Arduino project: Control and Logger for Aeroponics Grow Cabinet

This unit will control my Micro-Aeroponics-Grow-Cabinet (w. Bubble Bucket)

• Arduino Uno (or Mega) with shields and sensor connecting board
• Ethernet Shield connected to Blynk (iPhone App);
  (create dashboard for monitoring sensors and switching two relays: (1. Timer for Lamp;  2. Thermostat for Heater).
• Datalogger Shield with SD-card and Real Time Clock (for timestamp);
  Logger via Ethernet (future WiFi) to Xively channel and visualizing in graphs by Github.
• External power supply for sensors en relays.
• Casing for Arduino board and shields, water resistant with clear cover;
  In/out: DC-9V, Ethernet-Cat5, DS18B20-RJ11, DHT22-RJ11, Relays-RJ11, optional: USB to iMac.
• Casing for Relay/Power Outlet;
  In/out: AC230V, RJ11 (4 wire) to Arduino board.

Sensors:

1. Barometer (Pressure/Temp sensor BM-180).
2. Temperature and Humidity at the top of the plant (DHT22).
3. Luxmeter (Illuminance sensor BH1750).
4. Timer relay control lamp (Blynk dashboard).
5. Thermostat relay control heater in the water container (waterproof Temp. sensor DS18B20).
6. Waterlevel: distance w. Ultrasonic sensor module by independent Nano.
7. pH-sensor by independent Uno (w. Bluetooth Bridge).
8. EC-sensor (future extension pH-board with EC/TDS sensor (conductivity).

2-relay module in mini casing: switches Timer-relay and Thermostat-relay

beta version in a test tray, the final casing is in order.

a larger version as the relay-casing

for Arduino Mega and connection parts
