Try an operating range of -40°C to +150°C. Google for the datasheet. Though the easiest to implement, the response time for the T0-92 package may slower than you need. Thermistors and thermocouples are faster.As far as i know, LM 35 can be used for room temp measurement only.....can i make use of LM35 ??
Thermistors (RTD) require more calibration to implement than the LM35.How about RTDs?
