AM2302 (DHT22) Temp & Humidity Sensor

High-Precision Capacitive & Thermal Sensing: Integrates a capacitive humidity sensor element and high-precision NTC thermistor for superior accuracy over basic DHT11 modules.

Integrated Signal-Conditioning Breakout: Pre-mounted on a compact breakout board equipped with an onboard pull-up resistor and power decoupling capacitor for quick, solderless setup.

Calibrated Single-Bus Digital Output: Transmits pre-calibrated digital telemetry across a single signal line, conserving valuable GPIO pins on host development boards.

Broad Environmental Measurement Window: Accurately measures relative humidity from 0% to 100% RH (-+2% - 5% RH) and temperature from -40°C to +80°C (-+ 0.5°C).

3-Pin Header Breakout Layout: Standard 0.1" pitch male headers (VCC, GND, DATA) allow direct connection with Dupont female jumper wires to microcontrollers.

Board Material: High-grade FR-4 glass-epoxy breakout PCB with white protective sensor housing and soldered 3-pin header connector.

Technical Specifications:

Input Power: 3.3V – 5.5V DC.

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

Humidity Measurement Range: 0% – 100% RH (-+ 2% - 5% RH accuracy).

Data Interface: Single-bus Digital Signal.

Board Color: Red PCB with White Sensor Casing.

Usage Advice: Connect VCC, GND, and DATA pins directly to your microcontroller; use standard DHT.h libraries in Arduino IDE, ESPHome, or MicroPython for instant readings.

Maintenance: Keep the white sensor ventilation grill clean from dust buildup and avoid using in direct liquid immersion or condensing environments.

Essential High-Accuracy Climate Breakout: Position as an easy-to-use breakout module upgrade over standard entry-level sensors for weather stations, Home Assistant nodes, and HVAC controls.

Highlight Onboard Pull-Up Advantage: Emphasize how the onboard pull-up resistor simplifies breadboard prototyping by eliminating extra discrete components.

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