9-in-1 Multi-Function Sensor Board DHT11 LM35 Temperature Sensor
9-in-1 Multi-Function Expansion Board with DHT11 and LM35 Temperature Sensor
This all-in-one sensor board combines a DHT11 digital temperature and humidity sensor with a precision LM35 analog temperature sensor, along with seven additional input/output components. Designed for rapid prototyping, it provides immediate environmental data for microcontroller projects without individual sensor wiring. The board simplifies development of weather monitors, climate controllers, and data loggers.

Compatibility
Works directly with Arduino Uno, Mega, and Nano boards, as well as Raspberry Pi (with appropriate voltage level conversion if needed). The DHT11 uses a single digital pin, while the LM35 outputs analog voltage. All other onboard components operate at standard 3.3V/5V logic, making them accessible via jumper wires or direct header stacking.
Wiring Notes
Supply 5V to the VCC pin and connect GND to ground. For DHT11, connect the DATA pin to any digital I/O (e.g., D2). For LM35, connect the OUT pin to an analog input (e.g., A0). A 4.7kΩ pull‑up resistor is often included on the board for the DHT11; verify before applying external power. Current draw is minimal, but avoid placing near heat sources for accurate readings.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, it connects directly to Arduino Uno using female‑to‑female jumper wires or by stacking on a breadboard. All pins are labeled for easy hookup.
How accurate are the temperature readings?
The DHT11 provides ±2°C accuracy, while the LM35 offers ±0.5°C when properly calibrated. For higher precision, use the LM35 output and compensate in software.
Does this board require soldering?
No soldering is needed; all components are pre‑soldered. Use standard DuPont jumper wires to connect to your microcontroller.
