Product Overview

Wireless Smart Multi-Sensor IoT Device
with LCD Display
2.4GHz WIFI and SIM Version
~ Temperature, Humidity, Light Level & CO2 ~
(Model No.: GS1-AL4G1RS-S+CO2 + 5V/2A Power Adapter)


WiFi and Mobile Network model:  The device can connect to both 2.4GHz WiFi router network and mobile GPRS/3G/4G networking using a SIM card. (SIM card is not provided). 

The UbiBot ® GS1 uses the cutting-edge IoT technologies to offer a more stable environmental monitoring with high performance. Embedded with WiFi and GPRS/3G/4G, it detects environmental data all day round and automatically syncs all the data to the UbiBot ®IoT Platform. The clear 4’’ screen allows you to instantly view the latest data. You can also access your device readings in real-time via our App or using a browser anywhere in the world. The embedded RS485 interface ensures your use of external probe in the most extreme conditions.

Our cloud-based IoT platform offers advanced data analysis and management. It also allows you to setup real-time notifications - if a metric goes outside the range you specify, the platform will notify you through the app, by email, SMS text, voice call and HTTP, allowing you to respond promptly before costly damage happens. Please note, charges may apply to SMS text and voice call alert modes. These two modes cost the balance of the credits in your account. The IoT platform gives users access to both the real-time data and history via our mobile app or on any browser. We are now working with IFTTT (if this then that), allowing you to build custom link with other smart devices.

The device can store up to 300,000 records in its internal memory, which can protect your data against network failure. Even if the network fails, the UbiBot GS1 still stores readings, thus ensuring there are no gaps in the data history.

The device supports three types of power supply: internal lithium batteries, Type-C 5V, and DC 12V. The 3000mA batteries ensure a long working time.
