| TECHNICAL TEMPERATURE AND HUMIDITY MODULE 1 DATA HTF 3130 Based on the rugged HTS2030SMD humidity sensor, HTF3130 is a dedicated humidity and temperature transducer designed for OEM applications where a reliable and accurate measurement is needed. It features a very small size for easy, cost-effective mechanical mounting. Direct interface with a micro-controller is made possible with the module's linear frequency output. MAIN FEATURES G G G G G G One of the smallest humidity / temperature modules on the market. Stable,proportional frequency output from 0 to 99% RH. Calibrated within +/- 3% RH @ 55% RH at 5.00 VDC. High quality thermistor Stable characteristics with temperature. High reliability and long term stability. HUMIDITY SENSOR SPECIFIC FEATURES G G G G G Instantaneous de-saturation after long periods in saturation phase. Fast response time. High resistance to chemicals. Not affected by water immersion.

The actual characteristic of an NTC thermistor can, however, only be roughly described by the exponential relation,as the material parame ter B in reality also depends on temperature. So this approach is only suitable for describing a restricted range around the rated temperature or resistance with sufficient accuracy. 1 NTC resistance in at temperature T in K NTC resistance in at rated temperature in K Temperature in K B value,material-specific constant of the NTC thermistor Base of natural logarithm (e =2.71828) 2 For practical applications a more precise description of the real R/T curve may be required. Either more complicated approaches (e.g the Steinhart-Hart equation) are used or the resistance/ temperature relation as given in tabulated form. The below table has been experimentally determined with utmost accuracy for temperature increments of 1 degree.
