Chapter 2 Introduction to the Sentinel
Introduction
The Sentinel Wi-Fi Sensors are devices with various sensors (depending on
configuration temperature, humidity, moisture, light) that use your existing
802.11b/g Wi-Fi network infrastructure.
The sensors will take a measurement at a regular time interval (for the remaining of
this guide, we will use temperature as an example) and report them to a local PC.
When not taking a measurement, the sensor will enter a low power sleep mode to
preserve the internal lithium battery.

and perform scheduled temperature measurements.
