HTU(F) 3800 Humidity & Temperature Transducer

Brand: American Sensor Technologies Inc
Based on the new digital humidity module HTU3800 Series are dedicated humidity and temperature plug and play transducer designed for OEM applications where reliable and accurate measurements are needed. 

Direct interface with a micro-controller is made possible with the module humidity and temperature digital outputs. HTU3800 Series modules are designed for high volume and cost sensitive applications where power consumption is critical. 

Every module is individually calibrated and tested, linearized signals in digital, I²C format. Furthermore, the resolution of HTU3800 Series digital humidity and temperature module can be changed by command (8/12 bit up to 12/14 bit for RH/T), low battery can be detected and a checksum improves communication reliability. 

Optional PTFE filter/membrane (F) protects HTU3800 Series digital humidity modules with temperature output against dust, water immersion as well as against contamination by particles. PTFE filter/membrane preserves a high response time. Several connectors are proposed. 5 Vdc or 3 Vdc power supply products are available.
