Well-established principles, appropriate protocols and ciphers, and the randomness inherent in the physics of thermal noise add up to fortify systems to ensure they are both secure and efficient. The ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

Advancements in low-power and reliable wireless communications, together with improvements in sensor and energy harvesting technologies is making it more practical and more efficient to use this type ...
