The INFWIN DigiTEMP is a rugged digital temperature sensor with SDI-12 or RS485/Modbus-RTU output, built for high-accuracy readings in water, soil, and air. Its fully-potted electronics and stainless steel housing suit harsh, submerged, or buried environments. Output interface, power supply, connector type, and cable length are configurable via ordering code - the default variant (DigiTEMP-BAB005) ships with RS485/Modbus-RTU output, 4.5–18V DC supply, a cold-pressed terminal connector, and a 5 m cable.

The probe is small enough to pass through standard 1" (2.5 cm) PVC conduit with 8" (20.3 cm) factory bend corners, and includes a loop hole for mounting weights or pulling the sensor through pipes or tight spaces. Reverse power protection and built-in TVS/ESD protection are included.

Key Features

High-precision temperature sensing: Accuracy as tight as ±0.2°C over 0–70°C
Digital output: SDI-12 (V1.3) for universal datalogger compatibility and low-power use, or RS485/Modbus-RTU for long cable runs or multi-sensor networks, both with built-in surge protection
Rugged construction: Fully potted electronics with no risk of leaking, inside a stainless steel body
Tough cable: UV-resistant polyurethane cable with waterblock construction
Conduit-friendly size: Fits standard 1" (2.5 cm) PVC conduit with 8" (20.3 cm) factory bend corners
Loop hole: For mounting weights or pulling the sensor through pipes or small spaces
Low power consumption: Suited to battery-operated dataloggers
Reverse power protection: Built-in TVS/ESD protection
Connector options: Cold-pressed terminal or stripped & tinned lead wires
Configuration utility: SensorOneSet software included for sensor configuration via RS485
ODM/OEM service available
Cable length: 5 m standard; custom lengths available

Applications

Soil temperature monitoring
Streams and surface water
Stilling wells
Dams
Aquaculture tanks
LoRaWAN IoT deployments via the Catena-5310 or compatible RS485/Modbus-RTU/SDI-12 gateway

Important Notes

The temperature sensing element is rated up to +125°C, but the long-term operating temperature for the sensor as a whole is −40°C to +80°C.
Accuracy varies by range: ±0.2°C (0–70°C), ±0.3°C (−40–80°C), or ±0.5°C (−40–125°C) - narrower ranges give tighter accuracy.
Suitable for immersed, surface, or buried installation.
When using Active Output mode on RS485, only one sensor should be on the network to avoid data collision.
