j'en ai commandé 3 trois pour un prix dérisoire, fonctionne parfaitement, je recommande
Received in <2 weeks. Works well.
buon sensore di movimento, abbastanza sensibile e la gamma è impressionante considerando le sue dimensioni ridotte.

Module works ok except if trying to add a CdS light sensor to the RL connection points. Pin 9 on the chip should be high impedance but on these modules appears to have a 12k ohm connection to Vdd. Tested by cutting track to pin 9 to isolate the pin and measuring resistance between pins 9 and 11 - result was 12k! Faulty chips?
I bought 6 of these for a robot directional-response project. They work really well. Detects people or animals every time. The adjustable sensitivity is very useful to tailor it to your specific application.
