iButton and 1‑Wire sensors
Who is driving and how cold the cargo is, on a single cable
Each driver touches their iButton key when getting in, and you know who drives, how much and where. On the same cable you connect up to 8 temperature sensors to monitor the cargo. All with a single device.
One single cable
Driver
John Smith
Driving since 08:12 · 142 km
Cargo temperature
Front
+3.5 °C
Rear
+4.1 °C
Freezer
-18.2 °C
Key and temperature sensors on the same cable
Three simple parts
iButton key
One per driver. Stainless steel, no battery, lasts for years.
Temperature sensor
Stainless steel probe with cable. Up to 8 per device.
Key reader
Mounted on the dashboard. Two wires to the device, no power needed.
Who drives and how the cargo travels
Spider IoT and Smart IoT read the driver key and the temperature sensors over the same cable. You do not have to choose between monitoring drivers and monitoring cargo.
Driver identification
- Each driver has their own key: you know who drives each vehicle
- Up to 100 authorized drivers per device
- Ignition-on and ignition-off hours, and kilometers per driver
- Alert when someone starts with an unauthorized key
Cargo temperature
- Up to 8 temperature sensors on the same cable
- Recognized automatically when another trailer is hooked up
- Sensors are numbered from the device itself
- The driver key can go on the same cable
100 authorized drivers
Load your team's keys. If someone uses a key that is not on the list, you find out.
Per-driver log
Every time a driver identifies, it records how long they drove and how many kilometers.
Up to 8 sensors
Measure temperature at several points of the cargo box with a single cable.
Recognized automatically
Swap the trailer and the device puts each sensor in its place, with no reconfiguration.
How it works
Identification happens in the device itself, so it works even without cellular signal at that moment.
The driver touches the key
A quick touch when getting in is enough. No need to hold it.
The device recognizes it
If the key is authorized, that driver's log starts. If not, an alert is raised.
The work is recorded
Ignition-on and ignition-off time and kilometers driven by that driver.
Your platform shows it
The data reaches your tracking platform for per-driver reports and alerts.
What you can automate
- Alert when someone tries to start with an unauthorized key
- Sound a buzzer if the driver has not identified
- Prevent engine start if nobody identified, using a relay
- Apply different rules for each driver
These rules are set up in the device with the event engine. If you prefer drivers not to do anything, there is also the ID Band Bluetooth wristband.
Several sensors, no reconfiguring every time
Built for real refrigerated transport, where boxes and trailers rotate between tractors.
One sensor: plug it in
With a single sensor there is nothing to configure: the device detects it.
Several measuring points
Up to 8 probes on the same cable, each in its own place in the reports.
Rotating trailers
Each trailer carries its numbered sensors. When hooked up, the tractor recognizes them in under a minute.
No extra tools
Sensors are numbered from the device itself, with no external programmer.
Where it is used
Fleets with several drivers
Know who drove each vehicle on each leg and for how long, without paper logs.
Access control
Alert or drive an output when someone starts without an authorized key, with rules in the device itself.
Refrigerated transport
Cargo temperature and an identified driver with a single installation and a single cable.
Swappable trailers
Each trailer carries its numbered sensors and the tractor's device recognizes them when hooked up.
Simple installation
The key reader connects with two wires and needs no power. Temperature sensors go to the same point on the device.
Two wires to the device, no power
Key and sensors share the same cable
Swapping the wires damages nothing
Compatible devices
The iButton key and wired temperature sensors work on Spider IoT and Smart IoT.
