A sensor that is activated by a lack of light (the dark). Usually these can be found in night lights that turn on when the lights are turned out.
oxygen sensor
analog sensor
A sensor that measures flow and pressure of the fluid in a hydraulic system.
A limit switch turns on or off when the object being sensed reaches a specific location.A proximity sensor returns an analog signal indicating how far the object is from the sensor.
basically sensorless scheme estimated the speed using current signal or current sensor without considerartion speed sensor thats reduce the cost of machine and make it more efficient ..basically sensorless scheme can uses sensor only at current signal or sensor at dc link in doubly fed machine,.........................
You can Buy this swich sensor at electrical lighting shop , this sensor can you fit at the bulb holder and you have to place this in open area.with this sensor your light will switch on when dark in your area.
the sensor is in the post behind the drivers door at the bottom , this sensor turns your headlights on in daylight mode when car is started but it is not the sensor that turns them on brighter ( or the dash lights ) automatically when dark
Because motion sensors sense the movement of light, so if its dark, it cant see.
A Infrared proxity sensor i believe.. Some would say an optical sensor also
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
For the newest kind of robot, the light sensor is used to detect the white lines from the dark lines on the nxt this helps your robot follow the lines!!
It's a sensor that "tells" the lamp that it's getting dark
it uses infared and heat sensor to make a visible image
The daytime running light (DRL) module may be defective. If the lights are activated by the sensor at all, that eliminates the DRL fuse from being faulty.
Most vehicles use a light sensor to detect the ambient light level and automatically turn on the daytime running lamps when it gets dark. This sensor is usually located on the dashboard or near the rearview mirror.
The knock sensor is located on the front of the engine, just above the oil filter mount. It should have a single Dark Blue wire connected to it.
To effectively utilize a plug-in light sensor to automate lighting in your home, first plug the sensor into an outlet near the light you want to control. Adjust the sensitivity and settings of the sensor to detect when it is dark and trigger the light to turn on. Position the sensor in a location where it can accurately detect changes in light levels. Test the sensor to ensure it is working properly and adjust as needed.
