带太阳能电池寿命扩展器的高精度无线温度传感器DC2126A

The DC2126A is a high-accuracy wireless temperaturesensor that can be powered from ambient light. It is builtusing various integrated circuits from Linear Technology.A 24-bit delta-sigma ADC reads a thermistor biased froma precision voltage reference. A SmartMesh IPWirelessradio module provides the wireless mesh connectivity andcommunicates the temperature to a central access point(manager). A switching power supply harvests energyfrom the built-in solar panel, and automatically switchesover to the internal battery when no ambient light is available.
