Suggestions about waking ESP8266 up

				Hello~
I want to send information to the server when the light changes (turns on or turns off). As for now, I have a photoresistor connected to ESP8266's ADC pin.(Click  ESP8266 to see more details or buy it)  I'm measuring voltage and sends information to a server when it changes much. ESP stays always on.

However, I'd like to make it in slightly more energy efficient way.

The sensor will be used in a bathroom, so the light is usually turned off.

Perhaps I could make ESP8266 wake up somehow by photoresistor and then send a request to the server and wait for the light to turn off back again and then send the second request and enter the deep-sleep mode? Or maybe there is a better way?

I'm seeking help in creating a circuit. What should I use? How the circuit should look like?
