Inductive Proximity Sensor LJ12A3-4-Z/BY Features A proximity sensor is a sensor able to detect the presence of nearby objects. The inductive proximity sensor LJ12A3-4-Z / BY has three pins, two of which are connected to a supply voltage of 6 to 36V. The output pin is PNP and NO (Normally Open). That is, it is normally Low and when it detects an object, it is HIGH. The detection distance is 4 mm and it can only detect metal objects such as copper, aluminum, iron, etc. Note Because the operatio...

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 ...

TLP281 4-Channel Opto-isolator IC Module Features Sometimes we need to separate the low-voltage section (microcontroller) from the high-voltage one in circuit in order to prevent noise and damage to the microcontroller. This module isolates the low-voltage section from the high-voltage section using TLP281-4 IC. This IC contains 4 LEDs (Light Emitting Diode). 4 high-voltage channels can be controlled by microcontroller using this IC.This module can also be used to turn on and off the servo motor and oth...

LJ12A3-4-Z/BX Inductive Proximity Sensor Features Proximity sensors are used to detect the presence of nearby objects. The LJ12A3-4-Z / BX sensor has three pins, two of which are connected to a supply voltage of 6 to 36 V. The output pin is PNP and NO (Normal Open). That is, it is normally Low and when it detects an object, it becomes HIGH. The detection distance is 4 mm, and it can only detect metal objects such as copper, aluminum, iron, etc. Note Since the operation voltage is more than 5 V,...

L298P Motor Driver Shield Features Today, DC motors are used in the manufacturing many tools and equipments. So, speed and direction control of these motors is very common. A half-bridge circuit is one of the simplest methods to control a DC motor. This method not only controls the motor direction, but also can be used for speed control. This shield is based on L298P IC. The most important features are: Control two DC motors simultaneously with voltage 4.8 to 24V and up to 2A current Schottky diodes ...

TTP223 Capacitive Touch Sensor Features The TTP223 sensor can be used in a variety of applications such as smartphones and tablets. The sensor can recognize objects even from behind glass and thin surfaces. The operating voltage is 2 to 5.5V. The maximum response time is 220 milliseconds. This module has two non-soldered adjustment pins: A and B. The working modes are as follows:A and B both open: The default value of the output pin is LOW. When the sensor is subjected to touch, the output is HIGH, and...

TTP229 Capacitive Touch Keypad Features Keypads are one of the most popular components that are widely used in electronics. Everybody can communicate with different systems by switches. Normally, every key occupies one digital pin of the microcontroller. But by using a 4x4 keypad you can reduce the occupied pins. With this module, you can use all 16 switches by occupying only 2 pins of the microcontroller. This 16 key capacitive touch keypad is based on the TTP229 IC. Output pins 1 to 8 are for direct swit...
