Additional Information about the SignalFire RANGER AirQ
Cloud-based Monitoring & Alarming
Data from the RANGER AirQ is transmitted to the SignalFire Cloud, allowing users to remotely view gas concentration trends, monitor site conditions, and configure alarms. Data can also be sent using MQTT/Sparkplug to a private cloud platform that supports the messaging standard.
This makes the RANGER AirQ a practical solution for organizations that need remote access to methane monitoring data without building a full communications network from scratch.
Methane Sensor Performance
The RANGER AirQ methane sensor is designed for fast, reliable field measurements. According to SignalFire, the methane version can detect methane concentrations from 50 PPM to 1,000,000 PPM and provides measurements in PPM along with environmental parameters including temperature, pressure, and humidity.
