Ubibot External CO2 Probe

CO2 concentration measuring & monitoring 24/7 with real-time alerts



- +

  • Matches with Ubibot GS1 devices
  • Readings can be displayed on the GS1 screen
  • Remote access via the app or web console
  • Multiple modes of alert notify you when the readings going over the normal range

UbiBot CO2 Probe is an industrial-grade probe that can measure CO2 concentration levels in a range of 0-40000 ppm, with an accuracy of ± (50 ppm + 5% in 400-2000 ppm). It features super stability and anti-interference ability, strong product protection performance, and first-grade lightning protection. This probe can be used in the agricultural industry and in places like laboratories, pharmacies, workshops, warehouses, museums, offices, and wherever carbon dioxide concentration levels need to be monitored.

By integrating UbiBot CO2 Probe with GS1 and SP1 device, you don't need to watch the readings all the time. All the data collected by the probe over time can be stored on our cloud platform and accessed from the UbiBot App and the Web Console. The custom alerts will notify you of any sudden change or extreme conditions via App notifications, emails, SMS text messages, voice call, and HTTP. Our cloud platform works with IFTTT (if this then that), which supports automation with your other electronic appliances, such as fans, ventilation system, etc.

The CO2 data, as well as other data on our system, comes with free data export, long term storage, and data forwarding options.

If you have strict requirements for measurement accuracy, and you want to achieve the highest accuracy, you will need to use UbiBot Probe Calibration Tool with USB-RS485 Adapter o periodically calibrate the probe.

Real-time and history data

The UbiBot Platform is a cloud-based IoT platform where all measured data is uploaded and stored. UbiBot App and Web Console allow you to view current data as well as historical data in graphs. The adjustable Y-axis scale allows you to view any tiny fluctuations in the curve.

Customizable alerts and bulk operation

Setting and receiving alerts on your devices helps you to get notified of the conditions timely. When you have many devices to manage, it’s time-consuming to set each alert rule one by one. Therefore, we’ve developed a bulk operation module with which you can set the same rule for many devices at a time.

Free data export

On UbiBot Platform, you can download the history data in CSV or PDF format. The CSV file only contains raw data, while the PDF file is a summarized report with average, maximum and minimum value within the chosen period. The PDF file is much easier to read and archive.

Device sharing and bulk operation

For business users, centralized control over multiple devices is available, with no limit on the number of devices in one account. Also available are bulk operations that apply to sensor settings, alerts, and remote control routines. Devices can be shared with other people, which allows for distributed management by different colleagues.

Intelligent automation in UbiBot platform

UbiBot is committed to building intelligent industrial and home ecosystems. By integrating temperature and humidity sensors and the smart plug SP1 in one system, automated operation is achieved through data linkage. For example, fans can be switched on when the temperature rises to 30 °C.

Data forwarding

UbiBot is an open platform that provides cloud-based services while supporting customers to use their own storage servers. With the data forwarding service, you can forward the data collected by your device to your own private URL to protect privacy.

Location tracking and logging

UbiBot GS1-PL4G1RS is embedded with GNSS (Global navigation satellite system) for positioning. Through mobile data communication, real-time location information is transmitted to the platform and recorded. The UbiBot platform integrates this data, plots it into a trajectory map, and presents it.

Platform-based calibration

UbiBot platform supports data calibration both on the platform level as well as the device level. One-step calibration, instant display, no impact on historical data.

SIM card management

When using UbiBot Global SIM to transfer data, you can manage it by yourself. Unlike other SIM cards with a standard monthly fee and traffic amount, our SIM supports many types of plans. Choose the one that suits you now, and change to another next time. No arrearage and no extra charge.
