I'm wondering if using about 150 ESP8266 in same area will generate a problem.
I'm working on a project of "parking lot avaiability" using ESP8266 and ultrasonic sensors. The parking have about 150 lots, but don't know if exposing all those crowded modules will saturate the signals and produce interference.
Maybe, ESP8266 will not be a good solution. Any recomendations or suggestions?
