    CAN network, where other units can make use of these readings. In addtition, mini Daqu connects to engine ECU and reads data from it. The data is then transmitted on the Kanardia CAN network. We strongly recommend you to carefully read this manual, before you start connecting mini Daqu unit with your engine sensors.

    — Manual 3.5 Analog Active Sensors Analog Active Sensors Active sensors require external power to operate and provide some active signal. Some sensors require 12 V and some 5 V to operate. These sensors are often used to measure various pressures and, fuel levels, etc. An active sensor has its own built-in electronics, which takes care for voltage fluctuations.
