HC-SR501 PIR Sensor Sensitivity and Time Delay is adjustable

There are two potentiometers onboard.

One is to adjust the sensitivity, and the other is to adjust delay time.

Also there are two trigger mode. One is Single trigger mode, which means that delay is started immediately upton detecting motion, and continued detection is blocked. The other is Repeatable trigger mode, timely delay is re-started every time motion is detected.

Customers say

Customers like the value and ease of use of the motion detector device. For example, they mention it's a good product for the price, easy to connect and use, and simple. That said, opinions are mixed on quality, sensitivity, and performance.

AI-generated from the text of customer reviews

18 customers mention18 positive0 negative

Customers appreciate the value of the motion detector device. They mention it's a good product for the price, and a great low cost motion sensor.

"...It's awesome, gives me so much more control and cheaper. I do get some false-positives, but not nearly as much as with the pre-built unit...." Read more

"Nice PIR sensor and good price for 5. Well packaged, all 5 work...." Read more

"Great price, amazingly sensitive and reliable...." Read more

"...like the more quality sensors like you'd get at Sparkfun BUT they're cheap and 4 out of 5 worked (3 out of 5 worked well)." Read more

8 customers mention8 positive0 negative

Customers find the motion detector easy to connect and use. They also say it's simple and works well.

"This is probably the most common PIR sensor available. It's easy to use, and quite sensitive...." Read more

"These work great, and are easy to hook up and adjust. One of the five didn't work, but for the price I still think its a great deal...." Read more

"...Very easy to hookup with ample code available on the net. I have these hooked to an ATTINY85 programmed to turn on when motion is detected...." Read more

"...They seem to detect motion well and hookup is really easy...." Read more

4 customers mention4 positive0 negative

Customers find the motion detector device fun to fool with.

"...Overall, it has worked out great and was a fun little project. However, the adjustment pots seemed to be too sensitive...." Read more

"...Love um....a lot of fun to fool with." Read more

"Great little sensor. Fun projects to try. Solid device." Read more

"...They all worked well right out of the box. Fun to play with if you like to mess around with Arduino projects." Read more

70 customers mention41 positive29 negative

Customers are mixed about the performance of the motion detector device. Some mention that it works well, is perfectly good for most applications, and has a delay. Others say that it acted erratically, is unreliable, and is not the most powerful PIR.

"Was intact and serves well in my project long lasting too." Read more

"...It's awesome, gives me so much more control and cheaper. I do get some false-positives, but not nearly as much as with the pre-built unit...." Read more

"These are good PIR sensors for Arduino projects. The adjustments are really sensitive, the smallest adjustment makes a pretty big change...." Read more

"Hooked the VCC and ground to a 12v A/C adapter and it worked perfect...." Read more

15 customers mention9 positive6 negative

Customers are mixed about the sensitivity of the motion detector device. Some mention that it can be adjusted for sensitivity, has a very wide sensitivity pattern, and is amazingly sensitive. They like the adjustability, saying that the smallest adjustment makes a pretty big change. However, others say that they had hard time adapting, the adjustment pots seemed to be too sensitive, and it seems to trigger on the lowest sensitivity for no discernible reason.

"These are good PIR sensors for Arduino projects. The adjustments are really sensitive, the smallest adjustment makes a pretty big change...." Read more

"Seems to trigger on lowest sensitivity for no discernible reason. Lost a lot of time trying to figure out why. Junk." Read more

"...Very wide sensitivity pattern. Tho description says "< 100 degrees" I thought it was greater than 120...." Read more

"...I tweaked and tweaked and it just seems like there isn’t fine adjustment. The motion detection was either too sensitive or not sensitive enough." Read more

13 customers mention5 positive8 negative

Customers are mixed about the quality of the motion detector device. Some mention it's good quality, solid, and reliable, while others say that it produces way too many false alarms.

"...Running them even SLIGHTLY under 5v may cause repeat false triggers (i.e. "flashing" on/off on the output signal)" Read more

"Was intact and serves well in my project long lasting too." Read more

"...However, it is useless and give LOTS of FALSE POSITIVES...." Read more

"They're okay for what they are, cheap...." Read more

5 customers mention2 positive3 negative

Customers are mixed about the responsiveness of the motion detector device. Some mention that it's very responsive with a nice range, while others say that the delay is a little long and the recovery time is not nearly long enough.

"...Wanted it for lights to get from car to back door. Ten seconds is not nearly long enough...." Read more

"This product is perfect, and I love that it has a delay. I can wire this up to a board as-is without building a delay circuit myself...." Read more

"...Unreliable. There is also an annoying four second delay before motion can be detected again." Read more

"...They seem to detect motion well and hookup is really easy...." Read more

Good PIR sensor
These are good PIR sensors for Arduino projects. The adjustments are really sensitive, the smallest adjustment makes a pretty big change. They work good for my chosen application.
