Infrared CO2 Sensor SKU: SEN0219 PWM - Analog mode

I bought this sensor https://www.dfrobot.com/product-1549.html . It says it is analog, but it also says it is PWM (i didnt see this before).

There is any change that i could do, to make it work in analog mode? Or could i get the analog signal from any place in the board? I understad that i could damage the sensor.

I notice that the sensor could work in uart mode, analog mode or PWM mode. 

Please let me know if this is possible.
