The GS2 series is part of the UbiBot family of IOT sensors. The industrial grade GS2  has integral sensors for pH, conductivity and ambient light measurement. It also supports the use of an optional external temperature probe for monitoring temperature. Models are available with WiFi and 4G mobile cellular connectivity.

WiFi or 4G Mobile Connectivity for Easy Access Anywhere in the World

The GS2 device can connect to the network WiFi or 4G mobile cellular data. It measures environmental data 24/7 at the pace you set. It can upload and store your data securely on the UbiBot cloud platform. No matter where you are, you can view the sensor readings anytime using our mobile app or with any browser enabled device.

GS2 pH Data Logger Wireless Network

Super Clear Backlit LCD Screen

The GS2 has a bright and clear 4-inch LCD screen. This displays the current environmental conditions and shows you any alerts and notifications in real-time. The screen my also be backlit for easier viewing in dark environments.

Even if the Network Fails, the GS2 Won’t Let You Down

The GS2 boasts a large onboard memory and continues to collect and store data even when the network is down. If the network ever fails, you will receive a notification.

Industrial IP65 Water Resistant/Weather Tight Enclosure

The GS2 feature an IP65 enclosure. IP65 is dust tight and provides protection against low pressure water jets from any direction, as well as condensation and water spray making it suitable for most outdoor enclosures that won’t encounter extreme weather such as flooding.

Power by Battery or External Power Source

To offer industrial users a more suitable solution, we use 2900 mAh lithium battery for the GS2 device. Combined with low-power technology, the device has longer standby time for uninterrupted monitoring. It can operate completely from battery power or from an external power source with the batteries acting as a power back up in case of power failure. The GS2 may be externally powered by the included type-C USB cable or with the optional wall plug power adapter.   There is also an optional solar panel for operation in environments without power.

A Full Featured Cloud-based Platform For Monitoring, Logging and Alerts

The GS2 transmits data to the UbiBot cloud platform which allows users to view the data from any device which has internet access. The UbiBot Cloud Platform has many powerful features.

Data Management - Manage all your UbiBot IoT data in one location, extract clear insights and maximize its value. You always retain full control over your data.
Unlimited Storage - Unlimited cloud-based storage ensures you will never run out of space. This allows you to view all your historical data via the app or browser.

Analysis and Visualization - Use powerful analysis and visualization tools to get the most out of your data. Spot trends and make direct comparisons. View a screen image of the Cloud Console for a GS2 in action.

Real-time Alerts - Our fully customizable alerts system will notify you by app notifications or emails as soon as any metrics cross the thresholds you set. For a small optional fee you can also receive SMS (text) and Voice alerts.

Highly Secure Platform - Our platform is designed to keep all your data secure so you never have to worry about hackers or other security breaches.

The free cloud plan is a good solution for most users but we also offer several different levels of paid subscriptions for users with large number of units and large data storage requirements. The table below provides a comparison of the different plans.

UbiBot Cloud Plans


1. The storage space is cumulative and does not reset monthly but exporting all data will clear the storage space. If your device takes temperature, humidity and light sensor readings every 10 minutes, the free 200MB storage is enough to store over 2 years of data.

2. The Full Data Export amount is on a monthly basis (example 3 times per month for the free plan). If you only export the data collected over single month period, there is no limit on the number of exports as long as the export is less than 8000 records.

3. One credit equals $1 USD.


Cloud Platform Alarms, Alerts and Additional Features

UbiBot Platform Additional Features
The cloud platform allows you to set up a variety of alarm conditions. Alarms can be triggered when a measured values goes above or below a threshold. You can also trigger an alarm on low power or loss of WiFi connection. The console can also generate an alarm when a device goes off-line and comes back on-line. When an alarm condition occurs a variety of alert types can be sent to notify the user.

Email Alerts - Send an email alert when an alarm condition occurs.

IFTTT - UbiBot works with IFTTT (If This Then That), giving you an array of possibilities in monitoring your environments. With IFTTT you can trigger millions of different IFTTT events, such as turn on a light when GS2 senses light levels fall below 40 lux. Integration with IFTTT makes your smart devices talk to each other without manual intervention.

SMS Alerts - SMS text alerts can be set to your mobile devices.

Voice Call Alerts - UbiBot can even send an actual voice alert to your telephone.

UbiHTTP Alert - Allows communication between devices, websites, and Web services without implementing protocols at the device level. When an alarm condition occurs in the Cloud Platorm, UbiHTTP will send a HTTP request to a remote URL.

Data Forwarding Feature - The Data Forwarding will forward a copy of the original feed data from any UbiBot device to a given URL endpoint. This can be useful to seamlessly connect the UbiBot devices to third-party platform business logic or third-party application. This service requires activation on the UbiBot platform along with some development work on the data endpoint to correctly handle the incoming data feed.

Platform API - The UbiBot IoT platform allows you to collect, store, analyze and visualize data collected from UbiBot sensor devices, as well as create rules related to that data. All these functions are accessible via our RESTful API over HTTP.

SpreadSheets - The AutoSync Google Sheets Service allows you to transfer your data automatically into Google Sheets.

Alexa Integration- You can interact with your UbiBot devices by voice, you can setup routines to use readings from UbiBot temperature sensors as conditions to perform series of actions, such as turning on/off the heating and air conditioning.

Many of the alerts and features are free but some require and additional fee as shown in the fee schedule below.

UbiBot Additional Features Fee Schedule

One credit equals $1 USD

1. Threshold of 200 free alert emails per device per month is rotated monthly (If you own 10 devices, you would have 2000 free email alerts per month). Overage costs is 3 credits per thousand email alerts sent.

2 .We offer 3 free trials of data forwarding services for a new UbiBot device. Each trial is valid for 24 hours. Monthly fees will be charged if you would like to continue with this function.
