What are the best Arduino sensors for beginners?
Some great sensors for beginners include the DHT11 for temperature and humidity, the HC-SR04 for distance measurement, and the MQ-2 for gas detection.
Can you tell me more about the DHT11 sensor?
The DHT11 is a basic, low-cost digital temperature and humidity sensor. It provides reliable readings and is easy to use with Arduino.
How do I connect the HC-SR04 to my Arduino?
To connect the HC-SR04, connect the VCC to 5V, GND to ground, Trig to a digital pin, and Echo to another digital pin on your Arduino.
What projects can I build with these sensors?
You can create a weather station with the DHT11, a distance measuring tool with the HC-SR04, or a gas leak detector with the MQ-2.
