DHT11 Temperature & Humidity Sensor Module

Integrated Signal Conditioning PCB: Built on a compact breakout board with an onboard pull-up resistor and decoupling capacitor, enabling direct, solderless plug-and-play prototyping.

Calibrated Composite Digital Output: Combines a resistive relative humidity sensing component and an NTC thermistor with an 8-bit microcontroller to deliver pre-calibrated digital signals.

Single-Bus Digital Data Protocol: Communicates using a simplified 1-Wire interface, conserving valuable digital I/O pins on host development boards.

Low Power Consumption & Wide Voltage Support: Operates efficiently between 3.0V and 5.5V DC, ensuring complete compatibility with 3.3V and 5V microcontroller platforms.

Standard 3-Pin Header Interface: Standard 0.1" pitch header pins (VCC, GND, DATA) allow quick connection using Dupont female jumper wires.

Board Material: High-grade FR-4 glass-epoxy breakout PCB with blue sensor housing, soldered 3-pin male header connector, and surface-mount components.

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 Protocol: Single-bus Digital Signal.

Board Color: Blue PCB with Blue Sensor Enclosure.

Usage Advice: Connect VCC, GND, and DATA pins accurately according to pin labels; utilize standard DHT libraries in Arduino IDE, ESPHome, or MicroPython for rapid code development.

Maintenance: Keep the ventilation grid clear of dust and debris, and avoid placing the module in condensing humidity environments or corrosive gas conditions.

Essential Beginner Environmental Module: Position as the definitive starter module for makers, students, and hobbyists building initial temperature and humidity monitoring projects.

Highlight Plug-and-Play Breakout Convenience: Emphasize how the onboard pull-up resistor simplifies circuit setup by eliminating the need to add external discrete resistors on breadboards.

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