A
SECURE, SCALABLE WIRELESS SENSORS FOR LONG RANGE IOT APPLICATIONS
Laird Connectivity’s Sentrius RS1xx external RTD temperature probe is a
battery-powered, long range sensor platform that leverages the benefits of
LoRaWAN and Bluetooth Low Energy (LE) connectivity.
Packaged in a small, rugged form factor containing superior RF performance
and connected to a stainless-steel probe measuring just 50 millimeters
(1.96 inches) in length, housing a Class A tolerance PT100 RTD with
a measurement temperature range of -100°C to +100°C (-148°F to +212°F)
At the low end of the supported range the external temperature probe is
ideally designed for monitoring temperatures of shipped food products (ice
cream / frozen steaks) or for transportation of vaccines and transmitting
your data over LoRaWAN.
▪ Multi-wireless: LoRaWAN (868/915/923 MHz) and Bluetooth v4.2
(Central/Peripheral) with fully integrated high-performance antennas
▪ External Sensor Probe: Class A PT100 RTD temperature sensor contained
within a stainless-steel probe housing
▪ Fully certified for FCC/IC/CE/ASNZS/NCC/IMDA and Bluetooth SIG
▪ Simple wireless configuration using mobile application over BLE
▪ Harsh Environments: Robust IP65 enclosure to serve many varied
installation needs
▪ Integrated out of the box networks: Default configuration with Laird
Connectivity’s RG1xx gateway for simple, out-of-the-box cloud
connectivity
At its core, the RS1xx external RTD temperature sensor utilizes Laird
Connectivity’s field proven and reliable RS1xx Series hardware, providing
LoRaWAN options in 868, 915, and 923 MHz frequencies. The RS1xx works
with Laird Connectivity’s Sentrius RG1xx Gateway for simple out-of-the-box
integration and is compatible with third-party Cloud and LoRa network
ecosystem partners.
Develop a fully owned private LoRaWAN network to capture, route and
process IoT data for your application. Choose from RM1xx modules,
RS1xx finished sensors, or RG1xx Gateways
Robust enclosures provide a robust and resilient platform for recording
and delivering sensor data from a range of harsh environments

-100°C (-148°F) to +100°C (+212°F)
Variance of reported temperature data can be calculated taking the following uncertainties into account:
i) Where t = -100°C to -90°C,
Accuracy of measurement is ± (0.33°C + 0.047 |-90-t|)
OR
ii) Where t = >-90°C to +100°C
BS EN 60751:2008 / IEC 60751 standards for class A PT100 applies, which state accuracy of
measurements to be ± (0.15°C + 0.002 |t|) PLUS
iii) RTD-to-Digital conversion, utilizing the MAX31865 with a ‘Total Accuracy Over All Operating Conditions’
of 0.5°C
As such, max. variance at -100°C = +1.3°C or max. variance at +100°C = +0.85°C

Note: The RTD external temperature probe cable assembly is not included with the Sentrius sensor enclosure and each part must be
ordered individually. It’s a 1:1 ratio of region-specific sensor enclosure to sensor cable assembly.
Additionally, sensor cable assemblies available as part of the Sentrius product range are not interchangeable between Sentrius
sensor enclosures (blue housing) with RJ45 port. The user must connect the appropriate sensor cable assembly with the intended
enclosure. Please check the product description on the sensor label/part number on the packaging if in doubt.
