LPS331AP Sensor Pinout This sensor has 9 pins. 4 pin are more useful:+5V: Module power supply – 5 VGND: GroundSLC: I2C ClockSDA: I2C dataYou can see pinout of this module in the image below. ...

HN3808-AB Rotary Encoders Features A photoelectric rotary encoder is an electromechanical device that has an internal shaft inside a cylindrical space that looks like an motor. The circular plate inside it has two slits. An optical transmitter sensor is located on one side and an optical receiver sensor is located on the other side. When a gap is placed between the two sensors, the sensors and finally the receiver are connected to the microcontroller. Rotary encoder is commonly used to determine the positio...

Double-sided Touch Sensor Features There is a wide variety of touch sensors. One of these sensors is double-sided touch sensor with 3-pin and 4-pin interface on each side. Pin N in 4-pin interface is not used. Note Pin S is always HIGH and changes to LOW if the switch is touched. (If not touched, it will be HIGH again.) Double-sided Touch Sensor Pinout This Module has 3 main pins:VCC: Module power supply – 3.3/ 5 VGND: GroundS: Sensor output (5V)N: Not us...

SR602 PIR Motion Detection Sensor Features PIR or Passive Infra-Red sensors detect motion based on infrared light of ambient heat. PIR sensors are commonly used in security alarms to detect the presence of human. The SR602 sensor is able to detect movement up to a distance of about 3 meters. This sensor has a digital output. When it detects motion, output will be High and it last 2.5 second. After that it returns to LOW. Note You can adjust sensitivity and HIGH time duration usin...

Dot Laser Diode Module Features This module emits a small intense focused beam of visible red light. This module can be used in laser toys, wireless telecommunications, signal equipments, etc.Operating voltage: 5VRequired current for module to be turn on: Less than 40mAOutput power: 5mWLaser wavelength: 650nmWire length: Max 120mm Note Since the required current is less than 40mA and the Arduino pins can supply this current, so this module can be connected directly to Arduino. If it were more ...
