Wireless Smart Multi-Sensor IoT Device
with LCD Display
2.4GHz WIFI Version
~ EC, pH, Temperature and Light~
(Model No.: GS2-EL)


UbiBot ® GS2-EL is a wireless EC & PH value remote monitoring device, specially designed for the agricultural hydroponic industry.

GS2-EL includes 1 x DS18B20-Audio Temperature Probe, 1 x EC probe, 1 x PH probe, and has a built-in ambient light sensor. Once configured with WiFi connection, GS2-EL measures the temperature, EC and PH value of the liquid, and syncs data automatically to UbiBot ® IoT cloud platform, allowing you to access data and monitor the environment remotely from anywhere in the world via the free UbiBot APP or Web Console and to receive real-time alerts.

There are on-board knobs for the EC/PH probes accuracy calibration.

We also provide and recommend do-it-yourself automatic calibration that you can perform using the UbiBot Web Console.

GS2-EL is industrial grade, IP65 dustproof and water-resistant for harsh environment.

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 GS2 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 2900mA batteries ensure a long working time.
