Sensor power supply
A variety of sensors are used in automotive controllers, and these sensors usually require a stable and reliable power supply to ensure their proper functioning. The type of supply voltage depends on the type and design of the sensor, here are some common automotive sensor supply voltage types:
5V: This is the most commonly used voltage in automotive electrical systems. Many sensors, such as temperature sensors, pressure sensors, and position sensors, require a 5V power supply.
12V: 12V is the standard voltage in automotive electrical systems, so many sensors, such as speed sensors, require a 12V power supply.
●Other voltages, in some large commercial vehicles or special application scenarios, may need to use 24V power supply. For example, some heavy trucks and excavators may need to use 24V power supply, etc.
The supply voltage ranges of several sensors are listed below:
●Pressure sensor, power supply voltage range 8V-32V, optional 5V.
●Position sensor, power supply voltage range 4.75V-5.25V, typical value is 5V.
●The speed sensor, the power supply voltage range is 4V-24V, generally 12V.
