Hi, can i ask question about EEPROM?...Can EEPROM store some settings, such as an Buzzer, Flame Sensor , Wifi Details and LED code. Example if our IOT project are lose power and reboot, it can running / working well like ESP8266 Wifi Module can connect our default Wifi again and also Buzzer, Flame Sensor , LED code smoothly.

Our IOT Project are like Application Fire Alarm using Wifi, like sending data value Flame Sensor from IOT Project to Our Application Fire Alarm (Phone). Our Application Fire Alarm (Phone) can give notification to user about Fire Has Been Detected.
