Pololu Digital Distance Sensor 100cm Shipping:2-4 Weeks the chip inside MiFare classicThis small lidar based distance sensor detects the presence of objects within 100 cm (39) . It has a single digital output that drives low when an object is being detected; otherwise, it is high. It works over an input voltage range of 3. 0 V to 5. 5 V, and the 0. 1 pin spacing makes it easy to use with standard solderless breadboards and 0. 1 perfboards. Overview This compact sensor is a great way to quickly detect the presence of nearby objects. As
