Personally, I think that a “real” SDR radio is one where the radio signal is received by the antenna and then (possibly after passing through passive filtering circuits) is sampled by an analog-to-digital converter. Further processing of the signal takes place in the digital domain. However, the SDR category also includes other devices which to […]

Software Defined Radio with Arduino Nano
Arduino is a favorite toy for electronics enthusiasts. There are thousands of designs around these modules. Here’s the next one – the simplest and cheapest SDR receiver in the world! A “real” SDR radio is one where the RF signal received by the antenna is directly sampled by an analog-to-digital converter. Further processing of the […]
Terminal for non-contact body temperature measurement
The non-contact body temperature measurement terminal detects people with a fever that may be the result of COVID-19 infection. It has a unique face recognition algorithm, so it can be used to register people suspected of sickness and can be used to verify the identity of people and grant people the right to enter the […]
