Two PIR13’s arrived yesterday. I immediately unpacked them to see if they would fit in the enclosure I want to use for them. It fits, but there’s not much room for error.
The lens is larger than the one on the previous PIR I used; this one requires a 13 mm hole, the previous was 10 mm. And the PIR13 lens sticks out more then the Panasonic version. But still, i prefer this much more than the X10-RF motion sensors i used in my former life 🙂
The PIR13 PCB is glued to the top plate with hot glue. As you can see there’s not much tolerance along the long sides of the PCB; if the hole through the top plate is a bit excentric, you’ll have a hard time to make it all fit right. So pay attention there!
One nasty thing happened to me while preparing the 1st PIR13 to fit in the box; i decided it was wise to get rid of the 3 headers that are sticking out of the PCB; they were much to long! So i took my soldering iron and tried to get those things out. Normally, when you remove the plastic piece of the header and hold the soldering iron against a pin, they automatically fall out, sometimes with a bit of help, or they stick to the soldering iron. This time it was different; as if the pins were rammed into the PCB with a hammer! So i used a pair of pliers to gently pull the pin out; and while doing that, i damaged the PCB in a way that can’t be repaired anymore; aarggh!! First a voltage regulator blown up, now this.. what is this??
With the 2nd PIR13, i just cut off half of the pin length…
I foresee a “battle” for my spare time, between the LED strips and this new motion sensor… 🙂
