DHT11 Temp & Humidity Sensor

Calibrated Digital Signal Output: Integrates a resistive humidity sensor and NTC thermistor element paired with an onboard 8-bit MCU to deliver pre-calibrated, composite digital signals.

Single-Bus Digital Protocol: Transmits data across a single digital signal pin, minimizing I/O pin consumption on microcontrollers.

Plug-and-Play Breakout PCB: Built on a compact breakout board equipped with built-in pull-up resistors and decoupling capacitors for immediate breadboard and jumper wire connections.

Wide Voltage Supply Range: Operates efficiently from 3.0V to 5.5V DC power, providing direct compatibility with both 3.3V and 5V logic systems like ESP32 and Arduino.

Low Power Consumption: Features fast signal response times and low power draw, making it well-suited for entry-level environmental monitoring nodes.

Board Material: Standard FR-4 glass-epoxy breakout PCB with blue protective sensor housing and pre-soldered 3-pin male header pins.

Technical Specifications:

Input Power: 3.0V – 5.5V DC.

Temperature Measurement Range: 0°C – +50°C (-+2°C accuracy).

Humidity Measurement Range: 20% – 90% RH (-+ 5% RH accuracy).

Communication Interface: Single-bus Digital Signal.

Board Color: Blue PCB with Blue Sensor Casing.

Usage Advice: Connect VCC, GND, and DATA pins correctly according to board silkscreen markings; utilize standard DHT.h libraries in Arduino IDE or ESPHome for quick integration.

Maintenance: Keep the ventilation grill clear of dust and debris, and avoid operating in direct water condensation or chemical vapor environments.

Essential Beginner Environmental Breakout: Position as an accessible, hassle-free starter module for students, makers, and beginners building their first weather monitoring projects.

Highlight Onboard Resistor Integration: Emphasize how the onboard pull-up resistor simplifies breadboard prototyping by eliminating external component wiring.

Recommended Cross-Sell Add-ons: Pair with DHT11 Temperature & Humidity Sensor Module, AM2302 (DHT22) Temp & Humidity Sensor, HTU21D Temperature & Humidity Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
