Build a demo IoT rf meter using Arduino hardware modules and Blynk IOT Cloud. Reads temperature, humidity and RF signal data from sensors. Leverages IoT, Blynk Cloud, and serial monitor. Code is well ...
The RF signal is digitized by a high-speed ADC chip and fed to an FPGA processor. It performs DDC / DUC conversion (digital frequency shift down or up the spectrum) - by analogy with a direct ...
It’s not so far-fetched though, while bugs and hidden cameras in for example an Airbnb may not have flashing LEDs, they still emit RF and can be detected with a signal strength meter.
