Weather & plant monitoring station

After some modifications, the project is online again. The main problems with the project was the cheap modules from ebay failed miserably on long run. When the soil sensorts started rusting after one month, they became instable. The buck converter and a BMP280 sensor died. Fortunetly, the email warnings worked and i was able to save the ESP and the PRO mini.

The version 2 is on the way, with properly designed PCB and mutch more reliable modules.

The core problem with this project is the low budget, the chinese parts keeps failing. 3 soil sensors rusted out in a month, 2 buck converters failed and ruined the lead-acid battery. The solar charge controller never worked. The setup originally used 20mA on average, but after the parts started failing, it went up to 100mA. Im planning on using wall supply. After finishing the new case design, i will restart the project.

On the good side, the tomatoes are growing well.
