dual zone prox sensor and wifi
I believe that dual zone proximity sensors operate in the microwave frequency, can anyone see a problem with this given that the wifi signal operates in the microwave frequency.
Do they interfere with each other?
"microwave frequency"? There's not just one frequency. Your microwave oven operates at a frequency near that of an 802.11b/g device, but the microwave band is generally considered to be somewhere around 1GHz and up. If the proximity sensor is up in the 10-30GHz range like police radar guns and automatic door opening sensors, you won't have a problem. Best way is to find the FCC ID on the proximity sensor, and look it up in this database: https://gullfoss2.fcc.gov/prod/oet/c...ericSearch.cfm
That will give you info on the device including what its operating frequency is.
