Yes, you will need an ADC, the Pi has no analogue inputs or outputs.

A popular choice would be an MCP300X (10 bit resolution where X is the number of channels) or MCP320X (12 bit resolution). They connect via the Pi's SPI bus (GPIO 7-11)

You will find plenty of software and tutorials for those chips and the Raspberry Pi.

  • You need an ADC for analogue sensors. The DS18B20 is a digital sensor. – joan May 24 '17 at 12:34
