Tired of missing data from remote sites because your sensor dies or loses signal? The Dragino SN50v3-LB-EU868 Waterproof Long Range Wireless LoRa Sensor Node is built to survive harsh weather and send reliable readings over many kilometres. It solves the common problem of unreliable outdoor monitoring, giving you continuous information without frequent battery changes.
Dragino SN50v3-LB-EU868 Waterproof Long Range Wireless LoRa Sensor Node
Many farms, water utilities and smart city projects need a sensor that can stay online for years in rain, snow or dust. When a node fails, the whole data set becomes incomplete and decisions suffer. This Dragino node offers IP66 protection, a long-life 8500 mAh battery and LoRaWAN range that reaches dozens of kilometres, so you keep every data point alive. The node also includes a controllable 5 V output, allowing you to drive small pumps or alarms directly from the sensor. Its compact design fits into tight mounting spots, making installation quick and painless.
Key Features
