Want to add sensors to your setup? Here’s a full list of everything that works with a OneGauge setup.
Screw Terminals A1 – A6:
These six terminals provide six inputs for analog style sensors. The three sensors types used here are analog temperature, pressure, and fuel level sensors. The default Hub setup is listed below, but we have other sensors already programmed in that can be optionally added at the time of purchase or with a quick reprogram. If you need support for a sensor not on this list, reach out to us at info@TheOneGauge.com.
A1: Coolant Temperature – 3/8″ NPT Standard Motor Products TS58 or equivalent
A2*: Oil Temperature or Additional Pressure- 3/8″ SMP TS58 or 1/4″ Standard Motor Products TS58 or equivalent
A3: Transmission Temperature – 1/8″ Autometer 2259
A4*: Additional Analog Temp – 1/8″ Autometer 2259 or additional Fuel level
A5: Fuel Level (requires programming for resistance levels of fuel tank sender)
A6: Oil Pressure – 1/4″ NPT SMP TS58
*Terminals with an asterisk can be switched from the first sensor to the second using a switch mounted on the circuit board.
Screw Terminals B1-B7:
These 7 terminals are used for digital pressure sensors or oxygen sensors. All pressure sensors are universal 5v Pressure transducers that use a linear signal from 0.5v to 4.5v. These sensors are widely available on Ebay, Amazon, and other sites.
B1: Vacuum/Boost – MAP (manifold vacuum/boost) sensor; GM-style 3 bar MAP sensor.
B2*: Fuel Pressure – 100 PSI digital pressure sensor (for EFI) or 30 PSI digital pressure sensor (for carbureted applications)
B3: Oil Pressure – 150 PSI GM style Oil Pressure Sensor D1846A
B4*: 100 PSI Digital Pressure Sensor or Oxygen Sensor (see below for more info)
B5: 100 PSI Digital Pressure Sensor
B6: 200 PSI Digital Pressure Sensor
B7*: 200 PSI Digital Pressure Sensor or Oxygen Sensor (see below for more info)
Screw Terminals C1-C2:
Both of these terminals provide 0-25 voltage readings. Battery voltage is automatically provided when the OneGauge Hub is connected to a power source through the + and – terminals on the board.
Screw Terminals D1-D7:
These 7 terminals are all programmed to use DS18B20 digital temperature sensors. These popular sensors are widely available on Amazon, Ebay, or other retailers. The come in unthreaded and threaded varieties.
Screw Terminal E1:
Liquid flow input or other hall-effect based sensor input. Used for special applications; please contact OneGauge for questions on how to use a liquid flow or other hall-effect sensor.
Screw Terminal F1:
Tachometer signal input. Low voltage signals (12-15v) can be connected directly to this terminal (includes many MSD setups with direct tach wire, GM LS engines, and HEI distributors). High voltage applications require the Universal Tachometer Interface linked here, which also allows you to change the pulse frequency of the signal to fit your engine. Diesel setups may require an alternator tachometer setup; we use Autometer #9112.
The user is responsible for testing his/her tachometer signal voltage BEFORE using this screw terminal. The user is responsible for any damage to the OneGauge hub from excessive voltage.
