At the top of this post there is a second photo.  What is it?  An enclosure for the sensor and antenna?

Also, Cozir mentions the sensor has a light sensor?  Is it an LDR?  Does anyone know?

Thanks,

You could contact the manufacturer ...  IIRC from the datasheet not all models support this (not sure)

I asked for ldr functionality in my sensor and was told it wasn't being supported anymore, the datasheets haven't been updated to reflect this. The ldr was an optional extra, so at order time you are just told the ldr isn't available. I liked the idea of an ldr, but i think these sensors are being targeted to the commercial sector (handheld devices) where an ldr might not be as useful as opposed to the arduino/electronics community where having one sensor do many things is desirable depending on what you are making. ldrs are 10 a penny so just hook one up along side the cozir, thats what i did.

The enclosure is from proto-pic.co.uk, it was lying around so i put it together and the antenna is connected to a bluesmurf module, it has a decent range with the antenna.

Does the cozir sensor still has a connector for the LDR?

This is disappointing.  I thought I had found a sensor that would do so much. I am wondering if there are any with all four sensors as Cozir has stated in the documentation.

I would like to create a sensor module that will sense C02, temperature, humidity, light and motion and connect them all to an xbee network to stream on the Internet. 

Is PIR a good sensor for motion?  What is a good precision LDR? 

I plan to place these modules on each floor of my home to detect variations in temperature and humidity, alert on C02 and motion, and adjust an LED to shed light in the room as it is needed.

Thanks,

Thomas
