ESP12e Single analog pin connected with multiple sensors

Hi I'm new with Arduino and Esp12e. Is it possible to connect one analog pin to multiple MQ gas sensors?. Can someone help me for My struggling

Do a site search on 'analog multiplexer'.

Analog multiplexer is one option; an external ADC such as the ADS1115 is another - the latter works over I2C, offers four analog channels, and you can connect a number of them on a single I2C bus for even more analog inputs.
