Don’t waste your time buying any other one I did and it was a waste. It’s very accurate and easy to use I highly recommend. Review: Solid controller - I am pleased with this controller. I own a mushroom growing operation and recently gave this controller a shot because my old one finally kicked the bucket. I like the options and easy readout of this one. It was easy to program and calibrate. It took about 20min to setup all my preferences and then it was back to work. I have had it several months now and I recalibrated last week once and it had only swayed 18ppm that is good enough for government work as they say. The price was on point and I will be buying two more for our next expansion. ## Features - 【CO2 Controller】This CO2 Controller is equipped with wide LCD screen, 0-5000 ppm measuing range, it's able to record trend chart of CO2 levels per minute/hour/day/week for analysis - 【Plant Mode&Human Mode】The Carbon Dioxide Controller is designed with Plant Mode and Human Mode, can mannually control the CO2 level for CO2 generator in Grow room, or control the ventilation system indoor - 【Auible Alarm】This CO2 Controller will alarm via buzzer when the CO2 level exceed the setting threshold, and you may manually adjust the CO2 ppm threshold accoringly - 【AUTO Day&Night Detection】CO2 Controllers has auto day and night detection, it will automatically turn off CO2 generator/regulator by turning off the output power during the night - 【Multi-Functional】Wall mounted CO2 Monitor & Controller comes with piggyback socket, Altitude Adjustable from 50 to 500 meters, 14.8 feet (4.5 m) Cable for CO2 sensor ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08H8H9D2M | | Alarm | Audible | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #65,490 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #115 in Indoor Air Quality Meters | | Brand | DANOPLUS | | Color | CO2 Controller | | Customer Reviews | 4.2 4.2 out of 5 stars (143) | | Date First Available | September 2, 2020 | | Included Components | CO2 Controller, CO2 Sensor, screws and tapes and English Instruction Manual | | Item Package Quantity | 1 | | Item Weight | 12.8 ounces | | Item model number | KB0297 | | Manufacturer | DANOPLUS | | Number of Items | 1 | | Operating Humidity | 95 percent | | Part Number | KB0297 | | Power Source | AC100~240VAC | | Product Dimensions | 19.69"D x 6.22"W x 4.17"H | | Sensor Type | Non Dispersive Infrared | | Style | CO2 Controller | | UPC | 619317590304 | ## Product Details - **Alarm:** Audible - **Brand:** DANOPLUS - **Color:** CO2 Controller - **Item Weight:** 0.8 Pounds - **Number of Items:** 1 - **Operating Humidity:** 95 percent - **Power Source:** AC100~240VAC - **Product Dimensions:** 19.69"D x 6.22"W x 4.17"H - **Sensor Type:** Non Dispersive Infrared - **Style:** CO2 Controller ## Images ![CO2 Controller, 0-5000PPM Carbon Dioxide Controller with Human/Plant Mode, 15ft NDIR Probe, LCD Trend Display, Audible Alarm, Day&Night Relay, CO2 Monitor for Greenhouse, Grow Rooms - Image 1](https://m.media-amazon.com/images/I/71qeiqMMg4L.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Everything seems fine but when exceed the co2 level, the fan connected wont turn on.

Good as the more expensive competitors *by M***K on June 21, 2022* This controller works like a charm. Absolutely accurate and it couldn't be easier to set up. Numbers are large so you can see them and the co2 remote detector has a green light so it doesn't disturb light cycle of plants. $100 less than the leading brand and works just as well! ## Frequently Bought Together - CO2 Controller Carbon Dioxide Controller CO2 Meter Monitor Day and Night Relay Function, NDIR CO2 Sensor for Green House, Grow Rooms, Factory, Home, Office - EDYCARX 25ft 1/4" CO2 Drilled Tubing, Black PU, Grow Room CO2 Injection System, Kit Includes Tubing, Fittings & Accessories, Compatible with CO2 Regulator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nl/products/254713094-co2-controller-0-5000ppm-carbon-dioxide-controller-with-human-plant](https://www.desertcart.nl/products/254713094-co2-controller-0-5000ppm-carbon-dioxide-controller-with-human-plant) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-07-10*
