Radar detectors are designed to pinpoint the presence of radar and laser sensors that police and law enforcement use to calculate your driving speed—hopefully in time to help you avoid getting a ...

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 ...

Abstract: A laser gas sensor with phase compensation in free space is designed based on a half-mirror and mixer in this study. The half-mirror is employed to split the returned beam into transmitted ...

Abstract: A 4-probe laser interferometric displacement sensor (4pLIDS) has advantages over a single-probe LIDS in a micro-thruster calibration system. By synchronously measuring the displacements at ...

Hello Hackers! Today we have a really interesting topic. Searching the internet, I didn't find any simple solution on "How to read data from car parking sensors," so I decided to write a short and ...

This GitHub project implements an HTTP web server on an ESP32 board that serves an HTML page displaying readings from a BME280 sensor, including temperature, humidity, and barometric pressure. The ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...
