Sensors are used to detect things, such as motion, light, or color.
Strain gage based sensors are mostly used.
It depends what kind of sensor you mean. There are lots of sensors in trains already... for such things as heat/smoke detectors, doors (which stop the train moving unless the doors are closed, fuel, signal sensors..... etc
The sensors that an engineer puts on a robot are entirely dependent upon the functions that the engineer perceives that the the robot will be called upon to perform. Some, but not all, of the sensors may be: proximity sensors, pressure sensors, light sensors, magnetic sensors, a camera, temperature sensors, accelerometer, speed sensor... The question isn't, "what sensors does a robot have", but rather, "what sensors does the engineer think that the robot should have?"
sensors for mechanics
They don't have sensors.
type of sensors used in aeroplanes
Strain gage based sensors are mostly used.
There is no vss on a 2012 Charger. The abs sensors and transmission sensors are used for vehicle speed.There is no vss on a 2012 Charger. The abs sensors and transmission sensors are used for vehicle speed.
Parking sensors are used to alert drivers of unseen obstacles during parking maneuvers. The parking sensors that are currently used by car producers are electromagnetic sensors and ultrasonic sensors.
IR and RF sensors
Motion sensors and surveillance cameras are used in basic security surveillance.
CO2 sensors in houses are used for detecting when there is too large of an amount of carbon dioxide there is in a house. These sensors go off and the fire department comes.
Infrared laser sensors that can detect movement.
Infared sensors are used in security systems to help trigger movement. This can be used to notify someone if there is an intruder.
Torque sensors are used in vehicles and aircraft. They are used on engines, gearboxes, crankshafts and transmissions to measure the amount of torque being generated.
magnetic sensors and state where they might be used.
