Precise wireless temperature sensor powers itself

January 20, 2015 // By Kris Lokere, Linear Technology
This case study shows a real-world design that combines a high-resolution temperature sensor, a power management circuit that uses solar energy when available and battery backup when needed, and a low-power radio module that automatically forms a reliable mesh network to wirelessly connect all sensors to a central access point.
