Sketches for an Esp8266-01 STC 15f104W powered 1-channel relay board to be controlled remotely using an MQTT broker as communication bus without modifying physically the device nor using any third ...
Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...
Part of any self-respecting Smart Home, smart relays are useful for switching and monitoring loads that do not plug into an outlet. This also makes them a lot more integrated, and thus, a long ...
This is a library for the laser particle sensor module PM2005 manufactured by Wuhan Cubic Optoelectronics. The PM2005 module counts airborne particles of different sizes in catagories of 0.3, 2.5, and ...
Some kind of continuity beeper has been a standard piece of gear since the dawn of electronics. Sure, you probably have an ohm meter, but sometimes you don’t care about the actual resistance. You just ...
Abstract: This letter investigates the resource optimization problem for the multi-user multi-relay decode-forward (DF) cognitive radio networks. The novel optimization metric, namely the ...
Abstract: Resonant tunneling diodes (RTDs) have been widely adopted to implement communication systems in the terahertz (THz) range. This study presents a package of the RTD for a THz receiver at the ...
