ONEGAUGE FEATURE LIST
This page lists all of the OneGauge features and explains how they are purchased and used. For specific screw terminal numbers and installation details, please visit the Sensor Links page, the OneGauge Sensor List, or the OneGauge Installation Instructions.
For a complete list of features, see the bottom of this page.
THE ONEGAUGE HUB
The OneGauge Hub is the “brain” of the OneGauge setup- it receives all of the sensor data and sends it to your selected screen. OneGuage 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.
This Hub allows you to install the OneGauge system not only in modern vehicles with OBDII capabilities, but also in older, pre-OBDII carbureted or EFI vehicles. We are excited about a product that is essentially universal- the generic sensors used with OneGauge can be installed on anything with an engine- car, truck, boat, ATV, etc.
Every OneGauge hub includes wireless bluetooth communication with an Android phone or tablet running the Torque Pro app. Torque provides the easiest way to set OneGauge up and read your sensors, but is limited to Android devices. To expand OneGauge’s capabilities, you can:
- Run Torque Pro on a second Android phone/tablet
- Add an OBD adapter to use other apps on Apple and Android devices. This adapter provides a female OBDII port, just like a modern OBDII equipped vehicle, so you can plug in a standard bluetooth OBD reader.
- Add one or two OneGauge LCD touch screens that display your data. These screens can be customized and allow the addition of buttons and relays for other electronics in the vehicle. For more on touch screen options, see below.
Each OneGauge is housed in a protective box that shields it from the environment. Three options are available for boxes:
- No box included- great if you plan on mounting in your own housing.
- Standard ABS plastic box- a standard black box, ideal for mounting in high-heat areas like under the hood. No holes are drilled for wiring so you can drill and adjust the box as needed.
- OneGauge box- a custom molded box built for OneGauge setups. Currently these are not made to withstand engine temperatures, so we only recommend mounting them inside the vehicle.
If you need special features like waterproofing, please reach out to us to discuss.
Torque Pro, an app available on Android phones and tablets, is the simplest and most cost-effective way to view your gauges. Check out the app here on Google play or read an in-depth review with a list of features here.
We have also recently added support for RealDash, a similar app that has even more options for creating and customizing custom dashboard layouts and add elements like indicator lights, toggle switches, etc.
Torque and RealDash not only include the ability to customize your gauge layout and design, but you can overlay your gauges on top of other apps (like maps or your camera), log the data output by your sensors for later analysis, measure 0-60 and 1/4 mile times, and much more.
There are a vast number of apps out there for Apple, Android, or PC devices that allow you to read and analyze sensor data. OneGauge can be programmed to work with any of these if you select the OBD output upgrade for your OneGauge hub. We have a short list of apps we recommend due to their ability to incorporate more sensors into their app, ensuring that all of your OneGauge sensors can be read by the app. These apps include:
Android: Torque Pro
Apple/iOS: OBD Fusion or Engine Link
Windows: OBD Dash
LCD touchscreens are the most versatile and customizable display option we offer.These screens have a more professional and permanent appearance and are ideal for instrument clusters or center consoles. LCD touchscreens offer options such as on-screen buttons to control vehicle accessories via relays or LED lighting options for your screen bezels so you can add lights for turn signals, gauges, or warning lights.
If you have some graphic design skills, you can design your own gauges and gauge layout to fit your vehicle. If not, don’t worry- you can adjust one of our pre-made screen designs or we have designers available who could help you design your ideal screen. To see some of our pre-made screen designs, visit our Themes page.
SENSORS AND INPUTS
If you have a modern vehicle equipped with OBDII capabilities (all U.S. vehicles after 1995 are equipped with OBDII), OneGauge can read your vehicle’s built in sensors and incorporate them into your list of sensors that are displayed on your screen.
Temperature Sensors are offered in three varieties- analog, digital, and high-temperature. Threaded and non-threaded sensors are available. A standard OneGauge hub supports up to 4 analog temperature sensors and 7 digital temperature sensors.
- Analog sensors are the same type used in pre-OBDII OEM applications by vehicle manufacturers to feed your instrument cluster. These sensors are dependable and typically last a long time, but sacrifice a little accuracy.
- Digital sensors are a modern upgrade that provide more accuracy than a standard analog sensor. Digital temperature sensors can last as long as analog sensors if cared for properly.
- High temperature sensors are used for reading temperatures above ~220 degrees Fahrenheit (100 Celsius). Typically used for exhaust temperatures, OneGauge works with any K-type thermocouple sensors. Up to 8 modules can be added to the standard OneGauge setup to read up to 8 high temp sensors.
Pressure sensors, like temperature sensors, are offered in analog and digital varieties. A standard OneGauge setup supports up to 2 analog pressure sensors, one manifold vacuum/boost sensor, and 6 digital pressure sensors.
OneGauge supports three main pressure sensor types:
- Manifold vacuum/boost sensor measures pressure or vacuum at the intake manifold. These sensors are great for all engines but essential if you’re running a turbo or supercharger.
- Fuel pressure sensors can be mounted in-line with the fuel line. The user can select a carbureted sensor configuration (less than 10 PSI) or EFI (less than 100 PSI)
- All other pressure applications, including oil pressure, can be measured by 100 or 200 PSI sensors.
Two fuel level sensors are included with all OneGauge purchases. In addition, fuel flow sensors are available monitor fuel usage in your vehicle and provide a rough estimate of how quickly your engine is using fuel as well as your gas mileage.
As a note, the fuel level sensors must be programmed to your specific fuel take sender specifications. This requires knowing the resistance values of the sender at empty and full. This information is often easily found by contacting the manufacturer of your fuel sender or doing a simple online search.
Voltage sensors are also provided free with every OneGauge purchase. A standard OneGauge automatically measures the voltage provided to the system by the battery and also offers two additional voltage inputs for voltages up to 25v.
OneGauge also supports two other primary sensor types. A tachometer input is included with every standard OneGauge, but different vehicles require different tachometer solutions. Please review our Tachometer Writeup to see what would work best for you.
Air/Fuel Ratio or Oxygen sensors are also supported by OneGauge setups. The user can choose to install up to two oxygen sensors on a standard OneGauge hub in place of two digital pressure sensors. OneGauge supports a variety of Oxygen Sensor controllers made by Innovate Motorsports, Spartan Lambda Conrollers, Daytona, AEM, and Ballenger.
ADDITIONAL MODULES AND FEATURES
OneGauge supports a GPS speedometer setup that provide not only your vehicle’s speed, but also its latitude, longitude, altitude, compass direction, and time. A GPS speedometer eliminates the need to run a speedometer cable from your transmission, transfer case, or differential. Many phones and tablets provide this information, so please verify that you need a GPS speedometer before purchase.
An odometer module is also available with the purchase of a GPS speedometer that stores vehicle miles driven and adds the option of having a trip meter.
A clinometer, or inclinometer, is an option available to off-road drivers who want to know the roll or pitch of their vehicle. Like the GPS speedometer, these modules install easily into the OneGauge hub and can be added at any time.
Data logging is a feature that is often requested for racing or high-performance applications. Data logging is a standard feature in most phone/tablet apps like Torque Pro, so this is often the easiest route for most users. However, for those using only LCD touchscreens, OneGauge offers a data logging option that saves data to an SD card for future analysis. This feature must be added at the time of initial purchase, however, and cannot easily be added by the user after purchase.
Other additional sensors:
Proximity sensors are available to measure vehicle distance from an object. These work well as parking or reverse sensors to avoid obstacles.
An RFID/NFC module is available to control access to your vehicle. This allows a keycard, keychain dongle, or your phone to be used as a key to unlock accessories, like your door locks. These modules are often used in keyless start systems as well.
