eAgrar - digital agriculture

Hi,

just to take you up to date.
We improved our design and made it fully modular so every part can be easily changed. 

Also, we improved our power consumption so it can be powered with 1 D size battery for 10 years with sending 100 messages per day.

I added enclosure for temperature and humidity sensor. It is important to protect it from direct sunlight and rain.

I took this 3D model from Thingverse and resize it a bit.  Here is link and thanks author for great work!

Here is link on basic code for sending messages to The Things Network gateway. Data which you are sending are measured with BME280 sensor (temp/hum/pressure). 
Code is based on LMIC library (LoRa MAC in C) and on LowPower library.

Code is made by Lex Bolkesteijn (github account: ph2lb).

Here you can see schematics of sensor device.

On this picture you can see how looked like our version 1 device. It was consisted of modules which were connected together with one PCB. On that way we were able to test modules really fast. But to spare size of box, and make it more robust, we transfered everything on board.

Also, now we added waterproof connectors so our new device is able to take all atmospheric conditions.
