==Introduction to the product==


'''Description:'''

One of the implemented features for fleet management devices is a 1-Wire data protocol, which enables the connection of temperature sensors. It is a perfect accessory for temperature monitoring.

'''1-Wire temperature sensors is a great addition for your fleet management trackers in the following use cases:''' 

*Thermostatic controls – maintain temperature near a desired set point.
*Thermally sensitive system – receive alerts when temperature enters or leaves pre-defined value.
*Consumer products – be assured that the goods which you are delivering will maintain high quality.

==Installation==
To connect the 1-wire temperature sensor you have to make sure to connect 3 PINs of the sensor to the PINs of your device correctly. 

Up to 4 sensors can be connected to our devices simultaneously.

==Device configuration==
The device reads the sensor data automatically after the sensors are connected, however, the I/O elements are disabled by default to save data. To receive data to the server, make sure that the appropriate I/O elements(Dallas Temperature # / Dallas Temperature ID #) are enabled.[[File:Io_1wire_temp.png|border|frameless|682x682px]]

The first ID is the sensor that is connected first, which can be changed from the software side without disconnecting the sensors. It can be done by navigating to the 1-Wire section and assigning the IDs of the sensors in your desired order.
