Actually there are many temperature sensors in the market. You may browse the internet (some famous IC companies) to check your sensor requirements. If you want to pass the value of the senor to the MCU, you may try some digital temperature sensor.

i support the idea of using amicrocontroller to solve the problem but you could just design an adder using an op amp to sum the output of the sensors and takingone foyrth of the output using a potentiomete
