Offline RSSI based Object Detection in 802.11

Monitoring is one of the wide ranges of uses in Wireless sensor networks (WSN). The data that is retrieved from the sensor can be monitored with the help of the micro-controller unit. ESP8266, which gives an accurate signal measurement for the stations around us. RSSI or Received Signal Strength Indicator which can measure the signal power of receiver node which comes under Range based localization techniques. The micro-controller comes with IEEE 802.11 b/g/n standard that can measure the accurate RSSI values of the Wi-Fi devices, which can be displayed with the help of an asynwebserver, where the micro-controller acts as a Soft-Access point and the RSSI data that is collected can be monitored on the web page. Using an access point is an offline data monitoring method where users don't have an internet connection, but with the help of ESP8266, we can connect to the internet and, at the same time, users who are connected to local-host can also monitor the RSSI measurements through the Access Point. Using the help of a web-based cloud application from Google Sheets, the whole RSSI data is saved for further study or data analytics and live data is displayed in the sheets.
