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

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 Detector With NodeMCU and BLYNK -

The HW is very simple. The sensor has 3 pins (+5V, GND and Output). It is important to point that the output of the HC-SR501 generates a logic signal of + (HIGH) or 0V (LOW), which is COMPATIBLE with the input levels of the NodeMCU, which also works with the level. I kept the circuit with a level converter to ensure if any other sensor with 5V output is used.
