Autonomous sensors

Definition

Autonomous sensors are self-sufficient devices that can collect, process, and transmit data without needing continuous human intervention or external power sources. These sensors often utilize energy harvesting techniques to power themselves, making them ideal for remote monitoring and environmental sensing applications. By operating independently, they provide real-time data while minimizing maintenance needs and energy consumption.
