IoT Telemetry Sensors — Fuel Level, Cold Chain Temperature and CAN Bus Engine Data
SNTech's IoT telemetry range extends your visibility beyond the vehicle — into trailers, cold stores, fuel tanks, generators, and industrial equipment. All modules connect via 4G or NB-IoT and stream data to the same SNTech dashboard as your GPS trackers.
Which sensor adds the data you are missing?
A GPS tracker tells you where a vehicle or asset is. These modules add what is happening inside it, and stream it over 4G or NB-IoT to the same SNTech dashboard:
- FLV-01 — fuel level and theft. A non-invasive ultrasonic sensor that needs no tank drilling, works with any tank shape to ±0.5%, flags sudden drains as theft events, and calculates fuel consumption per km. Pairs with the R12L and R56L trackers.
- TMP-01 — cold chain temperature. Up to four probes per unit, −40 °C to +85 °C at ±0.2 °C, instant breach alerts, and HACCP/GDP logging with MOH- and SFDA-ready reports.
- TEL-CAN — engine data without extra sensors. Plugs into the J1939, OBD-II or K-Line bus to read up to 128 parameters — engine RPM, coolant temperature, fault codes, fuel rate, AdBlue level, engine hours and idling — on 5, 12 or 24 V vehicles. Plug-and-play with the R56L.
Engine and fuel data from these modules also feed predictive maintenance, and temperature data feeds cold chain monitoring.

Frequently Asked Questions
How does the fuel sensor detect theft?
The FLV-01 measures fuel level continuously and raises an alert on a sudden drop that does not match normal consumption. Because it is ultrasonic and non-invasive, the tank does not need to be drilled.
Which trackers do the sensors work with?
The FLV-01 fuel sensor pairs with the R12L and R56L trackers, and the TEL-CAN module is plug-and-play with the R56L. All modules report to the same SNTech dashboard as your GPS trackers.
What engine data can the CAN bus module read?
Up to 128 CAN parameters, including engine RPM, coolant temperature, DTC fault codes, fuel rate, AdBlue level, engine hours and idling time, over J1939, OBD-II or K-Line.
How accurate is the temperature sensor?
The TMP-01 measures from −40 °C to +85 °C with ±0.2 °C accuracy, and takes up to four probes per unit.
How do the sensors connect?
Over 4G or NB-IoT, streaming data to the SNTech dashboard alongside your tracking data.
