Specially designed digital distance sensor for mini sumo robots and small robot projects. It can detect objects from 40 cm (based on detecting area it can be up to 80cm!) Dimensions are very similar to popular Sharp GP340 distance sensor, moreover JS40F doesn't need any extra resistor, capacitor or board...
Reflective type infrared (IR) sensor that rely on beam reflection of front object.
Works between 3.3V to 5V. At 5V sensor draws 15mA.
Has a reverse polarity protection between voltage inputs (Power & GND)
