SATRAN: A Wifi-controlled satellite antenna tracking system
https://www.electronics-lab.com/satran-a-wifi-controlled-satellite-antenna-tracking-system/
An antenna tracking system adjusts the axis of an antenna to follow a moving signal source like a communication satellite. The working of an antenna tracking system is quite simple; the antenna is, first of all, commanded to move in any direction. Then, the level of the received signal is compared with the previous signal […]
IoT: Log Sensor Data to Google Sheets using NodeMCU
https://www.electronics-lab.com/iot-log-sensor-data-google-sheets-using-nodemcu/
Data is regarded as the major value proposition of IoT. The ability to receive real time data from different sources, store it and process it into actionable insights to transform and optimize processes either in real time or not is of immense value. This is one of the reasons why device cloud is one of […]
