ESP-Hydropony Light Monitor

Wi-Fi Lux Sensor for Hydroponic & Indoor Growing

A professional-grade light monitoring firmware + PCB design package for hydroponics, indoor farming, and controlled-environment agriculture.

This product allows you to build your own Wi-Fi light sensor, display readings locally on a TFT screen, and query real-time lux values remotely via HTTP.

Designed for reliability, simplicity, and long-term use.

🔍 What this device does

• Measures ambient light intensity (lux) using a BH1750 digital sensor
• Displays the value in very large, high-contrast numbers on a TFT screen
• Connects to your Wi-Fi network automatically
• Provides a built-in HTTP API for remote monitoring
• Runs autonomously once powered (no cloud, no subscription)

Perfect for:

• Hydroponic systems
• Indoor gardens
• LED grow room validation
• Greenhouses
• DIY automation & monitoring setups

🌐 HTTP API (Local Network)

Once connected to Wi-Fi, the device exposes a simple HTTP interface:

• / → device status
• /lux → current light level (plain text)
• /json → light value in JSON format

Ideal for:

• Home Assistant
• Node-RED
• Custom dashboards
• Data logging
• Automation scripts

🛠️ Hardware Requirements

• ESP32-C6 development board
• BH1750 light sensor (I²C)
