Phase detection system

Recently, during the project, there was a need to implement a system that was meant to signalize whether it is a phase or not. And that the system output signal is acceptable for the microcontroller. I have considered a few options that I’ll show below. It should be remembered that in the presented systems there […]

MQTT protocol

The MQTT communication protocol is based on the publication and subscription pattern. Its main advantage is lightness, so it can be implemented in very small microprocessor systems, and at low data transmission. MQTT was created by Andy Stanford-Clark and Mihaelaanca Nippera in 1999 year. The MQTT protocol is a special application in the IoT industry. […]

Small Metex Lab

Having the Metex multimeter at my disposal I decided to use its function to transmit the measured value via RS-232. The starting target was the display of measured values, recognition functions and units of the measured parameter. Ultimately, I developed a firm presentation of the data and in the end result in the program we have […]
