esp8266 - PIR motion sensor (HC-SR501) false results with ...

The issue is the PIR sensor that comes with ESP8266 can work with as well as 5V. By default, the wiring is connected to the 5V which may work fine for the Arduino device but not for ESP8266. I just removed the red cable (power cable) from the connector and connected to the other side where you can see H. That side also there are 3 pins. Remove the jumper completely and connect to the ...
