Reliable motion detection
I've tested several PIR modules, and this one offers the best stability. No false triggers from pets or temperature changes so far. The dual potentiometers for time and sensitivity are very handy.

Perfect for my home security prototype
This PIR sensor works flawlessly with my Arduino Uno. The detection range is impressive, picking up movement clearly across my living room. The adjustable delay potentiometer makes it very versatile for different applications.

Easy integration
Plug and play with standard Arduino libraries. The output signal is clean, making code implementation straightforward. Highly recommend for anyone starting with IoT sensors.

Great value for learning projects
Bought this for a university robotics project. It's sensitive and easy to wire up. I deducted one star because the included jumper wires were a bit short for my breadboard setup, but the sensor itself is excellent.

Best beginner sensor
As someone new to electronics, this module was incredibly forgiving. Plenty of tutorials online work perfectly with this specific board. Very happy with the purchase.

Solid performance
Works as described. The 120-degree angle covers a wide area. Just make sure to give it a minute to calibrate after powering on, or you might get a few initial false positives.
Q: How do I switch between repeatable and unrepeatable trigger modes?
A: There is a small jumper cap on the PCB labeled 'H' and 'L'. Place the cap on 'H' for repeatable triggering (output stays high while motion continues) or 'L' for unrepeatable (single pulse per detection).
Q: Does this come with a mounting bracket?
A: The package includes the sensor module and jumper wires. It has two screw holes for mounting, but a specific bracket is not included; however, it fits standard M3 screws easily.
Q: Is the output voltage compatible with 3.3V logic boards like ESP32?
A: Yes, when powered by 3.3V, the high-level output is approximately 3.3V, which is fully compatible with ESP32 and other 3.3V microcontrollers.
Q: Can this sensor detect motion through glass?
A: No, PIR sensors cannot detect infrared radiation through glass. The lens must have a direct line of sight to the moving object for accurate detection.
Q: What is the maximum current draw of this module?
A: The module typically draws less than 60uA in standby mode and around 65uA during active detection, making it suitable for battery-powered projects.
