20210506· A logical approach, is to "condition" the signal at the Arduino end with a 10k resistor after the pullup, and a 5µF capacitor. Rather than altering the pullup, it would make more sense at the sensor, to use a 10k pullup and a 74HC14 with one inverter feeding the other five in parallel, as a buffer. youngengineer October 24, 2014, 6:20am 4

PIR sensor is a special type sensor which is usually used for security purposes. It detects the objects by reading the Infrared radiations emitted by the objects. Any object whose temperature is above absolute zero, emits radiation. This radiation is not visible to human eyes.
20201009· The main components of the Automatic Room Lights project are Arduino, PIR Sensor, and the Relay Module. Out of the three components, the PIR Sensor is the one in focus as it is the main device that helps in detecting humans and human motion.

This simple Arduino sketch does just that. A light dependent resistor is connected to an analog pin on the Arduino, and reading from it will either trigger the light (if it’s dark) or have the Arduino check for motion by reading from the motion sensor connected to a digital pin (if it’s not dark). And finally… a nonArduino …
