AC InfinityCO2 Controller, Smart Outlet Carbon Dioxide Monitor, Two-Plug System Best Fit with CO2 Regulators and Inline Exhaust Fans, Adjusts CO2 for Grow Tents, Grow Rooms, Greenhouses

Seems well built, should last. I can't verify how accurate it is, but it does seem to respond quickly if I blow in the direction of the sensor. I am using it to keep CO2 low in a room with a reef aquarium. I hooked up a power supply from this sensor to a Konnected Wifi module that integrates into Samsung Smartthings to control some exhaust fans and a powered valve on a CO2 scrubber. Works well. Before hooking this up, CO2 levels were hitting as high as 1,300. Now its down to about 490.Not super intuitive to set up, but not too hard. Take your time and read the instructions, maybe a few times.All in all, very happy with the product.

I like it, I use it in a mushroom tent.

I spent over 300 on different monitors for my veggie room. This one is by far the best one! It's easy to install, very accurate from what I can tell, it's cheaper then all the other wall mounted ones, and it has more then one function! It can act as a timer for a plug, or it can control your co2 tank based on the parameters you set. Highly recommend

it works...but it doesn't connect to their controller, has no ability to remotely manage.

It's a solid unit that's well constructed. You can hear/feel a solenoid click when switched on. Being able to adjust the CO2 to remain off at night is vital. (Plants obviously don't need to photosynthesize at night.)It's a bit tricky getting it set up, the controls can be intimidating to program. Be sure to look at your room size and adjust the tank valve accordingly.The adjustable chart marking the CO2 value of each month, week, day, hour and minute helps with fine-tuning.It takes a while to program, but once it's fine-tuned you can walk away without worries.Consider purchasing a secondary CO2 monitor for outside of any grow space. That way you can tell the difference in room vs grow room levels.Happy growing!

This is the redheaded step child of the AC infinity system. it doesn't work with the system, its the one in the ac infinity family that doesn't belong. yea its good to have if you want to sit in front of it to read the screen all day, but then, what is the purpose if you have to be right there anyway, might as well just manually turn it on.I purchased the cloud lab and was sold on the "system" so I bought the 79 controller and loved the ease of use, realizing the system was as cool as it sounds. when I realized it didn't sense CO2 levels I bought this and though it looks like it is part of the "AC infinity" family. it sleeps in the garage and doesn't get to play with others.what a huge disappointment.

Once you get it set up works great

Product comes as advertised. Great value for the price.
