Project Tomato

My project to make an automatic tomato waterer with a JSON-API and Wifi-Support.

Used hardware

All links are examples, similar devices should work, too.

• ESP8266 with at least 3 GPIO-Ports available (in my case I'm using GPIO4, GPIO5 and GPIO14) Link
• 2 I2C capacitive soil moisture sensors Link
• Electric Solenoid Valve Link
• 12V Relay
• Drip hose (with fitting pressure reducer)
• Water hose, adapters, ...

Used software/libraries

• Arduino SDK 1.6.8 (or other current versions)
• ESP8266 hardware library (via Arduino SDK board manager)
• ArduinoJson Link
• Modified version of I2C Soil Moisture Sensor library Link
