HIH-4000 Humidity Sensor

HIH-4000 is a linear humidity sensor from Honeywell. 

HIH-4000 humidity sensor is an industrial grade sensor specially designed for high volume OEM users. Since the output of the sensor is linear analog voltage it is possible to directly give the output of the sensor to Analog to Digital Converter (ADC) or a controller with internal ADC. The Sensors sensing element's multilayer construction provides excellent resistance to most application hazards such as wetting, dust, dirt, oils and common environmental chemicals thus making it suitable for rugged industrial applications.

HIH-4000 humidity sensor has a capacitive sensing element and delivers instrumentation quality performance. The HIH-4000 does not require any external calibration or trimming to provide typical accuracies. The HIH-4000 low drain, linear output, and precise calibration make’s interfacing very easy to any micro-controller
