Connect remote sensors directly to the cloud
The SignalFire RANGER Node is a battery-powered cellular transmitter for remote industrial and environmental monitoring. It connects field sensors to the SignalFire Cloud or another MQTT/Sparkplug-compatible platform without trenching, conduit or long communication cable runs.
The standard RANGER supports analog, digital and pulse signals with a controllable relay output. Optional modules add HART, Modbus RTU, SDI-12, RTD or additional analog and digital inputs.
