Radon – osynlig risk som kräver kontinuerlig mätning Radon är en radioaktiv gas som bildas naturligt ur radium i berggrunden och kan tränga in i byggnader via sprickor i grunden och otika genomföringar. I Sverige är radon den näst vanligaste orsaken till lungcancer efter rökning, med uppskattningsvis 500 dödsfall per år. Strandenälsoverket rekommenderar att radonhalten…
Solar-powered IoT – monitoring without grid power Many of the most valuable IoT monitoring locations – remote pump stations, bridge structures, agricultural fields, mines – have no grid power. Solar panels combined with lithium batteries make autonomous, year-round IoT deployments possible even in Nordic latitudes. Sizing a solar IoT system A typical LoRaWAN gateway consuming…
BLE asset tracking explained Bluetooth Low Energy (BLE) asset tracking uses small, battery-powered tags that broadcast a signal every few seconds. Fixed BLE gateways in the building detect the tag signal and report which zone the asset is in to Sensor-Online. Unlike GPS, BLE is designed for indoor environments where satellite signals do not penetrate.…
Context turns data into decisions A sensor alarm is a signal. A sensor alarm with a simultaneous camera snapshot is evidence. Sensor-Online combines IoT sensor data and IP camera feeds so that every alarm notification includes the visual context you need to act immediately – without logging into a separate system. What the integration enables…
Track what matters – without breaking the budget Asset tracking no longer requires expensive proprietary hardware or cellular subscriptions per device. LoRaWAN GPS trackers and Bluetooth tags bring affordable, scalable tracking to vehicles, equipment and high-value goods – all managed in Sensor-Online. GPS tracking with LoRaWAN LoRaWAN GPS trackers report position at configurable intervals from…
The Benefits of using LoRaWAN devices in Building automation The Internet of Things (IoT) is changing how we live and work, and one of the most exciting developments in IoT is using LoRaWAN technology for building automation. LoRaWAN is a wireless communication protocol that allows devices to communicate with each other over long distances, making…
Radon – a silent health risk that requires continuous monitoring Radon is the second leading cause of lung cancer after smoking, yet it is invisible and odourless. Spot measurements give a snapshot but miss seasonal and diurnal variations. Continuous LoRaWAN radon monitoring with Sensor-Online provides 24/7 data, trend alerts and the documentation needed for regulatory…
As the world continues to urbanize rapidly, smart cities are seeking innovative solutions to enhance their infrastructure and services. Smart city applications have emerged as a promising approach, utilizing sensors and communication technologies to optimize everything from traffic flow to waste management. However, one technology stands out among the rest: LoRaWAN devices. With their long-range…
Smarta fällor sparar tid och minskar kemikalieanvändning Traditionell råttbekämpning kräver manuella kontrollrundor var 3:e dag. Med IoT-anslutna fällsensorer vet du omedelbart när en fälla har utlösts – och kan skicka fältpersonalen exakt dit det behövs. Ingen onödig runda, inga tomhändade besök. Så fungerar det En IoT-sensor monteras på eller inuti fällan och registrerar utlösning via…
Know exactly how much is in your silos Manual silo checks are time-consuming and risky. IoT-based silo monitoring with LoRaWAN LiDAR sensors gives you real-time level and volume data from every silo on a single dashboard – no ladders, no guesswork. Technologies for silo monitoring LiDAR (Time of Flight) – laser pulse measures distance to…
