Abstract: Pyroelectric infrared sensors (PIR) are excellent devices to detect human/animal presence with a small form factor and rugged design, for cost-effective surveillance. They are widely used to ...

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Another day, another fresh batch of Nintendo Switch 2 reports that combine to form an ever-clearer picture of Nintendo’s next-gen console. After IGN went hands-on with Genki’s high-profile Nintendo ...

The PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...

Laser ranging has many applications in production and life, such as ranging, positioning, obstacle avoidance, and so on. Time-of-Flight (ToF) ranging, as a type of laser ranging technology, is often ...

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 ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...
