HTU3800 Series Digital Humidity Module With Temperature Output

The HTU3800 Series are dedicated humidity and temperature plug and play transducers designed for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the modules humidity linear voltage and direct NTC outputs. The HTU3800 Series are designed for high volume and demanding applications where power consumption is critical.

Optional PTFE filter/membrane (HTUF version) protects HTU3800 Series analog humidity modules against dust, water immersion as well as against contamination by particles. The PTFE filter preserves a fast response time. 5VDC or 3 VDC power.
