Soil Temperature and Moisture Sensor
Monitoring the soil temperature and moisture with an embedded RS485 communication protocol interface
The Soil Temperature and Moisture Probe efficiently monitors the temperature and moisture of soil. With an embedded industrial-grade chip, the probe offers accurate measurement. The stainless-steel probe can be inserted into the soil for a long term without corroding. The durable cable ensures stable data transmission.
The Soil Temperature and Moisture Probe measures soil moisture content based on the frequency domain reflection method (FDR).
The probe comes with a Micro USB or a 3.5 mm audio plug. The Micro USB plug works with WS1 Pro, the audio plug works with GS1 and SP1 series.
The measurements are transferred to the devices, displayed on the LCD screen, and synced to UbiBot Cloud Platform via the WiFi/GSM/Ethernet network; this allows you to access the data instantly on the screen and remotely via the UbiBot App or Web Console.
The moisture readings on the Web Console can be switched between Relative Moisture and Absolute Moisture. You can configure the display on the Web Console.
Application Instructions
For a short single use:
Insert the steel probe point vertically into the soil at your preferred depth. Hold the probe tightly to prevent shaking. Avoid touching stones or any other hard objects because that can damage the probe. Please wait for about 20 minutes to allow the sensors to start working properly.
For a long-time use buried in soil:
Dig a hole of over 20 cm in diameter in the ground or soil in your greenhouse. Lay the steel probe horizontally into the hole. Leave the probe in the soil. Access the data collected by the probe remotely.
About moisture readings:
All the UbiBot Soil Temperature and Moisture Probes have been calibrated in the factory. Calibration including data points is conducted by placing the probe in the air to reach the minimum of 0% moisture and in soil with completely watered to reach the maximum of 50% moisture. The default readings are Absolute Moisture readings. If you prefer Relative Moisture, please go to the Web Console to set it up.
If you have strict requirements for measurement accuracy, and you want to achieve the highest accuracy, you will need to use UbiBot Probe Calibration Tool with USB-RS485 Adapter to periodically calibrate the probe.
Features:
- Soil temperature and moisture monitoring
- RS485 ModBus Protocol makes sure data transmission is accurate and stable
- Supporting Absolute Moisture and Relative Moisture switching
- Can be calibrated with UbiBot Probe Calibration Tool
- Measuring Temperature Range: -40 °C～+85 °C; Measuring Moisture Range : 0～50% (Absolute Moisture)
- Accuracy: <±0.4 °C; ±3% (0-50%); ±5% (>50%)
- Working with WS1 Pro, GS1 series, and SP1
- IP68
Note:
- Only one Soil Temperature and Moisture Probe can be connected to a UbiBot device at a time.
- Soil Temperature and Moisture Probe should be connected to the lower USB port (USB2) on the WS1 Pro device.
- The Soil Temperature and Moisture Probe is disabled by default. Please enable it in "Settings" in the App or the Web Console after connecting the probe to the device. The button "RS485 S" refers to the Soil Temperature and Moisture Probe. The GS1 device doesn't need this operation.
- This product is designed to work exclusively with UbiBot devices.
WARNING:
The probe’s end is very sharp. Be careful when using it and keep it away from children.

Real-time and history data
The UbiBot Platform is a cloud-based IoT platform where all measured data is uploaded and stored. UbiBot App and Web Console allow you to view current data as well as historical data in graphs. The adjustable Y-axis scale allows you to view any tiny fluctuations in the curve.
Customizable alerts and bulk operation
Setting and receiving alerts on your devices helps you to get notified of the conditions timely. When you have many devices to manage, it’s time-consuming to set each alert rule one by one. Therefore, we’ve developed a bulk operation module with which you can set the same rule for many devices at a time.
Free data export
On UbiBot Platform, you can download the history data in CSV or PDF format. The CSV file only contains raw data, while the PDF file is a summarized report with average, maximum and minimum value within the chosen period. The PDF file is much easier to read and archive.
Device sharing and bulk operation
For business users, centralized control over multiple devices is available, with no limit on the number of devices in one account. Also available are bulk operations that apply to sensor settings, alerts, and remote control routines. Devices can be shared with other people, which allows for distributed management by different colleagues.
Intelligent automation in UbiBot platform
UbiBot is committed to building intelligent industrial and home ecosystems. By integrating temperature and humidity sensors and the smart plug SP1 in one system, automated operation is achieved through data linkage. For example, fans can be switched on when the temperature rises to 30 °C.
Data forwarding
UbiBot is an open platform that provides cloud-based services while supporting customers to use their own storage servers. With the data forwarding service, you can forward the data collected by your device to your own private URL to protect privacy.
Location tracking and logging
UbiBot GS1-PL4G1RS is embedded with GNSS (Global navigation satellite system) for positioning. Through mobile data communication, real-time location information is transmitted to the platform and recorded. The UbiBot platform integrates this data, plots it into a trajectory map, and presents it.
Platform-based calibration
UbiBot platform supports data calibration both on the platform level as well as the device level. One-step calibration, instant display, no impact on historical data.
SIM card management
When using UbiBot Global SIM to transfer data, you can manage it by yourself. Unlike other SIM cards with a standard monthly fee and traffic amount, our SIM supports many types of plans. Choose the one that suits you now, and change to another next time. No arrearage and no extra charge.
