How to connect mq131 sensor to electron board?

Hardware

i have ozone sensor mq131 datasheet is https://www.sainsmart.com/sainsmart-mq131-gas-sensor-ozone-module-for-arduino-uno-mega2560-r3-raspberry-pi.html.

this sensor works on 5V dc and has analog output proportional to gas concentration but electron has 3.3V reference voltage for analog channels

does sensor o/p can be connected to electron pin?

If your sensor may output more than 3.3V you need to map that output value into the 3.3V range (e.g. via voltage divider)
