This page describes the electronic circuitry required to interface to the temperature sensors via a USB connection.

Serial Port Temperature Sensors – USB Hardware Interface

To use the PL2303TA USB-serial adapter with temperature sensors in parasitic mode, connect one or more DS18S20 temperature sensors as follows:

  • red: un-used
  • white: un-used
  • black: connect to GND and VDD pins of temperature sensor
  • green: connect to DQ pin of temperature sensor
