The high-level block diagram of the CS algorithm based on the squint equivalent range model is illustrated in Figure 1. The algorithm mainly includes operations of four FFTs, three phase functions, and two Doppler parameters (Doppler frequency center (DFC) and Doppler frequency rate (DFR)) ...
ATMega32 controls all the sensors to transmit the air-quality data to the web server using an ESP8266 module through WLAN and internet connection in an interval of 5 min. The processed air-quality data were visualized graphically on the web pages and an LCD. The sensor node works using an ...
The Electromyography diagram produced by the corresponding sensor represents the intensity of muscle contractions in a fairly clear way. It is more preferable to focus on the differences of the successive measurement values instead of the absolute ones in this graph. Furthermore, in order to avoid ...
