The PIR sensors use the detectors or pyroelectric sensors to work. Example include the automatic door openers.
piezo electric principle
The principle of operation of any known sonic sensor (the human ear, for example) is detection of air vibration by measurement of its sensitive membrane oscillation frequency.
based on the pizoelectric effect. Change in resistance due to the force acting on it and convert it into 4 - 20 mA.
Sensor 1 (before the catalytic converter) adjusts the fueling based on sensing if the engine is burning fuel rich or lean. The post-converter sensor detects if the converter is operating properly by looking for a difference in readings
it principle denpend on what kind of flow meter. example, magnetic flow meter, it use magnetic force to measuring or coriolis flow meter which is use vibrated capilary tube as sensor. or more info you might watch on youtube.
A simple test to know if the car computer is working.?æ Identify your sensor and turn on the ignition to see if the sensor confirms the car's computer.
Speed Sensor is not working
how to tell if my crankshaft sensor is not working
Your motion sensor light may not be working due to a variety of reasons, such as dead batteries, a faulty sensor, or a power outage. Check the batteries, sensor settings, and power source to troubleshoot the issue.
if it does not work
The Keurig water level sensor not working issue could be caused by a malfunctioning sensor, a clog in the water line, or a problem with the electrical connections.
