The PressureScout-LR uses LoRaWAN network to wirelessly send pressure measurements with a range of up to 10 miles (16km). The compact and industrial grade design is ideal to monitor pressure in harsh environments. The PressureScout-LR offers unique sampling methodology to report by exception while offering a great battery life of up to 10 years. It also allows remote applications to make changes remotely and to get device alarms.
Operating Temp: -40 to +176°F (-40°C to 80°C)
