WI-FI Based Wireless Datalogger
Vikram Kamadal | Manjula N Harihar 
Abstract: This paper aim is to develop a Wi-Fi based wireless Datalogger through which we can measure any physical or environmental parameters like temperature, pressure, current, water level, soil moisture, rainfall, wind speed and direction, pulse signals etc, and store the data for a period of time. Data loggers can record a wide variety of energy and environmental measurements including temperature, relative humidity, AC/DC current and voltage, differential pressure, light intensity, water level, soil moisture, rainfall, wind speed and direction, pulse signals etc. During configuration the datalogger is physically connected to the PC and search for an existing wireless network so that it can be placed anywhere within range of the network. Our developed system measures different physical parameters and retain them for a period of time using datalogger shield which is connected to PC through wireless with the aid of Wi-Fi shield. The Wi-Fi shield used here is Tinysine Wi-Fi shield and its based on roving networks RN-XV module. It provides the bridge between TTL serial port and IEEE802.11b wireless communication network, which helps to connect the entire setup wirelessly to the PC. This system is portable and easy to handle for recording all the physical or environmental parameters and storing it for a period of time.
