P-008: Laser sensor module This Keyes device is one of the more common devices found in Arduino sensor kits. Coupled with other components, it can be used to create trip wires or optical effects. The KY-008 is particularly neat because it can be directly powered from an Arduimore...
Rotary Optical Encoder is a sensor that converts machinery positional information into corresponding pulse numbers or digital data by photoelectric signals. Therefore, it can detect the speed, position, angular velocity, distance and counts information relating to mechanical machmore...
