GENERAL INFORMATION The HIH-3605 monolithic IC (Integrated Circuit) humidity sensor is designed specifically for high volume OEM (Original Equipment Manufacturer) users. Direct input to a controller or other device is made possible by this sensor’s linear voltage output. With a typical current draw of only 200 mA, the HIH-3605 is ideally suited for low drain, battery powered systems. The HIH-3605 delivers instrumentation quality RH sensing performance in a low cost, solderable SIP (Single In-line Package). Available in two lead spacing configurations, the RH sensor is a laser trimmed thermoset polymer capacitive sensing element with on-chip integrated signal conditioning.
NIST CALIBRATION HIH-3605 sensors may be ordered with a NIST calibration and sensor specific data printout. Append ‘‘?CP’’ to the model number to order. RH SENSOR CONSTRUCTION Sensor construction consists of a planar capacitor with a second polymer layer to protect against dirt, dust, oils and other hazards.
The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESD-induced damage and/or degradation, take normal ESD precautions when handling this product.
