Tutorial: How to use the HCSR505 PIR sensor with the ...

+

30/8/2017· PIR (Pyroelectric InfraRed) sensors measure infrared (IR) light that is radiating from objects in the detection area. The HCSR505 is such a sensor. It very easytouse as it already delivers a HIGH signal if something is moving in the detection area. This HIGH signal lasts about 8 seconds, which is sometimes seen as a disadvantage. Unfortunately, […]

Step 4: Let''s Start Coding. The code is very simple, and is basically just keeps track of whether the input to Digital pin D7 is HIGH or LOW. It also tracks the state of the pin, so that it prints out a message when motion has detected or not. int Status = 12; // Digital pin D6 int sensor = 13; // Digital pin D7.
