· Hi, I’m putting together a project that will have several PIR motion sensors. When movement is detected in the area the system will trigger relays and turn on related strands of high powered LEDs. Right now I’m using a delay(x) to set the pin high but the problem is during the delay time the PIR isn’t sensing. I want to set this up so if someone is moving in the area they will constantly ...
When in non-repeatable mode, the time delay begins immediately after detection and the next motion will be disregarded. It is worth mentioning that when the DOUT pin goes low after the time delay period, there is a 3 second window in which all motion will not be detected. Here’s an example timeline if the HC-SR501 PIR sensor is set to non ...
· Ideally you need a set of Normally Open contacts on your pir, so when it detects an object, the contacts close and triggers the timer. Here is a Monostable timer with a 555 Rt 47K and Ct 22uF set the delay, put your pir contacts on the circuit on the right to prevent further triggering when timed out. View attachment 127668
You can adjust the sensor sensitivity and delay time via two variable resistors located at the bottom of the sensor board. For connecting follow the given schematics as shown in the pictures. It is a small circuit to incorporate a delay to a PIR motion sensor that activates a spray that releases compressed air to drive away birds, cats, dogs etc. The detail is that once the sensor is activated ...

· Howdy, I have a PIR sensor and simply want to have a green LED light up when there's motion detected, otherwise have a red LED light up. I have that part working, no problemo. However, it seems that when I move my hand in front of the sensor, and then move it away, the PIR still thinks the motion is there for a slight delay (a second maybe).

PIR adjustment If the flood light is on, it should go out within approximately 15 seconds. Adjust the LUX setting up until the flood light switches on, staying on for 15 seconds again. Adjust the SENS control to the halfway position and move around in the detection area to check that the flood light is actuated.
The output of PIR motion detection sensor can be connected directly to one of the Arduino (or any microcontroller) digital pins. If any motion is detected by the sensor, this pin value will be set to “1”. The two potentiometers on the board allow you to adjust the sensitivity and delay time after detecting a …
· Resetting the motion sensor only takes a few minutes, requires no tools, and anybody can do it. Turn off the circuit breaker that powers the motion sensor light for a minimum of 30 seconds, then turn it back on. Turn the light switch on, turn it off for two seconds and turn it back on again. Then, how do you trigger a PIR sensor?
PIR Motion Sensors. PIR motion sensors, ... In Configuration -> Configure Module menu change GPIO13 to Switch1. If there already is a Switch1 simply choose the next in line. Same applies if you're connecting more than 1 PIR on a single device. A configured PIR will not appear in the web UI in any form. To make it report like a sensor we need a rule that will send movement triggers to an MQTT ...
· Accordingly, how do you adjust the delay on a PIR sensor? Imagine you're in the single trigger mode (see below) and your time delay is set 5 seconds. The PIR will detect motion and set it high for 5 seconds. After five seconds, the PIR will sets its output low for about 3 seconds.
PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.

· I'm working with a raspberry pi and two PIR motion sensors, HC-SR501 specifically. I'm trying to cut down the time delay on each sensor - the amount of time before motion can detected again, but I can't seem to do better than ~5 seconds, which is way too long for my purposes.
· It is a small circuit to incorporate a delay to a PIR motion sensor that activates a spray that releases compressed air to drive away birds, cats, dogs etc. The detail is that once the sensor is activated, it will be inactive for 5 or 10 minutes (this will prevent it from being retriggered during that time). For space reasons (the PCB must have 2 "x ") I have been trying to do it using only ...
· Likewise, people ask, how do you adjust the delay on a PIR sensor? Imagine you're in the single trigger mode (see below) and your time delay is set 5 seconds. The PIR will detect motion and set it high for 5 seconds. After five seconds, the PIR will sets its output low for about 3 seconds. During the three seconds, the PIR will not detect motion.
