Weekly Progress
This week, I have storage the data of sensor. Measured temperature from 26°C to 202°C , all 3
time. I have resistance of temperature while working on. But I can't using resistance sent to the
microcontroller. I have using voltage divider circuit because microcontroller used it to work. I have
use 3 resistors in voltage divider circuit, the 3 resistors can regulator scale voltage 0.5 v to 4.5 v.

temperature of sensor
Engineering Analysis
Strong Point
- Use the voltage drop of resistance from sensor sent to microcontroller.
- Storage the data of sensor, measured temperature from 26°C to 202°C.
Week Point
- The sensor non-linear.
Next Week Job
- Circuit design by program for PCB.
- Test and run for the circuit
