CAN bus - Wikipedia

High-speed CAN signaling drives the CANH wire towards V and the CANL wire towards V when any device is transmitting a dominant (0), while if no device is transmitting a dominant, the terminating resistors passively return the two wires to the recessive (1) state with a nominal differential voltage of 0 V. (Receivers consider any differential voltage of less than V to be recessive.)

CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation ...

How 5-Wire Sensors Work (Tech Edge) -

Narrowband sensors have between one and four wires. One of the wires will always be the signal voltage. A second wire can be used to isolate the ground end of the signal to reduce signal noise. Three and four wire sensors add a heating element so the sensor starts operating faster and more reliably.

FAQs | Alphasense

Oxygen sensors generate a current which is proportional to the rate of Oxygen consumption. This current is easily measured by placing a load resistor between the cathode and the anode (the 2 pins on an Oxygen sensor) and measuring the resultant voltage drop. This load resistor should be between 10 and 100Ω (we recommend 22Ω or 47Ω).
