Hi folks, I have this light sensor, I want it to turn on the
Fan when it gets to a certain lux, thing is, when I put power to it I cannot get any output from it whether the relay is
Activated or not, I even bought another cause I thought the
first one was a dud
Hi Niko, yes it does have a separate component that plugs
Into the white socket, sadly no diagram, but I tried to wire up
The fan using all the different combinations on cn1, cn2, and com, I was expecting it to activate the fan when the light
Reached a certain lux, using my voltage meter, there is no
Output voltage from any of those outputs points, have I bought
The wrong unit?
You need to use an ohm meter to test the outputs.
The middle output is the common on the 3 connection side.
A relay is just a switch, it will not output any voltage unless you apply voltage to the common.
To test that it’s working, use your ohm meter, set to “OHMS”.
