what is an electronic sensor?

Question

an electronic sensor switch

Answer 1

An electronic sensor is a device that takes a real-world value (e.g. pressure, temperature, etc.) and converts it to either a variable resistance or voltage (analog sensor) or a variable length pulse (digital sensor).
An electronic switch is an electronic sensor with a logic circuit directly attached to it to perform a specific action at a specific value from the sensor.

Answer 2

It depends on the application. There's not much information to go by. An electronic sensor switch to my knowledge would be a switch that senses engine temp and when it goes over 220º F an electric fan comes on to cool it down. Photocells react (switch) when a different light intensity is presented to its surface.

Answer 3

Car computer use sensor (water temp sensor, air temp sensor, knock sensor, rpm sensor), to make fine tune / adjustment on the fly. In the old days, mechanics would tune the car and they would be static. If the car would fall out of tuning, it would need manual "tune up".

Basically modern cars use sensors to tune the car little by little during use. Also the reason why modern cars don't need tune up. What they call tune up is basically air filter, spark plug, and maybe ignition wire, etc. Not really tuning.

Answer 4

there are many types of sensors.some measure resistance,some read pulses,some measure voltage.
