Fiber optic temperature sensor ARF818 series

wall-mountDIN railstrap-on

Product overview
The TEMP is a ready-to-use connected temperature sensor that measures temperatures and transmits data over a wireless network. The device includes an ambient temperature probe and a remote contact temperature probe (2 m cable). It is designed for remote monitoring of internal and external temperatures in storage rooms, cold rooms or any location requiring a device resistant to varying environmental conditions.

Highlights of the IoT sensor

• Ambient and remote temperature probes
• Over 15 years of autonomy (depending on version and configuration)
• Data transmission modes: periodic and/or event-triggered
• Local and remote configuration (USB-C and network)
• Data logging for optimal autonomy (historization up to 24 samples per frame)
• Compatible with KARE device management
• Available versions:
• LoRaWAN: EU863-870 / US902-928 / AU915-928 / AS923-1
• Sigfox: RC1 / RC2 / RC4
• Other version: TEMP2S with two external probes

Primary functions

• Measure: periodic temperature measurements (ambient and remote probe)
• Track changes: logging of measured values for analysis and autonomy optimization
• Alert: trigger alarms when configurable high and/or low temperature thresholds are exceeded; configurable alarm repetition for persistent events

Features

• Periodic transmission of temperature data (with or without logging of measured values) and/or transmission when thresholds are exceeded
• Configurable redundancy with adjustable number of data repeats per frame
• Configurable alarm repetition for persistent events
• LoRaWAN Class C support (with external power supply)
• Configurable life/frame parameters
• Configuration methods: local via USB-C port; remote via the network (set periodicity, transmission modes, alarm thresholds)
• Alerts for product error, configuration error and low battery

Decoding & documentation
Device data decoding is supported by the manufacturer's codec tool. Datasheets and technical reference manuals are available for the different regional versions.
