About This
- 【High Accuracy Measurement】Accuracy is important for maintaining optimal CO2 levels in indoor growing environments. This CO2 controller indicates that at a CO2 level of 0~3000 parts per million (ppm), the accuracy of the readings will be +/-50 ppm or +/-5% of the reading, whichever is greater. For CO2 levels over 3000 ppm, the accuracy of the readings will be +/-7%. This means that the CO2 controller will provide readings that are accurate within the specified range.
- 【Measurement Range】The device is able to measure CO2 levels ranging from 0 to 5000 parts per million (ppm) with a display resolution of 1ppm for levels between 0-1000 ppm, 5ppm for levels between 1000-2000 ppm, and 10ppm for levels over 2000 ppm.
- 【[Split-type Remote Sensor】The remote sensor comes with a 181 inches long cable making it more convenient to use for monitoring conditions in large or inaccessible environments, such as in industrial facilities or large greenhouses. With its DUAL BEAM feature, you can be assured of improved accuracy and stability of CO2 readings.
- 【User-Friendly Display】The monitor has a clear and easy-to-read display that shows current CO2 levels, a CO2 chart with variable time zoom levels, CO2 center, and zone value, and also the CO2 Max/Min reading. This information can help users better understand the CO2 levels in their environment and make informed decisions about adjusting conditions to maintain optimal levels of CO2 needs.
- 【Versatile Device】Having both Greenhouse and Ventilation modes in this CO2 controller offers a high level of versatility and flexibility. Can use in the field of agriculture, HVAC system, laboratory, brewery, and commercial kitchens. Suitable for use in a variety of settings where controlling CO2 levels is important

SMART HOME FAQ

Not always.
Smart bulbs, plugs, cameras, and video doorbells are often easy DIY installations, while full security systems may need professional setup.
Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.

Smart Security Cameras
Smart Door Locks
Smart Thermostats
Smart Plugs
Video Doorbells
Yes.
