AP3216 Sensor Features The AP3216C is an integrated ALS & PS module that includes a digital ambient light sensor [ALS], a proximity sensor [PS], and an IR LED in a single package. This module is well suited to applications under clear glass or darkened glass. The proximity function is targeted specifically towards near field application and detects external object with simple configurable zone controlled by registers.  Note You need a 220 to 470 ohm resistor to interface this module. ...

Grove Touch Sensor Features This sensor uses TTP223-B IC. When your finger approaches this sensor, the capacitance of the metal surface will change. So you don’t need to touch sensor completely. Besides, you can put this sensor under a non-metallic surface and touch it. This sensor is waterproof, and it has a variety of applications.  Note There are two red and black wire that have been connected to this sensor. If you want to increase the fingerprint sensitivity, you can remove the black w...

E18-D80NK Infrared Obstacle Avoidance Sensor Features The E18-D80NK sensor is used to detect obstacles and objects. This sensor works based on transmitting infrared rays. First, the transmitter sends the rays in a direct path. This ray hits the obstacle and returns to the receiver. There is a potentiometer on this module that can be adjusted to change this detection distance from 3 to 80cm. In fact, with this sensor, the obstacle can be detected, but the distance cannot be calculated directly. There is also...

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...

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...

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,...
