Any interest in an ambient light sensor that can readily interface to your EZIO2X4, EZIO8SA or EZIO6I?? It would have the following specs:
– Spectral response matching the human eye – not a cheap photocell!
– Analog output readily interpreted by the EZIOxx – Alarms could be set to send INSTEON group commands at preset light levels
– A separate digital output with a level settable by a built-in potentiometer
– Small box (about 1.5″ X 1″ X .75″)
– Under 15 bucks
How would you use it? What applications come to mind?Mitch@MDHMemberNovember 20, 2008 at 11:06 pmPost count: 29
I use a light sensor (analogue output 0 – 5 VDC) to change response status of some lights in the house where good lighting is more critical. I put the sensor in an upstairs hall where it reads light levels coming in through a skylight. On a sunny day there is enough ambient light to work in the kitchen or office, but on cloudy days it can be pretty dark. My controller reads the analogue input and will turn on lights in the office and kitchen in response to a signal from an occupancy sensor (hard-wired motion sensors) if the light level is below a particular threshold (adjustable from a user-friendly touchscreen interface). I could imagine this would work well with an installation where your controller or software was able to send “then” commands based on multiple “If” conditions (e.g., light level, occupancy, etc.).
