The DHT11, 21 and 22 Sensors can be used to determine both temperature and humdity. Note: Make sure to comment/ uncomment the right sensor in setup Links: Adafruit DHT Library – https://github.com/adafruit/DHT-sensor-library Functional Parts in […]
PIR Sensors (Passive Infrared) are the standard sensors used for motion detection. They offer a wide field of view and are easy to configure, but offer only HIGH/LOW output and are not overly accurate. Functional […]
Photoresistors are analog sensors that allow your Arduino to determine the level of light in an environment. Note: You can use either 5 or 3.3 volt power for this project, and you can use different […]
Analog Soil Moisture Sensors allow you to determine how dry soil is and then trigger an event such an LED turning , or a water pump being turned on. Note: Give the sensor a few […]
You can use Analog Pins on your Arduino Board to read from an IR sensor if you need a numeric reading. Functional Parts in the Project: Arduino Uno – https://store.arduino.cc/usa/arduino-uno-rev3 IR Sensor – https://amzn.to/2IDw7SE
IR sensors can be used for obstacle avoidance on Arduino vehicles. Using the digital output option you can code based on a simple true false statement rather than testing against a range. Functional Parts in […]
