A range of 1-Wire temperature sensors integrates with GPS and telematics systems to add temperature monitoring functionality to existing vehicle tracking and diagnostics capabilities. The sensor technology provides GPS and telematics systems with the added benefit of monitoring engine, cab, trailer, or other temperatures, and delivers that information with the rest of the data in real time over the network — increasing safety, reliability, and quality control. The stainless steel sensors are especially useful in these situations as they can withstand the dirt, shock, and moisture associated with being transported. The 1-Wire sensor solutions, in conjunction with existing GPS hardware and telematics technology, give fleet managers and companies an inexpensive option to access this pertinent information in real time, enabling a quick and intelligent response to critical temperature-related maintenance, performance, and quality control data. The temperature sensors are used globally and are used in HVAC and refrigeration, as well as solar, geothermal, and other alternative energy systems to monitor and track system performance. The intelligent sensors feature built-in, uniquely addressed chips that enable multiple daisy-chained sensors to communicate back to a master over a single cable — ultimately reducing costs and installation time. The design of the sensors allows multiple sensors to communicate over the same wire back to a single I/O pin on a device. Devices that currently do not support 1-Wire can usually add that functionality through a firmware update if the device has a programmable I/O pin available.
