## What are the functionalities ?
The station is equipped with the following sensors and has these functionalities :
* Temperature (BMP280 and HTU21)
@ -18,7 +17,12 @@ The station is equipped with the following sensors and has these functionalities
* Sunlight (LDR)
* Battery level indication (ATMEGA's 10 bit ADC)
## Project folder architecture
## Power consumption :
* Around **60µA** during sleep
* Around a **13mA** spike during data transmission and **4mA** during sensor data collection.
* The solar panel is enough to charge the battery it should thus never need to be replaced or recharged.

## Getting started :
1. Clone this repository : git clone http://web-directories.cf/git/Th3maz1ng/ATMEGA328PU_lowPower_weather_station.git
2. Go to src/libs and copy and paste the content in your "Arduino\libraries"
3. Select the "Arduino Pro or Pro Mini" board with processor : (Atmega 3.3V 8 Mhz)
4. Compile and Upload !
5. To receive the data emitted by the station, you can check this other [project](http://www.web-directories.cf/git/Th3maz1ng/ESP8266_dual_NRF24l01_gateway).
## Configuration options :
You may change some settings present in the ***definition.h*** file.
Set **SLEEP_4_SEC_INTERVAL** which corresponds to the time interval between each data transmission in 4 seconds increments. 1 minute by default corresponds to a value of 15.
Set **SERIAL_DEBUG_ENABLED** to **1** to get debug output on the serial console.
Set **SERIAL_BAUD_RATE** to the desired baudrate for debugging.
Set **ADC_QUANTUM** to adjust the quantum if your VREF is not the same as mine.
To do so, measure which voltage does the VCC pin of your Arduino board output and divide it by 1024 (10 bit ADC resolution).
Set **VOLTAGE_DIV_COEFF** to something different if you changed the voltage divider resistor values.
Set **RADIO_CHANNEL** to the NRF's RF channel (between 0 and 124). **Do not forget to set the receiver station up accordingly**
Set **RADIO_NODE_ADDRESS** to change it's 5 byte address if you feel like it.
Set **RADIO_PA_LEVEL** to adjust the transmit power level if needed (higher power, higher current consumption)
## The hardware :
Here is a list of the parts used to build the station with a link to the page of each products :
