Standalone esp8266 server built to control the lighting time in aquariums, where the light intensity and duration is critical for a healthy plant growth.
The served dashboard, based on Materialize CSS, plain JS and Jquery, is used to display a light_intensity over time graph and to adjust the parameters.
Light curve is based on a gaussian function parametrized by three variables:
- Time: Time range when the light should be turned on and of
- Power: The maximum ouput power ever used by the controler
- Floor: The power the light should be when it turns on/of. Also controls how smooth the curve gets
The time is automatically mantained via a ntp server and the configs are saved on flash every time you hit the STORE button.
The only harwdare you need is:
- 1 esp8266
- 1 DS3231 RTC
The output is up to you to hook up to whatever you need. The PWM pins related to the color data shown on the web server is configured through these two assignments:
//main.cpp
//In this case, D5 is mapped to "ww" and D6 to "cw"
int color_pins[color_number] = {D5, D6};
char color_names[color_number][3] = {"ww", "cw"};
In my case, I used one logic level N-Channel mosfet to drive a 12v LED strip for each channel, getting a connection diagram like this
If you don't want to use the web interface, or want to have the hability to also control via something else, you can use the TCP direct mode.
Send a simple TCP packet containing a 32bit number from 0 to 1024 for each of the light values in the order assigned to the color_names/color_pins arrays.
You can set the timeout of this direct command through the MANUAL_TIMEOUT definition
Now you can just enjoy your time without having to worry about the photoperiod of your plants:
