Pin Functions ( ):

VDD: Power Positive (2.4V-5.5V DC). External 0.1µF filter capacitor recommended.

GND: Power Ground. Connect to system common ground.

SDA: I²C Data Line (Open-Drain). Requires external 4.7kΩ pull-up resistor.

SCL: I²C Clock Line (Open-Drain). Requires external 4.7kΩ pull-up resistor.

ADDR: I²C Address Select (VDD = 0x45; GND = 0x44).

ALERT: Over-Limit Alarm Output (Open-Drain, Active Low).

nRESET: Hardware Reset (Active Low, Internal Pull-Up if Floating).

FAQ Highlights:

1.
No Data Output?

Verify voltage (2.4V-5.5V). Check SDA/SCL pull-up resistors (4.7kΩ). Confirm I²C address (ADDR pin level).

2.
Humidity Deviation >3% RH?

Avoid condensation. Keep away from PCB heat sources for accurate readings.

3.
I²C Communication Failures?

Shorten bus length (
4.
ALERT Pin Not Triggering?

Program threshold register (command 0x6100 via I²C). Add external 10kΩ pull-up to VDD.
