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.
If it's PIR (that's passive infra-red) then think of it as an eye that can only see changes in heat, staring straight forward. Whenever something that's warmer or colder than the background moves in or out of its field-of-vision, the sensor reacts to this change in scenery and trips an alarm.
it's completely dependent on the type of mobile bot, it may use ultrasonic sensors or infra red one's depending on the purpose. e.g. if a simple bot has to turn by 90 degree on detecting an object on the path; it may be resulted by using both IR n ultrasonic sensors depending on the range of detection. how it uses sensors is simple the controller used to design the bot sense the pin on which sensor is connected. As the sensor gives signal, as per algorithm of programming the bot will act accordingly.
The automatic door has a special infrared sensor in which a person walks towards the door then the sensor detects that someone in there, it then activates the electromagnets in the entrance system which allows the door to open at at certain speed.
oxygen sensor
Infrared is heat. When you feel the warmth of a space heater, you feel the effect of infrared radiation. The other uses are motion detection (infrared sensor) and night-vision (live animals have a heat signature, a blurred image, against a colder background at night). ======================
It is a type of sensor that detects infrared and hence cause a variation in resistance.
Gas detection in mines has been around since the creation of mines, Today technology plays a huge part. There are sensor technologies designed to detect almost any gas to which we might be exposed. Some of these technologies include, but are not limited to, infrared and photo-ionization detection.
Haynes makes a manual with the wiring schematic for the O2 sensor on a 1991 Chevy Blazer S10. The manual can be found at most book stores.

JUST LIKE 2 DOTS.
The air intake sensor is a resistor that goes to the PCM. A schematic can be found in a service manual
IF the sensor is part of a switch yes.
