Digital Temperature Sensors and the Internet of Things
Learn how digital temperature sensors play a key role in our digital and connected world.
Digital temperature sensors can convert temperature physical quantity and humidity quantity into a digital sensor through a temperature and corresponding circuit. The Temperature System Sensors (TSYS) are available in miniature packages designed specifically for tight spaces, and respond quickly to changes in process temperature. The optimized microcircuit design allows fast conversion times along with very low power consumption.
Digital temperature sensors are commonly used in applications including:
TE Connectivity’s TSYS03 digital temperature sensor series are designed to provide accurate temperature measurements in a miniature (TDFN8) or ultra-small (XDFN6) surface mount package with very low power requirements.
Feature | Analog | Digital |
---|---|---|
Accuracy |
Total system accuracy is the sum of sensor elements and measurement circuitry. ±0.2ºC sensor accuracy typically only ½ of total error budget | System Accuracy ±0.1ºC |
Very Low Power |
Always on voltage divider constantly drains power | Very low-power sleep modes between active sense cycles |
Data Quality Reliability |
Degradation due to contact and lead resistance, noise, A/D conversion, the possibility for erroneous readings | Digital data is either valid or null |
Integration Effort |
External circuitry, coding of lookup tables, system validation | Simple I/O call with straightforward data conversion |
Cost/Accuracy Ratio |
Need sensor, external resistors, stable voltage supply, quality A/D |
Competitive and declining price trend |
Size |
Available in <1mm two-wire configuration | Down to 2.5 x 2.5 x 0.8mm package, die possible for hybrid circuit application |
