LOW-COST, SHORT-RANGE ANALOG SENSING MODULE
The SignalFire Remote Sensing System™ is a flexible adaptive radio networking system that seamlessly integrates analog and digital sensors. With a range of up to 5,000 meters, the system is self installing and self configuring. All the installer has to do is set the check-in frequency using a simple rotary switch, record the radio address, and connect the sensor. This system compares very favorably, from a cost perspective, with installed conduit at distances of 100 feet or more.
Features and Benefits of the A1 Sensing Module
The A1 integrates a SignalFire radio, sensor interface, high-capacity lithium batteries, and an antenna into a single, easy-to-install package.
Built for rugged outdoor use, the A1 provides a cost-effective solution to short runs of conduit in monitoring applications — even short runs can be cost prohibitive, especially if they have to cross a road or be buried. The cost of the A1 is less than the installed cost of 60’ of conduit.
The A1 enables robust communications with a SignalFire Gateway or other nodes in the SignalFire mesh network at ranges of up to 1/3 mile (500 meters). Data sent from the A1 to the Gateway is stored in its most recent values in a Modbus format.
Like the longer-range SRFSS-A2, the A1 connects to an industry-standard 4-20 mA or 1-5 V sensor, so you can use the sensor you want, not the one dictated by a vendor. And, like the A2, the A1 powers the sensor during the measurement cycle from its internal battery, making external power supplies unnecessary.
