* PWM output is easy to read by the a microprocessor.
* PWM signal is proportional to the temperature.
* Supply voltage 3V, 3.3V, 5V (Voltage range from +2.7V to +5.5V).
* 3 pin sensor, requires only one digital pin. ( Vcc, Gnd, PWM output ).
There is also a 7mm stainless steel probe SMT RVS1802 with the most accurate digital temperature sensor SMT172-TO18 built-in. Supplied with 5m or 2.5m cable.
For quick evaluation of these sensors we have evaluation boards with USB interface. The SMTAS04USB can measure up to 4 x SMT172 temperature sensors and the SMTAS08USB can measures up to 8 sensors with an accuracy of 0.1ºC in the temperature range of -10ºC to 100ºC with a resolution of 0.0015 C. The board and sensors are powered from the USB port or an external DC power supply. The board uses an ARM Cortex-M3 STM32F103 to read the temperature sensors and output the measured temperature Celsius value and the PWM signal in HEX on the USB interface.

This little interface board reads the SMT172 temperature and presents the Celcius temperature value to the I2C bus. The SMT172TOI2C can convert the SMT172 output to be compatible with the older and obsolete SMT160-30 sensor. This allows the board to be used for repair of equipment that use the obsolete SMT160-30 sensor.
