Interface PIR Sensor With NodeMCU : 6 Steps (with Pictures ...

Connecting PIR sensors to a NodeMCU is really simple. The PIR acts as a digital output so all you need to do is operate the pin to flip high (detected) or low (not detected). Check out the images for more details. Most PIR modules have a 3pin connection at the side or bottom.


NodeMCU Lesson 13— Infrared Remote Control MQTT « …

· In this lesson, we will connect infrared receiver to NodeMCU, When infrared controller key is pressed, it will send an IR signal,then the receiver will catch these signals and send the IR code to the NodeMCU, the NodeMCU will publish these Messages to MQTT broker.


IR Sensor Interfacing with Arduino Code Step by Step Guide ...

· An Infrared sensor or commonly known as IR Sensor is an electronic device, used to sense the heat of an object and motion of an object. Basically, an IR Sensor can detect Infrared radiation that is not visible with naked eyes. A body when heated radiates infrared light which can be detected by IR Sensor.
