The OneGauge Hub is the “brain” of the OneGauge setup- it receives all of the sensor data and sends it to your selected screen. OneGauge is based on the popular Arduino platform, which makes it easy and very inexpensive to replace components in the future. Screw terminals are provided so that sensors can easily be added by the user.
A standard hub supports 3 analog temp sensors, 2 fuel level sensors, 1 analog pressure sensor, 5 digital pressure sensors (including vacuum/boost), 2 oxygen sensors, 3 voltage inputs, 2 RPM/tach or VSS speed inputs, 4 digital temperature inputs, 8 high temperature sensors, and various other optional features like a GPS speedometer, accelerometer for vehicle roll/tile or g-force readings, SD card data logging, a permanent storage device for Odometer/trip/hour readings, CAN-BUS communication with various devices like TPMS systems, 2 LCD screen outputs, and more. All of these can be custom configured when order to suit your needs.
