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 (8/12bit up to 12/14bit 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. 5VDC or 3VDC power supply products are available.
