This specialised range of sensors utilises the 1-Wire serial communication protocol to deliver cost-effective, digital telemetry directly to compatible Teracom controllers. Operating on a master-slave architecture, 1-Wire technology allows multiple digital sensors to share a single data line. It strikes an ideal balance between the basic on/off signalling of digital switches and the heavy-duty industrial infrastructure of Modbus systems.
The 1-Wire sensor line-up is optimised for simple, multi-point environmental monitoring across localised facilities:
By utilising a shared, low-voltage digital bus, Teracom 1-Wire sensors provide an efficient, plug-and-play approach to scaling up your environmental tracking.
For Teracom units utilising 1-Wire sensors, the network topography is highly sensitive to cable capacitance and signal reflections, requiring a strict linear daisy-chain topology rather than a star or branch layout. To maintain data integrity, Teracom recommends a maximum total bus length of 30 meters using standard UTP cabling, with any branches (stubs) off the main line kept to an absolute minimum (under 1 meter). Deviating from a single continuous line or exceeding this distance creates impedance mismatches, causing data frames to bounce back and corrupt communication, which results in intermittent sensor dropouts.
