Day and Night CO2 Monitor and Controller for Greenhouses

Day and Night CO2 Monitor and Controller for Greenhouses

The Day/Night CO2 Monitor and Controller for Greenhouses is a device that controls the levels of CO2 in your greenhouse during the day. With the advanced hysteresis logic, this device lets you set low and high target CO2 levels, and then provides power to the CO2 generator through a built-in 100-240 VAC 5A piggyback cord. Once you reach your target level, the device automatically shuts off power.

Features of day night co2 monitor and controller for greenhouses

The most popular brand of day and night CO2 monitor and controller for greenhouses is Titan Controls' Atlas 3 model. It works between 0-2,000 PPM and is compatible with Titan CO2 devices, such as regulator kits and tank and regulator kits. It's also super-efficient, requiring only 5 amps of power and 120V AC. Choosing a brand you're comfortable with is a good way to make sure the product is right for you.

The Titan Controls Atlas 3 Day/Night CO2 Monitor/Controller allows you to control CO2 from zero to 2,000 PPM and offers features for enrichment and exhaust. Its weather-resistant enclosure resists rust and moisture. Whether you're growing vegetables, berries, or any other type of plant, this controller will be the perfect companion for your greenhouse. With this device, you can have complete control over the CO2 levels in your greenhouse.

The CO2Meter has a built-in photosensor to detect light. When it's dark, plants cannot perform photosynthesis, and supplying CO2 at night will deplete the tank and waste energy. When using supplemental light, the CO2Meter turns off the regulator. It also has six stand-alone programs. Different periods require different amounts of CO2, which means you need to set different CO2 ppm levels during each time.

Some models have built-in memory for 7 days, which makes them useful for analysis purposes. You can use this data to resolve any yield problems. They can display up to 17 previous readings and the CO2 set point and permissible zone. The CO2 monitor does not read the current temperature. It is essential to check the CO2 level in the greenhouse regularly. Using supplementary light and increasing the temperature can extend the growing season and improve yields.

Installation process

CO2 Monitor & Controller for Greenhouses - How to install a greenhouse CO2 meter? Installing the CO2 Meter & Controller is not difficult - the package includes all necessary hardware and cables. Connect the CO2 generator or regulator to the controller's jack. Place the unit outdoors and warm it up for three minutes. Press and hold the "Calculate" button for six seconds to calibrate the unit. It will automatically turn on the regulator when the CO2 level falls below the set point, and will shut down the device when the CO2 level rises above the permissible zone.

The CO2 monitor and controller for greenhouses measures CO2, humidity, temperature, and lighting spectral. With up to 15,000 stored data logs, the Extech CO2 Monitor is capable of monitoring and controlling CO2 levels in any greenhouse. Because CO2 diffuses slowly, proper air circulation is essential to evenly distribute the gas throughout the greenhouse. Air flow is critical to evenly distribute CO2. Single generators and small connected greenhouses use a horizontal air flow fan to move CO2 from the air to the plants. Large connected greenhouses use plastic tubes perforated at various intervals. These tubes are placed at or below the crop level and under the bench to supply adequate CO2 to the leaf boundary layer in dense canopy conditions.

A greenhouse with a gutter of 2.4 m will have an air volume of 400 m3/100 m2. Therefore, in order to enrich the CO2 level in a greenhouse, 1,000 ppm or 0.1% of CO2 is required. This CO2 can be added before sunrise to maximize photosynthetic activity, while reducing carbon dioxide levels by natural air exchange and photosynthesis.

CO2 levels are usually lower during the day than during nighttime, which is why installing a Day-Night CO2 Monitor and Controller is recommended. CO2 levels are more difficult to maintain in a greenhouse during warmer days, and night-time CO2 levels are the most critical. By using a Day-Night CO2 Monitor and Controller for Greenhouses, you'll be able to keep your greenhouse plants healthy and happy throughout the day, and cut down your energy costs significantly.


A Day/Night CO2 Monitor and Controller for greenhouses allows growers to easily set the desired CO2 level. It supplies power to a CO2 generator or regulator and has a built-in photo sensor for easy fresh air calibration. Day/Night CO2 controllers are ideal for greenhouses, grow rooms, hydroponics systems, and other spaces. Read on to learn more about their benefits and the cost of buying them.

This day and night CO2 monitor and controller provides a 7-day history and features CO2 enrichment and exhaust. The unit is protected from moisture and rust with a durable enclosure. Moreover, these monitors record CO2 levels in greenhouses for up to 7 days. In addition, they have a built-in memory for 17 previous readings. Despite the built-in memory, day/night CO2 monitors and controllers do not provide current temperature.

The cost of a day/night CO2 monitor and controller for greenhouses will depend on how much you plan to use it. The average unit costs approximately $350, and you can choose between a manual or automatic controller. The CO2 level controller can be set to one or two pre-defined levels. It can detect when the CO2 level is low or high and shut off the regulator when it reaches its desired level.

The cost of day/night CO2 monitor and controller for greenhouses is relatively low compared to the price of continuous CO2 control. The day/night CO2 controller uses less electricity and water while providing similar results. The results can be slightly better or similar depending on cultivar and species. The cost of day/night CO2 control can be lower than the cost of continuous CO2 control for specific crops.

Visual characteristics

A CO2 Monitor & Controller is easy to install. It comes with all necessary cables and hardware. To calibrate the sensor, you should pump air samples from different greenhouse sections to a cooler or colder CO2 sensor outside the greenhouse. Make sure to hold the calibration button for six seconds and then wait 20 minutes. After that, you can use the CO2 Monitor & Controller to set the CO2 levels for your plants.

The supplementary lighting system was powered by high-pressure sodium lamps, capable of producing 200 umol m-2 s-1 of PAR. It was located at a height of 1.75 m below the luminaires and turned on when sunlight radiation flux was less than 300 umol m-2 s-1 at bench level. The controller had a fifteen-minute control delay to avoid excessive cycling of the supplementary lighting system.

The visual characteristics of a day night co2 monitor and controller for greenhouse plants should be consistent. The eave height and canopy volume can affect the uniformity of greenhouse air temperature. This can be improved with the use of an air distribution system. The visual characteristics of day night CO2 monitor and controller for greenhouses should be the same as in the case of a temperature control system. In this case, a sensor should be calibrated once every year.

In addition to its visual features, a Day/Night CO2 monitor and controller for greenhouses also has sensors for detecting CO2. They should have a built-in light sensor, a piggy black plug, and a plastic enclosure. Zephyr 1 Day/Night Temperature Controller has day/night controls, a 6-ft temperature probe, and a plastic enclosure.
