Week 9 - Input Devices

This Week i used the read data from the DHT22 Temperature and Humidity with the Board i designed in week 6 and produced in Week 8. I programmed the board with the Arduino IDE.

In our group assignment, We showed, how . Due to the fact, that i was overseas for a Conference I was just Responsible for The Website. So Crossreading, the Content and also Adding it to the Site and Pushing everything to our Internal Git.

Prepwork

board setup

First i have to setted up the Pi Pico 2 W as Borad. For that i used the RP2040 BoardLibrary from "Earle F. Philhower, III". Step 1 was to open the preferences and add "https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json" to "Additional boards manager URLs"

Second steo was to install the Boards in the Boards Manager.

libraries

The Library used in this sketch is the "DHT sensor library" by Adafruit. U can download it through the library manager

connnecting the and sensor

To Connect our Sensor, use the second GP-Pin, which is "DHT-DATA" and the power pins on our board (marked with "DHT-VCC" and DHT-GND). Every pin used for the DHT is colored Green.

                #include 


                #define DHTPIN 1
                #define DHTTYPE DHT22
                
                float temp;
                float humidity;
                DHT dht(DHTPIN, DHTTYPE); 
                
                
                void setup() {
                  Serial.begin(115200);
                  dht.begin();
                }
                
                void loop() {
                  temp = dht.readTemperature();
                  humidity = dht.readHumidity();
                  
                  Serial.print("Temperatur: ");
                  Serial.print(temp);
                  Serial.println(" *C");
                  Serial.print("Luftfeuchtigkeit: ");
                  Serial.print(humidity);
                  Serial.println(" %");
                
                  Serial.println();
                  delay(2000);
                }
