Selkirk
Sensors and Monitoring
FREQUENTLY ASKED QUESTIONS
Selkirk's Remote Sensors are designed to be most accurate and economical when placed at approximately 200 meter intervals.
To ensure sensors are always connected, we use a combination of industry standard LoRaWan Networks, LTE, and satellite communications. This ensures two-way communication in all areas.
Selkirk Sensors are an invaluable technology for monitoring microclimate conditions specific to your area. This includes moisture content in the soil and air, temperature, and air quality. Our technology also has the capacity to monitor soil nutrients and minerals. When implemented, Selkirk Sensors can help increase yield, optimize irrigation, asses seasonal patterns and trends, and continuously monitor for risk assessment.
Our technology is designed for long-lasting durability. Supercapacitors work in tandem with solar panels to ensure a long and powerful charge, while our casing is designed in-house with commercial grade products to weatherproof all internal components. Every sensor is guaranteed to last 10 years, maintenance free.
Selkirk Sensors are designed to recognize volatile organic compounds, volatile sulphuric compounds, carbon monoxide, and other gases in the parts per billion range. This allows sensors to detect smoldering fires, before the flames have fully developed, whereas traditional methods of fire detecting, such as cameras (thermal or infrared), look-out towers, or satellites require the development of flames in order to detect a spreading fire.
.
Selkirk Sensors can be placed almost anywhere. Our housing design allows for attachment to trees, poles, fences, rock faces, and more.
Using AI technology our sensors can be trained to identify the specific 'smells' of an ecological region. This is done by sending environmental samples back to our headquarters. We then burn, analyze, and store regionally unique volatile organic compounds (VOC's) for later recognition in the event of a fire.
After a thorough consultation to determine your specific sensor configuration, our technicians will come to your location with all the necessary equipment and technology. We will then install the Gateway and Remote Sensors, as well as set up your Selkirk account. We provide onsite training to familiarize all customers with our technology.
Yes. We provide 24/7 monitoring to ensure critical alerts are never missed. If a detected fire is not responded to within three minutes, we will contact you or send emergency crews if necessary.
Our network is made up of two sensor types, the Gateway Terminal and the Remote Sensor. The Remote Sensors are numerous, continuously monitoring and sending environmental information to the Gateway Terminal. The Gateway collects this data and forwards it to the cloud. From there it is organized and sent to the devices of our clients in an accessible format to assess current conditions as well as long term patterns and trends.
Environmental sensing alongside AI technology allows for high-accuracy pressure, humidity and temperature readings. The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. See technical specs for our sensor below.

We recommend putting one Gateway Terminal for every 3km squared, which equates to 75 Remote Sensors.
The configuration of each Selkirk Network is dependent on multiple factors. This includes topography, existing infrastructure, and the area needed to be monitored--to name a few. However, we have identified two base configurations: area protection and point detection. Area protection is designed to monitor a large and unpredictable area. Point detection is designed to monitor a smaller or linear area where plausible fire activity is high, i.e., a railroad, hiking trail, logging road.
Forty point detection sensors placed every 200m on Vancouver Island’s popular Elk River hiking trail, spanning approximately 8km through two backcountry campsites.
CNRL in-situ thermal facility Jackfish 2 with 1km2 monitored in area protection configuration.
Risk assessment helps determine the plausibility of a fire. When environmental conditions reach a certain threshold, the user will be notified of an increased risk of fire. This done by using AI analytics to compile past forecasts and compounding risk factors including moisture in the air and soil, air quality, temperature, pressure, and wind.
