The SMT160-30 is a three terminal integrated temperature sensor, with a duty-cycle output. Two terminals are used for the power supply of 5 Volts and the third terminal carries the output signal. A duty cycle modulated output is used because this output is interpretable by a microprocessor without A-D converter, while the analogue information is still available
The SMT160-30 (TO18 model) has an overall accuracy of 0.7 °C in the range from -30 °C to +100 °C and an accuracy of 1.2 °C from -45 to +130 °C. This makes the sensor especially useful in all applications where "human" (climate control, food processing etc.) conditions are to be controlled.
The CMOS output of the sensor can handle cable length up to 20 meters. This makes the SMT160-30 very useful in remote sensing and control applications.
