Why the information collected by the sensor can't be read by computer directly?

A computer cannot read data from sensors directly because the signals received from the sensors come as analogue signals which, a computer cannot read. It requires a converter to convert the signals in to digital signals so the computer can be able to read it.


Is a sensor an input?

Yes, anything that serves the same function as one of your five (or six) senses is an input device.Any type of sensor is an input device.Anything that reads is an input device.Anything that scans is an input device.Anything that sees (still camera or video camera) is an input device.Anything that hears (microphone or recording device) is an input device.Anything that "feels" (temperature sensor, humidity sensor, rain gage, or anything with buttons, like a keyboard and a mouse) is an input device.Anything that "tastes" or "smells" (smoke detector, CO detector, raydon detector, chromatograph, etc.) is an input device.In contrast, anything that makes you use your senses is an output device, including (but not limited to)...speakersmonitorsprintersdevices controled by the computerSome devices serve as both input devices and output devices, ibnlt...hard drive, thumb drive or other data storagetelephonecopiermodemnetwork router

What is an O2 sensor high voltage bank 1 sensor1 On a 1997 dodge ram truck 1500?

The oxygen sensor reads the amount of oxygen in your exhaust to calibrate your air/fuel mixture. If it reads a higher voltage, the sensor is telling the pcm that you are running rich. Your sensor could be bad or need cleaning. Start with the inspection of the oxygen sensor for carbon deposits and the wire for any pinch or melting. Since it is a 97 you probably need to replace it anyways.
