SolarSens - 3D printable solar weatherstation

A 3D printable modular wifi weatherstation.

Similar projects worth following

SolarSens is a modular weather station.

It can be equipped with various sensors. Sensors, which also have to be illuminated by sunlight, can be installed waterproof on the "sensor phalanx" above the solar cell on the outside. This way brightness and UV exposure can also be measured.

Additional sensors can be installed inside the weather station (for example temperature and humidity sensors). In addition, an SDS011 can be "piggybacked" on the back of the housing.   The solar cell on the front supplies the electronics with energy and charges the built-in 18650 LiPo cell.

The measured data can be sent to your own SmartHome using WiFi.

I am currently working on a new circuit board, which should enable the data to be forwarded via LoRa and / or gsm.

  • Finished CAD work (mostly)

    At the moment I'm still working on the final parts of the design. You can see the current status in the pictures.

    What is still missing are the modular sensor housings, which are screwed onto the front panel below the solar cell.

    Compared to the first version, I have positioned it under the solar cell. The idea behind it was that the sensor housing would not be able to cast shadows on the solar cell and that in the event of a leak, the moisture could not penetrate the upper edge but only very far down into the housing.

    On the rendered views you can already see the stepper motor in the base with which the housing should always align itself towards the sun. A suitable stand on which the weather station can be rotated is missing here. :)

  • First version of the sensorPhalanx PCB

    In the last few weeks I have worked a little on the first version of the solarPhalanx PCB.

    This PCB contains all kind of light related sensors, with which the brightness, radiation values and even the alignment of the weather station can be determined. 

    Unfortunately, due to the current shortage of chips, not all sensors are available.  But there are definitely enough left for a first test. :)

    A first overview of the available components can be seen in the picture below.

  • First version of the solarSens MCU PCB

    Fab10/26/2021 at 18:27 0 comments

    In my last project log I posted some initial information about the sensorPhalanx PCB. I want to use this PCB with numerous light sensors as one of the environment sensors for my solar powered weather station solarSens.

    Of course, I also need a suitable MCU to evaluate and distribute the measured data. This (ESP32) is placed on the solarSens PCB shown. 

    In addition to the MCU, there are numerous other components installed on it. These include a GSM or LoRa radio module, a solar MPPT charger, a possibility to use the connected solar cell as a pyranometer, a stepper motor driver for the correct alignment of the solar cell and many other features. 

    You can get a first rough overview on the pictures shown. :)
