RANGER is a battery- or solar-powered LTE-M transmitter that powers sensors and transmits their measurements over LTE-M cellular networks using the MQTT/Sparkplug messaging structure to bring data into a SignalFire cloud or an existing platform.
New modules add capabilities for interfacing with HART & SDI-12 communication standards. The unit can power 15 HART devices when equipped with the HART expansion module and eight devices using the SDI-12 expansion module (depending on the current draw of each device). Using this option, users can choose from a wider variety of sensors that best fit their application and reduce installation costs by using a multi-protocol sensor-to-cloud platform.
