Pull up resistor with PIR Motion Sensor. - SparkFun ...

· Not all PIR sensors have the same output or even output type. A pull-up resistor is needed when the output type is what's known as a "open collector" (or open drain). These type outputs use a transistor (or a FET) to produce a short circuit to ground, generally when the PIR detects something. When there's no detection, then the transistor is an open circuit and that leaves the Arduino input pin …

Properties of the signal pin on a PIR sensor - Arduino Forum

· I have connected such a module to a 5V Arduino board, and I used "pinMode(2, INPUT_PULLUP) ;". The internal pullup resistor helps the signal to get a little higher. Adafruit connects a led to the pir output in the tutorial : https:///pir-passive-infrared-proximity-motion-sensor/ Perhaps the PIR module sold by Adafruit can do that. I don't know if every PIR module can …

Motion and Light Sensors with Arduino (PIR sensor)

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 non-Arduino version!

Problem with HC-SR501 PIR Motion Sensor -

· But you also then need a resistor (say 10k) between the Arduino ground and its digital pin 2. My edit should have been better as: Remove the sensor. Put a 10K pull down resistor between pin Arduino 2 and ground. Touch a wire between Arduino pin 2 and the Arduino 5 volt pin to simulate the action of the sensor detecting something.

Pull-up resistor value for PIR + 10 M cabling - Arduino Forum

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

· No resistor should be needed on the digital output of a PIR. It seems that the transmitter of that neoway module triggers the PIR sensor. Nothing you can do about that, apart from some distance between them. You could ignore a PIR trigger during transmitting (and about 3 seconds after that) of the neoway module. Make sure the "time" (Tx) pot is ...
