We need to define the pin & type of the DHT sensor:
#define DHTPIN 8
#define DHTTYPE DHT11
And create the instances for the DHT sensor & BMP sensor:
DHT
dht
(DHTPIN, DHTTYPE);
Adafruit_BMP085_Unified bmp
=
Adafruit_BMP085_Unified(
10085
);
In the
setup()
function, we can initialize the BMP sensor:
bmp.begin()
In the
loop()
part of the sketch, we make the different measurements:
// Measure the humidity
float
humidity
=
dht.readHumidity();
// Measure light level
int
lightLevel
=
analogRead(A0);
// Measure pressure & temperature from BMP sensor
sensors_event_t
event;
bmp.getEvent(
&
event);
float
pressure
=
event.pressure;
These measurements will then be printed on the Serial monitor.
Note that all the code is available inside the GitHub repository of the topic:
