The SignalFire Remote Sensing System™ is a flexible, adaptive radio networking system that seamlessly integrates analog and digital sensors. A2 Long Range Node Series is self installing and self configuring. It also features up to a 3-mile range. 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.
It is sensor independent and simple to install and maintain. It offers a battery life up to 10 years, but depends on the type of sensor and reporting frequency. This series automatically configures as a star or mesh network and has a rugged design that works best in outdoor environments. It also includes an option for a solar power package.
