The Fish program is from here on to be known as “Waterchippy”. This is mainly due to the fact that the application no longer features a fish theme. Instead it will camouflage itself as a fake flying toasters screensaver. It even blocks alt-tabbing and windows/alt keys.
Fish, sorry: Waterchippy, is now showing the same graphs as the web based interface.
Yellow line: Light
Red line: Temperature
Blue line: Water level
Light blue line (not visible in pictures): Humidity
Green line: Ph
Most functions seems to be working now. There is now also some support for the farenheit scale. Today I also added a smoke sensor, mostly out of boredom. I figure it might be nice for a grower to know that the garden is not on fire, for the moment.
Work has also started on the “Fish” program. The program (Windows only) will monitor/control the Waterchip and alert whenever there are any problems.
The Waterchip has now been running without a reset for 48 hours! As it turns out it was a faulty channel on a relay board that caused the problem. The kickback simply caused a power ripple that reset the device.
The last “24 hour” ph report:
Waterchip sporting a humidity/temperature sensor, an LCD, a micro-sd card and an ethernet port.
On reset the LCD shows the set ip adress. The same adress is also sent over serial if no LCD is available.
Waterchip 1.0 is a one man project aimed to automation of hydroponics systems. using the Arduino MEGA platform. When finished the system will:
- Read temperature and humidity
- Read and adjust ph up and down
- Read water (float switch and sonar) and add water to a reservoir when needed
- Detect light on/off (in case of faulty timers)
- Log ph, temperature and humidity to micro sd-card
- Serve a web page with control functions, last 24 hrs graphs and so on
- Support export to a real time full screen control program
- Show data on an optional lcd-screen
