Efficient Motion Detection for Electronics

Great product for electronics enthusiasts. The module provides an efficient and reliable motion detection system that is highly sensitive and accurate. The installation process is easy, and its compact size works well with limited space. The only downside is that it may not be suitable for larger rooms as its range is somewhat limited. Overall, a highly recommended security and surveillance solution for electronics.

Pros
  • High sensitivity and accuracy in detecting movement and heat changes, making it ideal for security systems or automation systems.
Cons
  • Sensitivity to temperature changes may lead to false alarms or detection of non-human objects such as pets or moving trees or bushes.

Great compact PIR sensor!

Great little sensors that work reliably for what I use them for. The sensor is fairly compact (10mm diameter) and is great if you're short on space. Solder pins and wire directly onto the board if you need an even smaller size. I use them with an Arduino Nano clone to turn on LEDs.

Pros
  • Motion detector
Cons
  • There are other interesting options.
