How it works

3 stages · Explore one step at a time

Step 1 / 3

Select the measurement

At address 0x44, send 0x2400 for a high-repeatability single conversion without clock stretching.

Step 2 / 3

Wait for completion

At 3.3 V, allow the 15 ms maximum conversion time before reading. Lower supply operation has a longer bound.

Step 3 / 3

Validate and scale

Check both CRCs, then scale the unsigned raw words into Celsius and percent humidity.
