    Good and cheap PIR Module

    posted by MurrayB on 08/04/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    There is no documentation for it. Google HC-SR501. You can connect CdS light sensor in it. It has two potentiometers and jumper pads so you can setup to suit your needs.
    Cons:
    Would be nice if a datasheet was available. But you don't really expect that from these kinds of assembled components. Google H...

    Value for Money

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Very useful for low voltage electronic projects. Cannot be connected the wrong way around as the connectors are polarised. Good length on cables. Nothing wrong with these connections. Good value for money.
    Cons:
    Nothing bad about these cables. Everything is good and value for money.

    Nice warm colour

    posted by MurrayB on 03/14/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Warm white SMD LEDs. There are actually three LEDs in each module. Easy to solder to. They have good light output at low current of approximatly 10mA. This is the third packet of these LEDs I have bought from DX
    Cons:
    Best if glued and then soldered onto a printed circuit board.

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Easy to solder wires to. Low resistance contacts. I have bought many packets of these connectors and used them for battery connections. They easily handle 10amps without heating. Simple packaging.
    Cons:
    Nothing observed. It would be nice if half of the supplied heatshrink was Red instead of all black.
