Waking up your IOT device when needed.
Chips for IOT Battery Life

University of California, San Diego (UCSD) researchers have developed a power-saving chip that could significantly reduce or eliminate the need to replace batteries in Internet of Things (IoT) device and wearables. The new chip wakes a device only when it needs to communicate and perform its function, allowing it to stay dormant the rest of the time and reduce power use. The wake-up receiver is an ultra-low power chip that continuously looks for a specific radio signal, known as a wake-up signature, that tells it when to wake up the main device. Said UCSD’s Patrick Mercier, “By adding a wake-up receiver, we could improve the battery life of small IoT devices from months to years.”... "
