Engine knock is the sharp, metallic sound that cuts through the hum of a healthy engine. At its core, engine knock is a problem of timing. In a knocking engine, parts of the air-fuel mixture don't ...

What is the knocking sound coming from my engine? What is engine knock? Why is my engine making a knocking noise? Engine knock, or pinging, occurs when a separate pocket of air-fuel mixture ignites ...

Yeckel] recently put the finishing touches on an ambitious implementation of a simple D-STAR (Digital Smart Technologies for Amateur Radio) transceiver using some very accessible and affordable ...

Having an AI assistant is all the rage these days, but AI assistants usually don’t know about your automation setups and may have difficulty dealing with tasks asynchronously. Enter zclaw.

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

The MV300 detects the direction and strength of the 3D (X, Y, Z) magnetic field. The signal from Hall sensors is amplified and converted to digital signal. The magnetic field range can be scaled from ...

Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

Abstract: This paper introduces a highly sensitive, rapid, and low-cost sensing method for online analysis of engine oil quality and predicts the exact time of oil expiration. The multi-mode optical ...

Abstract: In the automotive industry, the study of internal combustion engines (ICE) has massively been studied to identify the occurrence of some failures, such as engine knock [1], [2]. The ...
