Motion detection

Post by **Post-IT** » Fri Sep 18, 2009 4:23 pm

I looking at several motion detection solutions, for which I could use some advice.

I have an RFXCOM 433 Tranceiver and a PMIX35 in my current setup.

Options:
1) MS16A sensors, seems large, not white, not sure if this works with my current setup (USA stuff), price seems ok.
2) MS90, compact and sleek design, white, price is high (55), works with RFXCOM, not sure if this sensor measures light level
3) Z-Wave HSM100, needs an extra Z-wave stick, Euro version adds an additional $11 per sensor, compact and sleek design, white, temperature sensor, battery level, choosing US version limits additional Z-wave products in the future to US only, integration with HS looks nice

My goals is to measure movement and lighting levels, temperature is a nice addon, but I already have a bunch of Oregon sensors around the house where needed. These triggers will be used to activate several scenarios (lights, locks, HVAC and more). Speed is also important, if lights switch on after 1 or 2 seconds it's too slow.

Small form factor and design is important, I don't like tawdry or ugly enclosures hanging around. Especially because I'm looking at about 10 sensors.

Does anybody have any other ideas, or thoughts on this?

I use MS16a's around the house. They are quite small (6,5cm x 6,5cm x 2,5 cm) Although they are not white the design is OK. I bought an extra 310Mhz RFX receiver and it works fine. You can also rebuilt them to 433 Mhz but on motion they send an on signal every 7 seconds so a lot of traffic on 433mhz. Light (KAKU) switches on within 0,5 second (310 Mhz on signal => Homeseerevent => 433 on signal to Kaku. My opinion: Cheap, Small, good lookin...

I have the RFXcom LAN+WLAN transmitter+receiver, doesn't this mean I don't have space left for an extra receiver (310Mhz) because I have the transmitter in that spot?

And do you have any advice on where to buy the MS16a's?

I was told that in the Lan version there is a device that gives too much distortion on the 310 Mhz antenna, therefore you need to put the 310Mhz receiver in a USB casing, away from the LAN tranceiver. I bought the MS-16a's on ebay at big johns place. If you buy the MS16A's you might as well buy some DS10A's. They cdon't cost much either.

Thanks!

Weird guys those eBay sellers, gives a $40 discount on the hardware, but increases the shipping costs with $20. I thought combined shipping was cheaper.
