The Smartec SMTIR99XX infrared sensors are sophisticated devices containing silicon infrared sensors and thermopiles. Thermopiles are structures composed of thermocouple junctions and convert thermal energy into electrical energy. The application of thin film technology allows the production of miniaturized and low cost sensor elements.
The SMT172 is a three-terminal integrated temperature sensor with a duty-cycle output suitable for microprocessor reading, while retaining analogue information. Available in various encapsulations and as a naked die, it offers high accuracy (0.1°C in -20°C to +60°C range) making it ideal for human-centric applications like climate control. For easy integration, online applications are available, and a specially designed Smart Temperature Acquisition System allows low-cost, high-accuracy measurements, even driving cable lengths up to 20 meters for remote sensing.
The Smart Pressure Device SPD series of pressure sensors are silicon based and encapsulated in all kind of housings. The pressure range can vary between about 10 mBar and 20 Bar gauge, absolute and differential. In case of the absolute version, the reference vacuum chamber is formed on the die during manufacturing.
The Universal Transducer Interface (UTI) converts sensor signals into time signals, eliminating the need for extra electronics and outputting in a digital format for micro-controllers. While the UTI operates in 16 modes and requires a matching reference element for accuracy, the newly introduced UTI Evaluation Kit USB simplifies measurements and offers modules for infrared sensor voltage porting.
The Smartec humidity sensor is a two terminal capacitor, which increases in value as water molecules are absorbed into its active polymer dielectric. The capacitor consists of a base plate and a water permeable platinum top plate.
The MUXC01 multiplexer is specifically designed to work with the Smartec Universal Transducer Interface (UTI). The combination of the UTI and the MUXC01 makes it possible to measure multiple capacitances with a very low capacitance value and a very high accuracy (15 bits).
This list of notes enables you to understand Smartec products better and make it easier to get good and fast results.
