Software Code
Open Arduino IDE.
Install the
Grove Temperature and Humidity Sensor(DHT11) library: Navigate to
Sketch -> Include Library -> Manage Libraries… and Search for the keyword “Grove
Temperature and Humidity Sensor(DHT11)” in the Library Manager, then install.
Copy the following code, click Verify to check for syntax errors. Verify that there are no
errors, and you can upload the code.
//Temperature and Humidity Sensor
