Image is Representational - See Manufacturer Specs | This Integrated Circuit Humidity Sensor from Honeywell comes from their HIH-4000 Series of Humidity Sensors. The sensors come in a solderable lead pitch SIP (Single In-Line Package) and this device has a 2.54mm pitch (0.1inch) and leads are 0.1 inch (2.54mm) SIL pitch. The HIH-4000 series of humidity sensors have potential applications in refrigeration equipment HVAC equipment medical equipment and battery powered systems. The Honeywell HIH series humidity sensors provide instrumentation quality RH relative humidity sensing in a solderable Single-In-Line package. The HIH-4000-003 Humidity Sensor is a thermoset polymer sensing element that is laser-trimmed for improved interchangeability. Humidity sensors are used to provide an indication of the moisture levels in the environment and are very useful for industry processes. They are used in a variety of applications such as refrigeration equipment HVAC equipm
