Why Dr.STEM

Why schools choose Dr.STEM

A ready-made solution that covers the core topics of science lessons, scales easily and gives students hands-on experience with real data from the very first lesson.

Modular

The system grows with your school: add sensors and kits step by step.

Quick setup

Connect and start an experiment in under two minutes. No complex installation.

Data visualisation

Students see graphs in real time and analyse changes in the readings straight away.

Fair price

A well-balanced kit price for highly functional equipment.

Curriculum coverage

Covers core topics of secondary-school physics, chemistry, biology and geography.

Support

Ready-made lesson scenarios, experiment instructions and technical advice at every stage.

What Dr.STEM includes

Five components, one solution

From the display device to ready-made lesson scenarios, everything works as one system.

Tablet / laptop

Device for displaying, processing and saving data (chosen by the customer).

Central module

The unit the sensors connect to. It connects to the computer via USB.

Sensors

Modular devices for measuring temperature, pressure, pH, light, sound and more.

Software

An intuitive program for data visualisation, graphs and saving results.

Teaching materials

Ready-made lesson scenarios and experiment instructions for teachers.

The equipment

Real hardware, clearly labelled

Every sensor is a compact module in its own case with a clear label. The sensors connect by cable to the central module, which links to a tablet or laptop.

Sensor modules: voltage, current, magnetic field, pH, light, UV, CO₂, conductivity and contact temperature

Kit options

Choose a kit for your subject

Five ready-made configurations, each with its own set of sensors and the key topics it covers.

Physics

Mechanics, thermal phenomena, electricity, waves and sound.

14 sensor types
Order kit

Each kit comes in a teacher version (one per class) and a student version (one per group of 5–6 students).

Sensors in the kit

TemperatureAbsolute gas pressurepHCO₂LightUltravioletECGHeart rateOxygenSoil moistureMulti-sensor

🔬 Key topics and sensors

RRespiration and photosynthesis — CO₂, illuminance, temperature
PHuman physiology — heart rate, CO₂, temperature, pH
EEnvironmental ecology — temperature, CO₂, UV, soil moisture
AAquatic ecosystems — temperature, salinity

Important: the ECG and heart rate sensors are educational demonstration sensors, not medical devices. They are meant for showing how the heart works and for school experiments, not for diagnosis or clinical use.

Geography

Weather and microclimate, atmosphere, water and soils, the Earth’s magnetic field and solar radiation.

💬 Customisation examples

“We focus on ecology” → add more air and water quality sensors
“Physics only, lower secondary” → fewer chemistry and biology sensors, focus on mechanics
“We want STEM projects” → extend the set for interdisciplinary experiments

Dr.STEM software

Data collection and visualisation in real time

The Dr.STEM software reads data from the sensors and instantly turns it into graphs that students work with during the experiment.

Real-time sensor readings
Interactive graphs to explore changes
3 data display modes
Standard calculations
Library of school experiments
Game mode (gamification)

The experiment becomes a dialogue, not just a measurement

An AI consultant is built right into the experiment. Students look at the graph and can ask straight away:

Why does the curve change its slope?
What does this peak mean?
Which physical process is happening right now?
Interprets the data together with the student
Helps to form hypotheses
Reveals natural phenomena in more depth
Game mode

We turn the lab into a team game

Gamification turns the experiment into a competition in which teams complete missions based on real data.
