During today's session i have decided to research some of the Arduino sensors
IR Infrared Obstacle Avoidance Sensor Module
"used in robots to detect objects near the sensor. These sensors have a digital output pin that outputs a signal when it detects an object. When the module detects an obstacle, the green indicator light on the board lights up. The module detects the distance 2 ~ 30cm, detection angle 35"
The IR transmitter sends an infrared signal that, in case of a reflecting surface (e.g. white color), bounces off in some directions including that of the IR receiver that captures the signal detecting the object.
When the surface is absorbent (e.g. black color) the IR signal isn’t reflected and the object cannot be detected by the sensor. This result would occur even if the object is absent.
Microphone Sensor
This sensor is used for sound detection. This module has two outputs: AO (analog output), or DO (digital output). The digital output sends a high signal when the sound the sound intensity reaches a certain threshold. The threshold-sensitivity can be adjusted via potentiometer on the sensor.
Rotary Encoder Module Brick Sensor Development Board
When you rotate the rotary encoder it counts in the positive direction and the reverse direction. Rotation counts are not limited. With the buttons on the rotary encoder, you can reset to its initial state and start counting from 0.
