I have a PIR sensor which I use to detect the motion and turn ON and OFF the lights on the basis of it. I have PIR connected with NodeMCU (ESP8266) based board. I find that sometimes it trigger false positive value. Even when there is no motion. As per my understanding I think any of the following reasons can be there: I have NodeMCU close to ...

IoT Motion sensor Working Theory. We have connected the PIR motion sensor to one of the GPIO pins of the NodeMCU ESP 8266. Whenever the PIR detects motion then the output sates of the PIR sensor will change which will be detected by the controller. We have programmed the NodeMCU to make an HTTP GET request to our IFTTT webhooks applet.
