Product Parameters Input Voltage: 4.4V-5.5V DC (Wide Voltage Compatible) Humidity Range: 0-100% RH (Non-Condensing) Humidity Accuracy: ±2% RH (Typical @25°C) Temperature Range: -40°C to +125°C Temperature Accuracy: ±0.2°C (Typical @0°C-90°C) Resolution: Programmable (Humidity: 0.007-0.020%; Temperature: 0.012°C-0.040°C) Response Time: Humidity 3s (T63%), Temperature 10s Communication: I²C Interface (Up to 400kHz, Address 0x40/0x41 Configurable) Power Consumption: 1.04µA (Operating @1Hz), 0.13µA (Standby) Protection: IP67 Optional (With External Filter) Package: 6-Pin DFN (2.5mm × 2.5mm × 0.9mm) Pin Functions VDD: Power Positive (4.4V-5.5V DC) GND: Power Ground SCL: I²C Clock Line (Requires 4.7kΩ Pull-up to VDD) SDA: I²C Data Line (Requires 4.7kΩ Pull-up to VDD) RST: Hardware Reset (Active Low, >1μs Pulse) IC_ADD: Address Select (GND=0x40, VDD=0x41) FAQ 1. Humidity Drift >3% RH? Run self-calibration: Send command 0x30,0xA2 to activate heater for 30s, wait 10 minutes, then resample. 2. I²C No Response? Verify: IC_ADD pin level matches address (default 0x40 requires GND). VDD ≥2.4V (avoids under-voltage sleep). SDA/SCL pull-up resistors (4.7kΩ to VDD) are present. 3. Abnormal Data in High Humidity/Temperature? 4. Extend Battery Life? Use single sampling mode (command 0x2C,0x06) and set interval to 60s (sleep current: 0.13µA). 5. CRC Errors? Keep SDA/SCL wires away from power noise. Add 10µF + 0.1µF capacitors to VDD. Reduce I²C clock to 100kHz .
