What the 1.5% accuracy means at temperature
The HS3001: With a 6 ms response time, the sensor tracks humidity transients faster than most HVAC damper actuators can respond, meaning the reading is the bottleneck, not the sensor.
I²C integration and supply rails
The 1.8 V supply rail aligns with low-power MCU domains, avoiding a separate level translator for the I²C lines in most 1.8 V logic systems.
Package and board-fit note
Supplied in strip form, surface-mount package — reflow-solder compatible with standard lead-free profiles; no special bake-out required for MSL-rated moisture-sensitive devices unless the strip has been exposed beyond the floor life.
