Descriptions
UbiBot WS4-A1RS1C CO2 Data Logger is a professional environmental monitoring device designed for applications requiring accurate, stable, and flexible sensing. It integrates high-precision temperature, humidity, light and CO2 sensors to deliver continuous real-time monitoring of critical conditions.
With an RS485 interface, the device supports external sensor expansion for customized monitoring needs. Dual-band WiFi (2.4 GHz / 5 GHz) ensures reliable data transmission, while Flight Mode disables wireless communication when required, maintaining local data logging for compliance in restricted environments.
An intelligent data acquisition system dynamically adjusts sampling and upload frequency, triggering alerts when thresholds are exceeded. With up to 300,000 local records, the WS4-A1RS1C continues recording during network outages and automatically syncs data once reconnected.
Protected by an IP65-rated enclosure and powered via Type-C with an internal lithium battery, the device supports flexible installation and long-term unattended operation. Fully integrated with the UbiBot IoT Cloud Platform, it provides centralized management, real-time visualization, and historical data analysis for agriculture, cold storage, laboratories, and industrial monitoring.

The WS4 series device has an IP65 protection rating, which effectively prevents dust ingress and resists low-pressure water jets. However, when exposed long-term to harsh outdoor environments (such as continuous rainfall, high humidity, or intense sunlight), there is still a potential risk of moisture or rainwater gradually infiltrating, which could affect the device’s long-term stability and service life.
It is recommended that for outdoor use, the device be installed in a weatherproof outdoor distribution box or other sheltered environment to enhance its reliability and durability in complex climatic conditions.

FAQ
1. Does the device collect data when the network is unavailable?
Yes. The device continues to monitor the environment even when no network is available. It stores the data in its on-device memory and will sync it when you move it to a WiFi environment. Alternatively, you can manually export the data via our PC Offline Tool or WiFi AP.
2. How to reset the device when my WiFi router password is changed?
Repeat the device setup steps and follow the on-screen instructions. Note: you need to type in the new WiFi password. All your data are kept unchanged when you changed the WiFi password or even you move the device to a new location.
3. Is there any subscription fee for using the platform?
There is no need for a subscription to use the UbiBot Platform.
- Each device comes with the free plan on UbiBot platform that offers 200MB storage and 1GB outbound traffic. The 200MB storage is for lifetime and 1GB of outbound traffic is rotated monthly for each device. But any balance of the outbound traffic will not roll over to the next month. For example, if you have 500 MB outbound traffic unused this month, you still have 1 GB next month.
- The free 200MB storage is enough to store over 2 years amount of data in case your device takes temperature, humidity, and light sensor readings every 10 minutes.
