1-Wire Temperature Sensors

Introduction to the product

Description:

One of the implemented features for fleet management devices is 1-Wire data protocol, which enables 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 goods which you are delivering will maintain high quality.

Technical characteristics:

• Stainless Steel Tube
• 1-Wire Interface
• Unique 64-Bit Serial Code
• ±0.5°C Accuracy from -10°C to +85°C
• No External Components Required
• Stripped & Tinned Terminal
• Can be Powered from Data Line (parasitic connection)
• Power Supply Range: 3.0V to 5.5V
• Temperature Range: -55°C to 125°C (-67°F to +257°F)
• Waterproof
• 8 meters cable length

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.

PIN NUMBER	PIN NAME	DESCRIPTION
1	1-wire Data	Outputs temperature data via 1-Wire interface
2	1-wire Power	Power supply for the sensor (can be left disconnected in parasitic connection)
3	GND (-)	Ground.

Device configuration

The device reads the sensor data automatically after the sensors are connect, however the I/O elements are disabled by default to save data. To receive data to server, make sure that the appropriate I/O elements(Dallas Temperature # / Dallas Temperature ID #) are enabled.

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