SOLAR POWERED WIFI WEATHER STATION V2

thingiverse

Here's an overview of my project: This is a basic build, and you can find more information about it here: https://www.instructables.com/id/Solar-Powered-WiFi-Weather-Station/. The wire diagram is courtesy of an Austrian contributor. I've created new housing and rewritten parts of the code. Here's how it works with the Blynk app: 1x Wemos D1 mini PRO (https://de.aliexpress.com/item/1PCS-D1-mini-Pro-16M-bytes-external-antenna-connector-ESP8266-WIFI/32803725174.html?spm=a2g0s.9042311.0.0.30024c4dou9RgR) To set up: * Bridge RST and D0 for Deep Sleep * Add a 200k Ohm resistor between A0 and 5V for battery voltage measurement * Bridge the external antenna resistor (as shown in the picture) You can download the Arduino Ino file here. You'll need to create a key on the Blynk app and enter your Wi-Fi data. Components: 1x TP4056 Power Board (https://de.aliexpress.com/item/1PCS-5V-1A-Micro-USB-18650-Lithium-Battery-Charging-Board-Charger-Module-Protection-Dual-Functions-TP4056/32500002822.html?spm=a2g0s.9042311.0.0.37ba4c4dONftzI) 1x BME280 Sensor (https://de.aliexpress.com/item/3In1-BME280-GY-BME280-Digital-Sensor-SPI-I2C-Feuchtigkeit-Temperatur-und-Luftdruck-Sensor-Modul-1-8/32847825408.html) 1x 18650 single holder (https://de.aliexpress.com/item/High-Quality-18650-Battery-Box-Holder-Batteries-Case-for-4pcs-18650-in-Parallel-3-7V-Pole/32814062027.html) 2x Solar Panels (https://de.aliexpress.com/item/Solar-Panel-5V-6V-12V-Mini-Solar-System-DIY-For-Battery-Cell-Phone-Chargers-Portable-Solar/32823762479.html) 2x Shottky Diodes (https://de.aliexpress.com/item/50Pcs-1N5819-5819-1A-40V-SCHOTTKY-DIODE-NEW/32216810320.html) You'll also need some wires, solder, and other materials. To get started with the Blynk app: * Load it up and scan the QR code to access the project * Change the language as needed Print the housing using PETG material. Have fun!
