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.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensor Types\u003c\/td\u003e\n\u003ctd\u003eDHT11 (digital temp\/humidity), LM35 (analog temp), photoresistor, IR receiver, buzzer, button, LED, rotary potentiometer, RGB LED\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V–5.5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTemperature Range (DHT11)\u003c\/td\u003e\n\u003ctd\u003e0°C to 50°C (±2°C accuracy)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHumidity Range (DHT11)\u003c\/td\u003e\n\u003ctd\u003e20% to 90% RH (±5% accuracy)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTemperature Range (LM35)\u003c\/td\u003e\n\u003ctd\u003e-55°C to 150°C (10mV\/°C linear output)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBoard Dimensions\u003c\/td\u003e\n\u003ctd\u003e65mm x 30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-animated-weather-station-display\"\u003eIndoor weather station with real-time display\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/smart-temperature-controlled-fan-with-arduino-kit\"\u003eTemperature-controlled fan or cooling system\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-greenhouse-climate-monitor-kit-with-arduino-uno-plus-sensors\"\u003eGreenhouse climate monitor with data logging\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eSmart home temperature alert via IoT\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks 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.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eSupply 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
