ema flow sensors
sensors can detect blood flow ,the movements of body and IR sensors can find the temperature of human body
Sensors provide information to other parts of the machine. There are temperature, pressure, level, flow, biosensors, gas, and proximity sensors.
First one
Jeep doesn't use mass air flow sensors.
Flow with the Tide was created in 1991.
The dust particals sticks on the wires where from it sense the flow of air mixture.
Dodge does not use mass air flow sensors on the Intrepids.
IR and RF sensors
Traffic lights typically use sensors such as induction loops, infrared sensors, and cameras. These sensors help detect the presence of vehicles and pedestrians at the intersection, allowing the traffic light to change based on the traffic flow.
Traffic light sensors work by using various detection technologies such as inductive loops, video cameras, or radar sensors to monitor traffic flow at an intersection. These sensors can detect the presence of vehicles waiting at the intersection and communicate this information to the traffic signal controller. The controller then uses this data to optimize the timing of the traffic lights and improve traffic flow.
