DataNab is offering a range of 1-wire temperature sensors that tie into existing GPS systems to provide temperature monitoring capabilities.
The sensors can connect to GPS devices and various other telematics systems to monitor temperatures in the engine, cab, or trailer. 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, DataNab, a supplier of sensors, automation components and streaming audio devices said.
“The ability to monitor and log temperature data has been available for some time, but usually only locally at the vehicles,” said Adam VanOort, president of DataNab. “Our 1-wire sensor solutions in conjunction with existing GPS hardware and telematics technology gives 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.”
According to the company, the design of 1-wire sensors allows multiple sensors to communicate over the same wire back to a single I/O pin on a device. This provides a more efficient alternative to traditional solutions that require a dedicated “home-run” cable and an independent input point for each sensor, and removes the need for multiple cable runs and A/D input connections on the 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, DataNab pointed out. Once connected, the devices can collect and report temperature data in real time.
