+In this part, you should put the keys for Over-The-Air Activation (OTAA) as explained in the LoRaWAN specification:
 <code c++>
 // USE YOUR OWN KEYS!

+The pins for connecting the sensors are specified in these declarations (A0 for light sensor, A2 for moisture sensor, and D0 temperature sensor):
+<code c++>
+int light_pin = A0;
+int moisture_pin = A2;
- a light sensor on pin A0, A2 (moisture sensor), and D0 (temperature sensor).
+int temperature_pin = 0;
-  * OTA join method
+int temperature_vcc_pin = 1;
-  * Frequency channels
+int moisture_vcc_pin = 8;
-  * Message sending
+int moisture_gnd_pin = 7;
+</code>
+The OTAA method is used for joining the network and adaptive data rate is activated:
+<code c++>
+LoRaBee.initOTA(loraSerial, devEUI, appEUI, appKey, true)
+</code>
+Eight different sub channels are activated with data rate ranges from 0 to 5:
+<code c++>
+  LoRaBee.configChFreq(0, 868100000L,0,5,1);
+  LoRaBee.configChFreq(1, 868300000L,0,5,1);
+  LoRaBee.configChFreq(2, 868500000L,0,5,1);
+  LoRaBee.configChFreq(3, 867100000L,0,5,1);
+  LoRaBee.configChFreq(4, 867300000L,0,5,1);
+  LoRaBee.configChFreq(5, 867500000L,0,5,1);
+  LoRaBee.configChFreq(6, 867700000L,0,5,1);
+  LoRaBee.configChFreq(7, 867900000L,0,5,1);
+</code>
+Finally, the message is sent in an unconfirmed upping message:
+<code c++>
+LoRaBee.send(1, (uint8_t*)message.c_str(), message.length())
