Temperature Sensor DIY for calculators

[Csaba Tizedes]

Hello,

Have anybody experience with homemade temperature sensors measuring inside the electric owen how the temperature is changes around the setpoint?

I want to make this measurement up to 250-300 degC and if possible using thermistor connected to a calculator as a data collector unit?!

It is possible to collect and save data on a pocket calculator (time and temperature)? The electronics is how complicated if I want to use similar technology like Vernier on TI 83/84Plus?

Thank you for the answers!
