AM2320 temperature and humidity sensor

Dual Communication Protocol: Supports both standard I2C digital bus interface and 1-Wire single-bus communication protocols for ultimate flexibility across different microcontroller platforms.

Calibrated Composite Digital Output: Combines a polymer capacitive humidity sensing element and an NTC temperature measuring component with a dedicated 16-bit MCU for accurate, factory-calibrated digital signals.

Ultra-Low Power Consumption: Features fast response times, strong anti-interference capabilities, and low power consumption, making it ideal for battery-operated smart home nodes and IoT sensors.

Broad Environmental Measurement Window: Measures relative humidity from 0% to 99.9% RH and temperature from -40°C to +80°C with high stability and resolution.

Compact 4-Pin Package: Housed in a compact 4-pin single-row package (0.1" / 2.54 mm pin pitch) for easy integration onto breadboards, prototyping shields, or custom PCBs.

Housing Material: Durable ABS plastic ventilated protective casing with standard 4-pin male lead legs.

Technical Specifications:

Operating Voltage: 3.1V – 5.5V DC.

Temperature Measurement Range: -40°C – +80°C (-+ 0.5°C accuracy).

Humidity Measurement Range: 0% – 99.9% RH (-+ 3% RH accuracy at 25°C).

Communication Interface: I2C Bus or 1-Wire Single-Bus.

Color: Black Enclosure with Metallic Lead Pins.

Usage Advice: When using I2C mode, connect standard pull-up resistors (4.7kΩ - 10kΩ) on the SDA and SCL lines; ensure proper logic level matching for your target microcontroller.

Maintenance: Keep the sensor ventilation slits clean and free from dust, condensates, or aggressive chemical vapors to prevent reading drift.

Essential Upgraded Climate Sensor: Position as a versatile, low-cost alternative to DHT11 and DHT22 sensors, offering both I2C and 1-Wire digital interfaces on a single chip.

Highlight Dual-Protocol Advantage: Emphasize how the I2C option saves microcontroller timing overhead compared to traditional single-wire bit-banging methods.

Recommended Cross-Sell Add-ons: Pair with AM2302 (DHT22) Temp & Humidity Sensor, AM2302/AM2302B Single-bus Digital Temperature & Humidity Sensor, HTU21D Temperature & Humidity Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
