AM2305 I2C digital temperature & humidity module

I2C Digital Bus Interface: Communicates using a standard I2C digital output interface, enabling multi-device telemetry architecture and easy integration with host microcontrollers.

Calibrated Composite Digital Signal: Combines a polymer capacitive humidity sensor element and an NTC temperature measuring element with an integrated 16-bit high-performance MCU.

Industrial Protective Outer Enclosure: Encased in a rugged, ventilated ABS protective probe shell with pre-wired connection leads for enhanced physical protection in demanding environments.

Wide Range & High Measurement Accuracy: Measures ambient relative humidity across 0% to 99.9% RH (-+ 2% RH) and temperature from -40°C to +80°C ( 0.3°C).

Long-Distance Telemetry Stability: Onboard digital signal processing ensures strong signal anti-interference and stable data transmission over extended cable distances up to 20 meters.

Housing Material: High-impact ABS protective probe enclosure with flexible insulated lead cables.

Technical Specifications:

Operating Voltage: 3.3V – 5.5V DC.

Temperature Measurement Range: -40°C – +80°C (-+ 0.3°C accuracy).

Humidity Measurement Range: 0% – 99.9% RH (-+ 2% RH accuracy).

Communication Protocol: I2C Bus.

Color: Black Protective Casing with Multi-Color Cable Harness.

Usage Advice: Ensure pull-up resistors (4.7 kΩ - 10 kΩ) are enabled on the SDA and SCL lines; match the 3.3V - 5V power rail to your host system logic level.

Maintenance: Keep the central ventilation mesh clean and free from oil residue, heavy dust accumulation, and condensing liquids to maintain fast thermal response times.

Essential Ruggedized I2C Probe: Position as an industrial-grade, plug-and-play digital probe for HVAC systems, automated greenhouses, environmental control cabinets, and long-range IoT sensing nodes.

Highlight I2C Reliability & Weather Resistance: Emphasize how the I2C digital output combined with a protective casing provides a significant upgrade over basic breadboard-style climate sensors.

Recommended Cross-Sell Add-ons: Pair with AM2301 (wired DHT21) temperature-humidity sensor, AM2302/AM2302B Single-bus Digital Temperature & Humidity Sensor, GY-SHT30 3.3V Digital Temperature & Humidity Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
