Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals. In this design idea, you will ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

We’ve seen no shortage of projects that use the ESP8266 or ESP32 to add “smart” features to existing home appliances, often by pairing the microcontroller with a radio or IR transmitter. If your ...

Atmel’s ATA8520D is a transceiver IC for 868MHz Sigfox proprietary networks, intended to be used for IoT and machine-to-machine comms with the Sigfox protocol. It has an RF front end for up and ...

LOUISVILLE, Colo., May 30, 2019 – Inovonics, an industry leader in high-performance wireless sensor networks for life safety applications, announces the release of its new EH4104R single zone fire RF ...

How are we going to transmit our signal? Feeling ambitious, we decided to go wireless. We may not to able to make a mobile phone system but our very own radio station with a transmitter and receiver ...

AtmelCorporation (www.atmel.com) has combined an 8-bit AVR flash microcontroller with an RF transmitter in two new devices that target tire pressure monitoring systems. Atmel Corporation has combined ...
