Very handy little PIR circuit

This small Chinese PIR circuit DYP-ME003 is available on the market in different versions.
The version offered is obviously currently.
It is easily connected to 12V because it is supplied to an internal 3.3V voltage regulator HT7133-1.
Main IC, the circuit BISS0001. PIR sensitivity and time can be adjusted well.
An LDR (light sensitive resistor) is provided only.
In Test A 3mm Phototransistor L-93dp3bt of Völkner showed good results.
PCB and solder have a good quality.
With a externern power transistor, the board will now go my 12V LED strip to the fullest satisfaction.
