1wire to 0-5v microcontroler, need code and hardware suggestion

i want you to give me suggestion of hardware and write me programm code.

i want to plug in 1wire temperature sensor DS18B20 in hardware and need software which reads 1wire, which checks that it works and gives out temperatur range -20°C until +40°C in 0,2V - 4,8V. if there is error or sensor has problems he should output 5V.

i pay 100% after finishing whole project successfully.
