FUNCTIONAL DESCRIPTION
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 volt and the third terminal carries the output signal. This output is standard microcontroller compatible and can be connected directly to most processors.

By measuring both T1 and T2, the temperature can be easily computed from
T1/T2 = 0.32 + 0.0047 * t (°C) (the diagram right).
If the output signal is measured with an analogue device, the temperature can be obtained as well. The mean voltage (and the RMS value as well) is directly proportional to the duty cycle and the supply voltage. So Vout / Vdd represents T1 / T2 just as well.
In this way the temperature can be measured in an analogue way as well as digitally equally simple and accurate.
