Sentrius RS1xx LoRa-Enabled Sensors

Recommended for New Design (RND)

Overview

New!

- RS1xx with Ext. RTD Temperature Probe Sensor

- RS1xx with Open/Closed sensor + Integrated Temp / Relative Humidity

Now available: Sensor variants supporting LoRaWAN regions AU915-928 and a growing number of countries in the AS923 region

The Sentrius™ RS1xx temperature and humidity sensors enable battery-powered, local and wide-area sensor applications using LoRaWAN and Bluetooth 4.2! The RS1xx are small, rugged, and easily configurable sensors making it easier than ever to monitor environmental data with your own network of sensors.

Whether it’s the integrated temperature and humidity sensor or the external temperature probe sensor with a wider temperature range, both are powerful yet power-conscious sensors. Configurable to transmit infrequently and last for years on the same set of two replaceable AA batteries. This means minimal maintenance, a network you can deploy and depend on.

Easily create a sensor network that provides miles of coverage, easily configurable via a Smartphone or tablet. Connect to any existing LoRaWAN network server or Gateway or, combine with our RG1xx Gateway to build your own end-to-end sensor network. Do it all with confidence, leveraging Laird Connectivity's decades of wireless design into the most reliable, customizable and high-performance sensor network available.

New sensors compliant with LoRa Alliance regional parameters and country radio certifications mean that, building on the existing popular North American (US902-928) and European (EU863-870) variants, Laird Connectivity now offer several new variants of the Sentrius RS1xx Sensors for operation in Australia (AU915 or AS923), Taiwan or New Zealand (AS923).

Note: Sensor operation cannot be switched between countries.

Note: The Sentrius sensor enclosures with external ports are not shipped with their associated sensor cable assembly (temperature probe, open/closed sensor), each part must be ordered individually. It’s a 1-2-1 ratio of sensor enclosure to cable assembly.

The Latest: Our New RS1xx with RTD Temperature Probe

Wide Range of External Temperature Monitoring Options

The RS1xx external RTD temperature probes serve specialized temperature ranges for accurate temperature reading in extreme environments.
NOTE: The RTD external temperature probe cable assembly is not included with the Sentrius sensor enclosure, or vice versa, each part must be ordered individually. It’s a 1:1 ratio of region-specific sensor enclosure to sensor cable assembly. For the full list of RTD supporting sensor enclosure part numbers, please refer to the product briefs (linked below) or the Part Number table below.

FAQ

Why I can't see any temperature value from my RS1xx?

It's important to note there are multiple RS1xx versions :

Those version and probes aren't interchangeable.

For instance, If you take an RS1xx External Temp Sensor, it won’t be equipped with humidity sensor.
In a same way, you won’t be able to use an RTD probe on an Ext Temp Sensor.

It's also good mentioning that all of External Temp and RTD Sensors will work correctly if and only if their temperature probes are connected and well tighten. You can refer to this guide for installation : User Guide - Sentrius RS1xx Ext. Temperature Sensors

Also, ensure that your RS1xx is loaded with the last firmware version. This can be uploaded using the Sentrius mobile application.

Last but not least, please make sure to check your RS1xx part number to confirm this is the version you think it is.

If non of the above work, please contact Laird Connectivity Support.

When should I replace the RS186/RS191 batteries?

When should I replace the Rs186/RS191 batteries?

RS186/RS191 battery discharge is roughly linear up until 20%, at which point the batteries will start to discharge faster. It is recomended to replace the batteries ASAP after reaching 20% depending on the sensors duty cycle.

If your application provides battery notifications/flags then when the capacity reaches 20% would be a good time to push that notification.

Is RS186/RS191 battery discharge linear?

While there is a direct correlation between the sensor reported battery capacity and battery voltage, the discharge curve is not completely linear.

Between 100% and 20% its essentially linear but below 20% the battery discharges faster.

Therefore a when the battery reports 50% capacity  it has more like 45% of its run time remaining.

Why are the LEDs of my RS1xx with external temperature probe constantly on and it does not join the LoRaWAN network?

With the 1-Wire Digital Thermometer Probe, a connection problem at power up is indicated by both LEDs on the front panel being
constantly on. This is a visual indicator to the user that there is a communication issue between the sensor and the probe.

Please check the connector/plug of the external temperature probe for proper connection as well as its cable for mechanical damage.

Does the RS186 have a calibration certificate?

The RS186 has a SiLabs SI7021 sensor  integrated which comes with the following certificate of calibration;
https://www.silabs.com/documents/public/miscellaneous/si70xx-calibration-certificate.pdf

Laird Connectivity does not provide any additional calibration certification.

Do you have any battery life examples for the RS186/RS191?

The Sentrius app, freely available on Android/iOS allows you to play with different scenarios in its battery life calculator/estimator without needing access to the hardware. Note that the range from the gateway in LoRaWAN impacts the datarate/spreading factor which in turn impacts the time on air for each packet which in turn impacts battery life. 
 

How fast can the RS186/RS191 detect a change of the door magnet open/close sensor?

The latency of the RS1xx Sentrius LoRa sensor with external magnet open/close sensor is limited by the following reasons:

1) The RS1xx uses two internal dwell times to detect a door open and close. These can be set in the Sentrius smartphone app to a minimum of 5 seconds (which is also the default setting). So any state change faster than 5 seconds will be suppressed and a change or the open/close sensor state won't be transmitted faster than 5 seconds.

2) Independent of the dwell time the RS186 (EU868 region) faces a minimum LoRa uplink interval due to regulatory 1% duty cycle limitations of the 868MHz frequency band. At the maximum data rate (SF7BW125) the airtime is roughly 60msec, which then adds a dead time of 99x60msec=5.94sec. So from this we get a minimum cycle time of roughly 6 seconds. At the minimum data rate (SF12BW125) the airtime is roughly 1480msec plus a dead time of 99x1480msec=2.4min giving a minimum cycle time of roughly 2.5min.

So the latency of a door open/close state detection plus transmission for the RS186 would be 6 seconds at best case (maximum LoRa data rate SF7BW125) and 2.5min at worst case (minimum LoRa data rate SF12BW125).

The latency of the RS191 is not limited by duty cycle restrictions and hence end up at 5 seconds latency purely due to dwell time.

Can AS923 and AU915 networks coexist in the same area?

Yes, as long as they are operating on different networks such that AS923 sensors talk to the AS923 gateway and vice versa for AU915 devices. 

Can the RS1xx AS923 (455-00063) work with an AU915 gateway which uses overlapping channels to AS923?

No, an RS1xx AS923 sensor will not work with an AU915 gateway because it cannot receive the downlink packets due to differing bandwidth and frequency plans used and therefore will drop off the network.

What is the temperature range for the RS1xx sensors

While the standard RS1xx (455-0001 for North America) can support down to -40°C and RS1xx external sensor (455-0070 for North America) can support down to -55 °C, typical AA batteries do not perform well at below -25 °C. Industrial grade of AA batteries may support lower temperature but they are significantly more expensive that off the shelf standard AA batteries.

How fast can a door open/closed event be detected/transmitted on the RS1xx sensor?

The state change is based on ‘latency’;

  1. The RS1xx uses two internal dwell times to detect a door open and close. These can be set to a minimum of 5 seconds (which is also the default setting). So anything faster than 5 seconds will be suppressed and a change or the door won't be transmitted faster than 5 seconds.
  2. Independent of the dwell time the RS186 faces a minimum LoRa uplink interval due to duty cycle limitation. At the maximum data rate (SF7BW125) the airtime is roughly 60msec, which then adds a dead time of 99x60msec=5.94sec. So from this we get a minimum cycle time of roughly 6 seconds, hence smaller dwell times than 5 seconds wouldn't make much sense. At the minimum data rate (SF12BW125) the airtime is roughly 1480msec plus a dead time of 99x1480msec=2.4min giving a minimum cycle time of roughly 2.5min.

So the latency of a door open/closed state detection plus transmission would be 6 seconds in a best case scenario (maximum LoRa data rate SF7BW125).

This applies to the RS186 EU version due to duty cycle limitations.

The RS191 will end up at approximately 5 seconds latency, purely due to dwell time.
