+<p>The Sensor Service API uses objects to represent sensor channels. One
+object contains the information for one sensor channel (see the following
+table). The Sensor Service API methods use these sensor channel objects as
+follows:</p>
+<ul>
+<li><p><a href="GUID-46DB749E-A388-46B2-BB13-A274385CA97C.html#GUID-46DB749E-A388-46B2-BB13-A274385CA97C"><code>FindSensorChannel</code></a></p>
+
+<p>The <code>ReturnValue</code> property of the result object is
+an <span>iterator</span> containing
+the requested sensor channel information. Each item (object) in the <span>iterator</span> corresponds
+to one sensor channel matching the <a href="GUID-A4538B4D-0D90-43F8-B1FA-72F616937760.html#GUID-A4538B4D-0D90-43F8-B1FA-72F616937760">search
+criteria</a> specified for the <code>FindSensorChannel</code> call.</p>

+
+<p>The <code>criteria.ChannelInfoMap</code> property used
+for input is a sensor channel object. It specifies the channel from which
+the <code>RegisterForNotification</code> call registers to receive
+data.</p>
+
+</li>
+<li><p><a href="GUID-C2731B38-6294-419C-B7E2-AFB918F508D4.html#GUID-C2731B38-6294-419C-B7E2-AFB918F508D4"><code>GetChannelProperty</code></a></p>
+
+<p>The <code>criteria.ChannelInfoMap</code> property used
+for input is a sensor channel object. It specifies the channel of the property
+about which the <code>GetChannelProperty</code> call retrieves information.</p>
+

+<p>Each physical sensor registers to the S60 sensor framework as a Sensor
+Subsystem that provides specific sensor data. If the physical sensor provides

+one SSY for orientation data and another for rotation data. <code>ChannelType</code> thus
