			==Configuration==
			Before configuring, ensure that the DS18B20 sensor(s) are connected to the '''Transight''' telematics device as per the sensor pinout.
			Improper wiring may lead to failed communication or sensor detection issues.

			<div style="color: red; font-weight: bold;">⚠️ Note: Up to 3 DS18B20 sensors can be connected to any Transight device that supports 1-Wire functionality.</div>

			== ✅ Step 1: Enable 1-Wire Sensor Interface ==

			== ⚠️ Mandatory Finalization Step ==

			Apply and save the sensor settings.

			'''Command:'''
			<pre>

			SET TSMR:2
			</pre>

			== ✅ Post-Configuration Validation Checklist ==

			Once configuration is completed, verify the data stream:

			* 🔄 Monitor incoming packets from the device.

			* 🌡️ Ensure temperature values are included in the payload.

			* 📈 Confirm periodic updates from each connected sensor.

			* ✅ Check the accuracy and consistency of readings.
