PIR motion sensor (HC-SR501) false results with …

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 it. So may be because NodeMCU heatness triggers it. Some hot air blow near it. But I don't know.

How to Use PIR Sensor with NodeMCU ESP8266 ...

PIR sensor modules will work with both and 5V levels. Thus, it is safe to connect the VCC pin of the PIR sensor to any of the of the NodeMCU. The GND pin, of course, connects to the GND pin of the NodeMCU. The OUT pin connects to any digital pin of the NodeMCU. This pin will go low when the sensor …
