The CarDr.com Bluetooth OBD Adapter (On Board Diagnostics ) connects to the scan port of cars - works with IOS, Android and PC's

OBD adapters are a valuable tool to received data from the CAN bus of a Vehicle. On-board diagnostics (OBD) refers to vehicle’s self-diagnostic and reporting capability. Modern vehicles provide real-time OBD data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow us to rapidly identify and remedy malfunctions within the vehicle. Onboard Diagnostic (OBD) is a manufacturing standard for cars made since 1996. Mechanics needed a way to retrieve information from the car’s internal components without splitting open casings, motors, or pulling out parts. Born of a need for efficiency, OBD and many related sensors can tell you everything you could want to know about how well a car works.

The OBD Parameters are : Engine load, Engine RPM, Vehicle speed, Throttle position, Coolant temperature, Fuel trim, Fuel pressure, Fuel system status, Intake manifold pressure, Intake air temperature, MAF air flow rate, Air status, Oxygen sensor status, Runtime since engine start, Distance with MIL on, Fuel tank level input, System vapor pressure, Absolute load value, Hybrid battery pack life, Engine oil temperature, Engine fuel rate, Torque, VIN & Various DTCs.
