A Passive Air Temperature Sensor is used to measure the temperature of the incoming air. This information is required for the engine control unit (ECU) to make precise adjustments to the air-fuel mixture, ignition timing, and other parameters. By accurately sensing the air temperature, the sensor helps the ECU adapt to varying environmental conditions, contributing to improved fuel efficiency, reduced emissions, and engine reliability.Attributes:• Provide real-time temperature readings and trigger specific actions based on the temperature level• Provided with a supply current of 4mA, which is beneficial for energy efficiency Applications:A Passive Air Temperature Sensor acts as an input device that provides real-time air temperature data to the ECU, ensuring optimal combustion, engine performance, and efficiency.
