how about the ph sensor sir?AMS1117 can’t supply high current, especially when Wi-Fi is active. Use a dedicated 5V 2A adapter instead of USB power or boost conversion.
Check if the ESP8266 boots (LED blinks) and connects to Wi-Fi. Also, check your wiring. For the DS18B20 and ESP8266 part, you can follow the tutorial.
