appliances

Imandu Hari Krishna, Bollamreddi Vvs Narayana


This paper proposed a portable wireless data acquisition system for temperature & voltage in real time process dynamics. Process variables (like temperature, pressure, flow, level, voltage) vary with time in certain applications and this variation should be recorded so that a control action can take place at a defined set point. This paper proposes an Arduino embedded platform for a sensor having a network interface using the Wi-Fiprotocol, which is specially designed for the sensors network. The Wi-Fi protocol is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power, wireless sensors network. This wireless data logger senses and monitors the variations in the local temperature thereby transmits the data within the range to an assigned embedded processor based server. Received temperature, voltage  is displayed on simultaneously on a telnet app.
