Abstract: This paper presents the design, implementation and testing of a novel IoT monitoring and management system for household energy consumption, which leverages unique integration features with ...

You don’t see them much anymore, but there was a time when any hobbyist who dealt with RF probably had a grid dip meter. The ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

Bluetooth is everywhere, but it’s hard to inspect. Most of the magic is done inside a Bluetooth controller chip, accessed only through a controller-specific Host-Controller Interface (HCI) protocol, ...

Abstract: The design is based on Atmel51 microcontroller development platform and automatic control based on the principle of a digital voltage meter system. The system uses Atmel89C52 microcontroller ...
