One device, many metrics

The UbiBot WS1 has industrial-grade sensors that work seamlessly to give you accurate sensing of environmental conditions. The optional external temperature probe allows you to monitor liquids, soil and other harsh environments.

Temperature Sensor

Precision:        ±0.3℃
Range:   -20℃ to 60℃
              (-4℉ to 140℉)
Humidity Sensor
Precision:      ±3% RH
Range: 10% to 90% RH
Ambient Light Sensor
Precision:              ±2%
Range:   0.01 to 83K lux
Vibration Index Sensor
Precision:   4mg
Range: -16 to 16g
External Temperature Sensor
Precision:      ±0.5℃
Range:   -55 to 125℃
              (-67 to 257ºF)

The sensor precision might fluctuate slightly in actual usage because of environment condition, deployed position, etc. See user guide for detailed parameters.
⚠️The device is not waterproof. For outdoor use or indoor environment with a constant 90% or higher humidity, please use a waterproof case and connect an external probe.

A revolutionary cloud-based solution

The UbiBot WS1 can connect to the network using WiFi. It automatically synchronises its data to the UbiBot IoT Platform. This gives you secure access to your monitoring data from anywhere in the world via the website or our App.


Even if the network fails, the WS1 won’t let you down

The UbiBot WS1 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. You can also download the stored data manually by connecting the recorder directly to your computer.


Stylish Design and Impressive Features

We are on a mission to revolutionise your environmental data sensing. WS1 is the most accurate WiFi sensor device and offers real-time alerts.

International Certificates

UbiBot devices have received multiple certifications, including CE, FCC, IC, RCM and RoHS. We also comply with all relevant standards for GSM and WiFi devices. Compliance with these regulations enables UbiBot devices to be sold in many major markets including the US and EU. We are actively seeking additional certifications in order to further widen our market.


Unlimited Applications

With its wireless monitoring capabilities and online access to the data, our multi-sensor WS1 has been used in numerous industries, including intelligent agriculture, inventory management, pharmaceutical storage and server room monitoring. Get peace of mind with a simple 3 minute setup.

Historic silk textiles are extremely precious and need to be carefully preserved. The slightest change in temperature or humidity could damage them. Museum curators can use the WS1 to monitor the environment remotely and will receive an alert if conditions ever change.
Wine is best kept at 50-70% relative humidity and needs a consistent cool temperature. By installing UbiBot® WS1 sensors in your wine cellar you are assured that you will be notified of any deviation from the ideal conditions.
The UbiBot WS1 gives museum curators and gallery owners peace of mind by providing real-time visibility of environmental conditions and configurable alerts when conditions go outside safe bounds.
Environmental conditions are critical when storing medications. UbiBot gives you round the clock monitoring of storage conditions to ensure quality and safety.
Servers are sensitive to extremes of heat and humidity. To keep them safe businesses can combine our wireless monitoring device with customised alerts to warn them when things are getting critical.
Real-time monitoring is vital in intelligent agriculture and horticulture. Because the WS1 offers automatic syncing of data, you can monitor conditions remotely through our App or via the UbiBot IoT Platform.
