🪴 Plant 🪴

This is a project to keep my plants from dying! It uses a range of sensors to water and light the plant at an ideal time. It also monitors some environmental factors and uses a fan to remove more CO2 and VOCs from the air. All of these are then made available on a web dashboard. It deactivates during the night so you can have it in a bedroom without the lights or motors waking you up.

Monitors

• 💧 Soil Moisture (used to water plant)
• ☀️ Light (used to turn on glow lights)
• 🌡️ Air Temperature
• ☁️ Air Quailty (CO2 and VOC)
• 💦 Air Humidity

📈 Dashboard

✔️ Prerequisite

📚 Install Libraries

Install the platform IO libraries:

🏃 Run

add embedded/keys.h with this content:

#define SSID ""  // WiFi SSID
#define PASSWORD ""  // WiFi Password
#define REFERENCE_URL "" // Firebase realtime database reference URL

Make sure the ESP32 has Arduino firmware flashed. Verify the code compiles then upload it to the ESP32
