Smartec I2C Products
Temperature and Humidity
The SMTH08I is a combined Humidity and Temperature sensor and has a calibrated output. For easy interfacing the digital output is I2C compatible. The temperature as well as the humidity has resp. a 14 and 12 bits digital output.
The on-chip I2C interface circuit make the device easy for interfacing with almost any kind of microcontroller.
Each SMTH08I is individually calibrated in a precision environment. The calibration coefficients are stored into an OTP memory and are used for internal correction and calibration.
The two-wire digital I2C output allows fast system integration.
Due to the very low idle state power( < 1 uA) , this device is of interest for any kind of battery operation.
The completely automatic production method makes it possible to offer the temperature/ humidity module SMTH08I for a very competitive price.
This Smartec absolute pressure sensor has an I2C output. The sensor is compensated for offset, sensitivity, temperature drift and nonlinearity.
The sensor has a range of 600 – 1025 mBar FS. Other pressure ranges can be delivered on request ( 0.3 – 100 PSI).
This Smartec differential pressure sensor has an I2C output. The sensor is
compensated for offset, sensitivity, temperature drift and nonlinearity.
The sensor has a range of 102 mm H2O FS. Other pressure ranges can be
delivered on request (0.3 – 100 PSI).
SMTIRmod09 Infrared Modules
The series SMTIRMOD09 infrared sensor modules are especially designed for OEM applications where infrared radiation temperatures have to be measured. The various modules are based on our SMTIR99XX series of infrared sensors. The different modules have different fields of applications and therefore different fields of view. All the devices have an I2C output for standard interfacing to microcontrollers.
- SMTIRmod09micro – 3Vdc Sensor, Infrared Module field of view 120 degrees, T obj <50 °C
- SMTIRmod09std – 5Vdc Sensor, Infrared Module field of view 70 degrees, T obj <50°C
- SMTIRmod09sil – 5Vdc Sensor, Infrared Module field of view 14 degrees, T obj <300°C
Temperature Sensor & I2C Input to USB Module
The Smart two temperature sensor board has also an input for Smartec I2C sensors.
For the temperature sensors the measuring range is – 45°C up to +130 °C using Smartec temperature sensors and sends the temperature and I2C information as a standard ASCII string. The system is based on a Microchip?s PIC12F629 microcontroller and uses an
FTDI chip interface to connect via USB port to any type of laptop/PC. Via the USB-connection the board is powered. Due to a variety of sensors there are two boards available, one with I2C on 3 Volts and one with I2C on 5 Volts power supply.
Up to 2 SMT160-30 sensors can be connected simultaneously; the software will test the inputs automatically on power up after which it will process only the ones with sensors connected. The measurement will start automatically after connecting the board to a USB port and after configuration of the corresponding virtual COM port. The board will be powered via the computer.
