These are some questions that were asked of me, regarding the GrowGreen LED Controller. I thought I would answer them here instea so many understand the same.
questions are anonymous:
So my questions for you based on my personal needs and short comings of the competition
1.-can I control my 0-5v & 0-10v simultaneously
2. -can I control my far reds for 10mins after lights off
3. -can I control my 12 hour photo period of my flower & 18 hr veg photo period
4. -are there other options available now, or in the future for temperature probes
5. -can you elaborate on the relay. Everyone always scratches their head when their HLGs only dim to 10%, are you saying there is an included ac/dc ssr that will shut AC power to my HLGs. if this is the case, is there an option for multiple ac/dc relays.
1. yes. the cable i show delivers both 5v and 10v pwm signals for all eight channel.
2. Yes. The Controller works with LDD Controller boards, rapidleds and corulax, and power supplies and mean well LDD drivers .
3. Yes. The Controller has the ability to independently control the photo period for all eight channels simultaneously performing both veg and flower I have been using it for that for some time now..
4. An existing temperature sensor is included as part of the Real Time Clock circuit, which will give ambient room temperatures but not a temperature probe. I leave temperature sensing and controls to other existing environmental sensors on the market. I do not see the temperature probe a necessity for lighting controls, but more for CO2 and AC controls, environmental to me.
5. Regarding the opto-isolated relay. The relay delivers or cuts power to the Li9ne circuit of the AC side. The Line circuit is interrupted by the PWM signal, either inhibit or prohibit. The relay only has to see the current from a single driver, not multiple drivers. Each relay is used to control each driver. if you have two drivers you need two relays. You do not need two PWM channels to control two relays, just one pwm signal for the both if you want both drivers to behave identically. Each relay never pulls more than the driver demands. mean well recommends no more than six drivers on a 15 amp circuit. That has no impact on the relay. The relay is inline with the current flow of the individual driver. The cable I manufacture provides both a 5v pwm signal for the relay and a 10v pwm signal for the driver dimming. Both are generated from a single arduino pin out. You can control up to 16 relays with 8 pwm signals from terh arduino without any problems. After 16 relays you need a second controller or else get with me to design a larger version that can handle more channels. I have the option to code for many channels. I also have the capability to add more pwm channels by adding additional pwm cards that add 16 chanels at a time. Additional coding is required and can be accomplished, but I have to do the coding for that purpose. if there is a demand for higher channel units I will approach the issue. Until then I am going with the 8 channel model. If you want 24 or more channels you are going to have to hit me up and we are going to have to talk aboput how to get there. An Arduino mega 2560 is the first step, and that cost $49 up from $25 for the Arduino alone plus parts and time. Negotiable.
Future plans, a wifi version and a blue tooth version are both in the works, along with an internet capable version. peace
