How the mass air flow sensor is tested In modern cars, the only way to test the mass air flow sensor is with a scan tool. Mechanics measure the amount of air flow (mass air flow sensor readings) at different RPMs. They compare the readings to the specifications or to the readings of ...
You can imagine how this same type of sensor could act as a smoke detector. If it ever got smoky enough in the store to block the light beam sufficiently, the bell would go off. But there are two problems here: It's a pretty big smoke detector. It is not very sensitive. There ...
The speed of fans on a device is adjusted based on heat dissipation of the device, that is, the temperature of each temperature sensor on the device. According to the fan speed adjustment algorithm, if the temperature at the monitoring point of the temperature sensor increases, the fan speed...
The best way to clean keyboard keys is to first use compressed air to remove loose debris, then clean between keys with cotton swabs dipped in isopropyl alcohol. For deeper cleaning, you can carefully remove keycaps and clean underneath, but check your keyboard’s manual first as some keyboard...
Check Engine light: what to check, common problems, repair options Code P0171 - System Too Lean: symptoms, causes, common problems, diagnostic Mass Air flow Sensor (MAF): how it works, symptoms, problems, testing Codes P0301-P0308 Cylinder Misfire Detected: symptoms, common problems causing ...
So as I had in 2018, I opened a chat window to HP tech support and was able to make my case without having to perform yet another reinstall of Windows–because the fingerprint sensor was kind enough to fail during the chat. The rep’s response: “Looks like this could be a hardware ...
1. Airflow is obstructed. It is possible that a clogged lint filter is causing the excessive moisture sensor heat generated by the dryer. Follow these steps to ensure that your dryer continues to operate at peak performance: Remove the lint filter and thoroughly clean it. Remove any lint or...
To ensure that the air coming out of the barrel never nears this temperature, hair dryers have some type of heat sensor that trips the circuit and shuts off the motor when the temperature rises too much. This hair dryer and many others rely on a simple bimetallic strip as a cut off ...
In this area, use the infrared sensor to maintain the low brightness of light when nobody passes through, even 0% brightness at somewhere out of the way. When someone passes through, the light automatically turns on; after they leave the area, the light turns off a few seconds later. Cer...
developed a robot sensor probe that fits into standard cabinets. Therobot moves up and down a belt-driven railinside the cabinet to collect temperature data for each rack. It then transmits the data via Bluetooth to connected devices so data center pros can create a full heat map of...
