0.1°C Accuracy Digital Temperature Sensor

MMS Electronics can improve product temperature accuracy by using the Smartec SMT172 digital temperature sensor.

The SMT172 sensor provides clinical-grade temperature measurement accuracy (0.1°C) with fast response time to temperature changes. The SMT172 is a digital ultra-low power, factory calibrated, high accuracy temperature sensor with pulse width modulated output signal. PWM output sensors have high noise immunity and high reference accuracy. The sensors are easy to interface and multiplex. The SMT172 duty cycle output is proportional to the measured temperature. Inaccuracy of the T018 package sensor is ±0.1 ºC between -20ºC to 60ºC and 0.4ºC to -45ºC and +130ºC. Max temperature that can be measured with the sensor is +130ºC. Designed for supply voltage from 2.7V to 5.5V. This is the most energy efficient temperature sensor in the world with an average current of < 60uA or 220nA based on 1 measurement per second. The ultralow power consumption of the sensor minimises the self-heating effect. Different sensor packages are available to suit the application including a 5mm and 7mm stainless steel probe with cable. For fast development evaluation boards with USB and I²C Interface are available (SMTAS04 and SMT172toI2C).

Application are found in biotechnology, wearables, IOT, scientific, environmental and medical measurements.
