The QRE1113 breakout board offers a digital output solution, utilizing a capacitor discharge circuit to assess reflection levels. This compact board is designed for line sensing applications, particularly suitable when only digital I/O pins are available in the system. It is compatible with both 3.3V and 5V systems, providing versatility in various...

Wireless proximity sensor activated magnetically. The device is used mainly to determine the position of doors and windows. Case dimensions - 11 x 16 mm.

Wired proximity sensor activated magnetically. The device is used to determine the position of doors and windows. Case dimensions - 20 x 64 mm.

The 40kHz 16mm ultrasonic sensor can detect objects in a certain area and gives the distance value between the sensor and the object. The sensor has an operating frequency of 40 KHz. 40 KHz signals propagate as sound waves in the direction of the target, and the reflected waves are detected by the sensor. Then, the distance measurement is made by...
