Dual Outlet CO2 Controller with NDIR Sensor for Grow Room, Automatically Regulates Fans and Displays CO2, Temp, RH

great machine for simply and easily keeping co2 levels safe for people in a smaller sized space, works great.

Product comes as advertised. Great value for the price.

So far I have had 3 co2 monitors and 2 controllers. The co2 detection on all of them is highly questionable and inconsistent. With that said, this controller offers the best features I've seen and seems to be generally approximately accurate. One thing that I like is the programmable hysteresis so it isn't toggling on and off constantly. I would appreciate a feature where it could stop and trip an alarm if its output fails to lead to proper control of (the alleged) co2 value. I grow mushrooms, so if it is blowing air in, it is blowing humidity out. If it thinks the co2 level is too high and keeps running too long it could destroy the shrooms by depriving them of humidity. Overall, it is the least bad controller I have found so far.

This is the missing tool you've been needing for taking your gourmet mushroom growing to the next level. I have a Martha Tent and this fits inside nicely, to monitor CO2 levels very easily. I like now the cord is extra long, incase you don't have an outlet nearby.One issue I've had growing gourmet mushrooms in the past was too much CO2 which was causing my mushrooms to develop long stems. This works to exhaust the CO2 in the tent, when connected to a duct fan. The fan turns on when the CO2 gets too high, and exhausts the air in the Martha Tent outside, through a nearby window. This keeps CO2 right in the sweep spot and Oyster mushrooms love it!My recommendation? Get this! It's a great value!

I totally love that this come with a remote sensor so you can get a CO2 reading where you most need it. I got this for my grow tent which I use for winter growing and cloning / seeding activities. My current CO2 system is pretty rudimentary, and this is exactly what I needed to get a very simple system under control. The quality is excellent, and I also like the ease of use - spin the dials. It also features temp and relative humidity indicators, which is a nice inclusion and something I normally have to have another piece of equipment for. Overall, I'm very happy with this and it's the cornerstone of my new CO2 system upgrade.

Easy to use an accurate CO2 controller for Your grow room. Very accurate and the functionality makes it well worth the money.

I recently purchased this CO2 controller with dual outlets. The price is quite reasonable for the quality and features you get. Setting it up was easy, and it’s very user-friendly. The dual outlets are a fantastic addition, allowing for more flexibility in use. I particularly like the plant and human modes, which cater to different needs effectively.The long cable is very convenient, and the LED screen is easy to read. The inclusion of temperature and humidity displays is a nice touch, providing all the information I need in one place. This CO2 controller is an excellent choice with great features and ease of use. Highly recommended!

This CO2 Controller by DANOPLUS, is a great way to attempt to track the level of CO2 in your grow room with a fairly good level of accuracy. Here are some of the things I’ve learned while owning it and things to consider before buying, including flaws.I. Quality – The overall quality is pretty good, but somewhat generic. Considering that it just sits on the wall with little need to touch it much, the quality should be more than sufficient.II. Performance – It has worked good with fairly accurate readings that have provided a good way to control the level of CO2. None of these seem to be highly accurate and this one is probable the most accurate I’ve tried. It’s been great to have a device that’ll measure the levels and turn on and off two sockets within my set parameters.Overall, this is a solid, fairly bargain choice that has performed well and left me happy to have it on my team. I’ll be sure to update this review, if I ever start to have problems with it.You can trust that this review is simply my honest opinion that is attempting to provide you with helpful insight that I wish I had before I picked this product. Hopefully it was helpful in your decision.
