Temperature Sensors

Engine Temperature

Mfg Pic Pigtail Part Numbers Mechanical Analog Configuration Notes
GM SU109 C.jpg 5615pt.png
  • Wells SU109 : Standard Motors Products (SMP) TX3
  • Pigtail Pico 5615pt
3/8" NPT threaded brass body and a 2 pin terminal. <link to Race Capture analog channel configuration> Can be used for air inlet temperature for normally aspirated engines
GM SU107 C.jpg 5616pt.png
  • Wells SU107 : Standard Motors Products (SMP) AX1
  • Pigtail Pico 5616pt
3/8" NPT threaded brass body and a 2 pin terminal. <link to Race Capture analog channel configuration> Use for measuring air inlet temperature. Exposed sensing element, necessary for boosted engines where fast response times are necessary. Due to the fragility of the sensing bulb, it is necessary to pot the base of the sensor leads with sensor-safe silicone when used in high vibration environments.

Pulse Sensors

RPM

Wheel Speed

Pressure Sensors

Fluid Pressure

Brake pressure sensors will be used to capture inline brake fluid pressure. Combining this input with brake pedal travel can provide a way to show brake fade in real time.

Boost / Vacuum

Distance Sensors

Suspension Travel

Mfg Description Pic Pigtail Part Numbers Mechanical Analog Configuration Notes
DIY Sharp GP2D12 optical distance sensor Sensor GP2D12.jpg 3-pin connector GP2D12 custom <link> Optical distance sensor measures from 10 to 80 cm and outputs a voltage corresponding to that distance. To measure suspension travel, install a unit at each corner of car, targeting the road surface. May also be used for pedal travel as well, providing there is a target to sense

Angle Sensors

Steering Angle

Mfg Description Pic Pigtail Part Numbers Mechanical Analog Configuration Notes
DIY Sharp GP2D12 optical distance sensor Sensor GP2D12.jpg 3-pin connector GP2D12 custom <link> Optical distance sensor measures from 10 to 80 cm and outputs a voltage corresponding to that distance. To measure suspension travel, install a unit at each corner of car, targeting the road surface. May also be used for pedal travel as well, providing there is a target to sense. Create a target latched to the steering rod and use the travel out and back of the steering rack rod to denote the travel left and right for steering. This measures true steering(and ignores the speed sensitivity of steering systems, showing actual tire angle result, not steering wheel rotation). It also provides a quick way to verify alignment issues as location vs. gps/accelerometer travel in the "Straight ahead" direction will be at varying angles when alignment issues are present.

Throttle Position

Brake Position/Pressure

Linear Sensors

Wiring

Sensor Breakout Board

We've created an optional sensor breakout / distribution board that will make it easier to use sensors that require pullup resistors as well as making available multiple ground and 5V Vref connections. The built-in pullup resistors are easily disabled by breaking a designated trace on the board. This board is compact; enough to be bundled inline with your wiring harness. SensorX board.png
