Very cheap and relient item. I am surprised as sensitive it is. I like it and would order more for other projects involved motion detection. Easy to use motion detector with variable sensitivity and variable output-High time (2 sec ... few minutes).
Doesn't has a CDS cell for to disable operation when ambient light levels are high. Board could be smaller If device so small - they should use SMD capasitors It would be great to have digital in\out on it - I2C...
with these prices I might need to build more PIR sensor lights for my house.
