CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...

SW-520D Vibration Tilt Sensor Features The SW-520 sensor consists of two metal balls which switches as a trigger. When the switch is positioned horizontally, and when the sensor angle is less than 10°, the circuit is open (off state) and more than 10°, it is closed (on stated). But when the switch is positioned vertically, the circuit is open when the sensor angle is less than 45°, and close when the angle is more than 45°. To see exactly how this sensor works, read the datasheet. The SW-520D sensor is ...

ULN2003 Stepper Motor Driver Features We usually use stepper motors when we need precise control of the motor shaft. These motors can be used in robot arm, 3D printers, CNC machines, etc. 28BJY-48 is a kind of stepper motor. In full step mode, these motors have a 1 to 64 speed reduction gearbox and eachfull 360 degree rotation consists of 32 steps. The ULN2003 driver is commonly used to control these motors. ULN2003 IC consists of 7 pairs of Darlington transistors, each pair can withstand 500mA and 50V. Th...

GY-31 TCS3200 Color Sensor Features The TCS3200 color sensor uses 64 photodiodes to detect color. The output of this sensor is a square wave. Color intensity is obtained directly from the frequency of the square wave. These 64 photodiodes consist of 16 diodes with red filter, 16 diodes with green filter, 16 diodes with blue filter and 16 transparent photodiodes without filter. All 16 diodes of each type are connected in parallel. To detect any color, the photodiodes corresponding to that color are activ...

Single Axis 1:120 Gear Motor Features If you work in electronics and robotics field, you have come across DC motors at least once. These motors are one of the most widely used elements in electronics and robotics. These motors convert direct current electrical energy into mechanical energy.An external source provides power for the stator of these motors. As a result, the current flowing through the stator creates a uniform field under the poles. Of course, permanent magnet can supply the stator field, ...
