The SensorTree platform
Monitor, alert, control and automate in one place.
Everything after the sensor runs in the SensorTree dashboard, the same one used for every device you connect.
Every channel, live, against its limits.
Readings arrive as devices report and are organised by site and group, so each line, machine and plant room has its own view.
- Live values and trends for every sensor channel
- Low and high limits drawn on each chart
- Device status, so you know when a sensor stops reporting
- Omni-view: the channels you choose, together on one screen
Alerts that reach someone who can act.
Each channel has its own limits and severity. If an alert is not acknowledged, it keeps reminding and moves up the chain.
- Severity levels per channel
- Notifications by SMS, email and app
- Reminders until someone acknowledges
- Escalation to the next person in the chain
Adjust equipment without walking the floor.
On devices with control channels, operators can change set points and switch outputs from the dashboard.
- Change set points remotely
- Switch outputs on compatible devices
- See each control channel next to its readings
Run equipment on a schedule.
Turn compatible equipment on and off at set times, on a repeat that matches your shifts.
- Daily, weekly, monthly or custom repeats
- Start and end dates, times and durations
- Enable or pause a schedule at any time
From simple rules to closed-loop control.
Choose the kind of automation the process needs. Automation runs on devices that support it.
- Rule-based: if conditions are met, then act
- PID: control loops with tuning parameters
- Advanced: PID with feed-forward settings
Screens are illustrative. Control, schedules and automation need devices with compatible control channels.

Process capability
X-bar and R charts, the last 25 subgroups, a capability histogram, normal probability and capability plots for a sensor channel.
Uptime reports
Availability by site, group and device type, so gaps in coverage are easy to find.
CSV & PDF exports
Export readings from the dashboard for audits, shift reports and your own analysis.
SensorTree AI Help

Industrial questions, answered.
Can't find what you need? Our team can confirm ranges, interfaces and how a device fits your setup.
Ask a questionWhat can I monitor with SensorTree industrial sensors?
The industrial range covers line pressure, liquid flow in pipes, machine vibration, air quality and humidity, electrical energy use and water quality. The specification table on this page lists the measurement range, accuracy and interfaces of each product.
Which outputs and interfaces do the sensors provide?
They differ by product and are listed in each specification. For example, the PT-500 pressure transmitter lists 4-20 mA with HART, the FM-600 flow meter lists RS485 (Modbus RTU) and 4-20 mA, and the VS-400 vibration module lists LoRaWAN and BLE 5.0. Use the interface filter above the specification table to compare them.
Do wired sensors need extra hardware to connect?
Wired outputs such as 4-20 mA, HART or RS485 (Modbus RTU) need a compatible gateway or controller to reach the platform. Tell us your equipment and existing controls, and we will confirm how a specific device connects to your setup.
How are alerts handled for abnormal readings?
You set limits and a severity for each channel. When a limit is crossed, the platform notifies the right people by app, email or SMS. If nobody acknowledges, reminders repeat and the alert escalates to the next person in the chain.
Can I control and schedule equipment remotely?
Yes, for devices with control channels. You can change set points and switch outputs from the dashboard, and create daily, weekly, monthly or custom schedules that run equipment at set times.
What kinds of automation are available?
Rule-based automation checks one or more conditions and then acts, for example alerting people or switching an output. For control loops there is PID automation with tuning parameters, and advanced automation, which adds feed-forward settings to PID control. Automation needs devices that support it.
Can I analyse process stability, not just live readings?
Yes. Process capability analysis works on a sensor channel over a period you choose and shows X-bar and R charts, the last 25 subgroups, a capability histogram, a normal probability plot and a capability plot. Dashboards also export readings to CSV or PDF, and uptime reports show availability by site, group and device type.
Can I monitor several sites from one place?
Yes. Devices are organised by site and group in one dashboard, so teams can see every facility and what needs attention first.
Can I buy online, or do I need a quote?
Products with a published price can be added to the cart and bought online once you sign in. For larger quantities, multi-site rollouts, custom requirements or integration questions, request a quote and our team will recommend a setup.
