LED matrix display ALLNET ALL-4duino-8x8 with integrated temperature and humidity sensor

The ALLNET ALL-4duino-8x8 LED matrix display is a compact, addressable 8x8 module that combines a pixel matrix with an integrated temperature and humidity sensor. This module is intended for simple visual indicators, small animations, and simultaneous environmental monitoring in DIY, prototyping and educational projects. Its small footprint makes it suitable for embedding in maker devices, control panels and desktop prototypes where both visual feedback and ambient data are useful.

Advantages

The integrated design brings together an 8x8 LED matrix and a humidity/temperature sensor in a single module, reducing wiring and simplifying assembly. Addressable LEDs allow precise control of individual pixels for text, icons or basic animations. The compact size and low power consumption support battery- or USB-powered applications, while the combination of visual output and sensor readings enables immediate on-device feedback without additional external sensors.

Suitable for

• DIY electronics and maker projects requiring visual indicators and environment sensing
• Prototyping small user interfaces or status displays
• Educational projects teaching LEDs, matrices and sensor integration
• Desk displays for ambient temperature and humidity readouts
• Wearables or small installations where compact visual feedback is needed

Key specifications

• Display type: addressable 8 x 8 LED matrix
• Integrated sensor: temperature and relative humidity measurement
• Control interface: standard microcontroller-compatible signal lines for matrix control
• Power: low-voltage operation suitable for USB or battery supply
• Mounting: compact module size for integration into enclosures or breadboards
• Typical uses: icons, characters, simple animations and ambient condition indicators

How to use

Connect the module to a compatible microcontroller or development board following the required power and data connections for the LED matrix and the sensor. Install or write firmware that addresses individual LEDs for images or animations and queries the temperature/humidity sensor at intervals. Use simple mapping for the 8x8 grid to display icons, scrolling text or visual representations of sensor values. Test power supply stability and ensure the sensor is placed where it can measure ambient conditions without heat sources nearby that could bias readings.

Recommendations

Place the module away from direct heat sources and enclosures that restrict airflow to ensure accurate temperature and humidity readings. For longer animations or higher brightness, verify the power source can supply the peak current. When integrating into projects, combine sensor readings with simple visual indicators (e.g., numeric values, bars or color changes) for quick interpretation.
