These sensors are a great way to quickly detect the presence of nearby objects. It consists of a Sharp sensor module installed on our tiny carrier board for these sensors, which includes all of the external components required to make them work.
The available versions offer three different sensing ranges: 2 cm to 10 cm
There are a few millimeters of hysteresis around the maximum range threshold and no hysteresis at the minimum range threshold. Note that these sensors will only tell you if there is an object within the detection range along their narrow lines of sight.
