Description of 🔍 Geekstory HC-SR312 AM312 IR Pyroelectric Infrared PIR Motion Sensor Detector Modules Body Manual Motion Detector for Arduino, DC 2.7-12V (Pack of 5pcs)

★Low power consumption, small size, easy to install. ★It is a digital intelligent automatic control product based on passive human body infrared technology. It has high sensitivity and high reliability and is widely used in various automatic induction electrical equipment. ★Repeatable trigger mode: After the high level of the sense output, during the delay time period, if the human body is active in its sensing range, its output will remain high until the delay after the person leaves, Low level (i.e.: the sensing module automatically delays a delay period after each activity of the human body, and the last active time is the starting point of the delay time). ★ Widely applications: Security Products, the human body sensors toys, the human body sensor lighting, industrial automation and control, etc. ★ How to email us?

Works great for my Arduino projects!

Great compact motion sensors. They are not as sensitive as their larger brothers, especially at a distance, but their compact design compensates for this.

Pros
  • Pleasant
Cons
  • Without automatic

Pretty small and spectacular

Works great as a motion sensor. Good and small. Easy to use. You'll need to add a delay to the software when using this with your project if you want something to stay on longer. They come individually wrapped in a large pouch. No complaints.

Pros
  • Lots of positive emotions
Cons
  • Big and bulky

20% bounce? (but small sample size)

4 of the IR motion sensor modules were fine but 1 seemed to be broken due to a short circuit somewhere. When I connected it to my Arduino nothing would turn on and the Arduino chip itself got hot at the power input. Maybe I'm just unlucky. Like I said the other 4 were fine and luckily I only needed 4 for what I was doing. The fifth was intended as a spare (and I probably needed it). There are no complaints about the buzzer.

Pros
  • While satisfied
Cons
  • There are other interesting options.
