The HS-2000DD is designed for direct digital interface to monitoring or control system microprocessors. This sensor operates with a single supply voltage of 2.0 to 5.5 volts and can draw its supply from a standard microprocessor I/O pin. The wide supply voltage range and low power consumption make this device ideal for battery-operation. The output is designed for simple and effective communication to microprocessors in OEM and custom systems. Based on capacitive-polymer technology, this socketed device is factory calibrated, eliminating the need for field re-calibration or difficult calibrations in OEM applications. RH measurement is accurate to 2% with excellent stability.
