Python Sensor Logger with Arduino Real-Time Control
Build a Dual-Platform Sensor Logger — Python on Linux, Arduino on STM32 for Real-Time Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine logging temperature, humidity, and pressure every second to a professional time-series database, while an Arduino sketch triggers relays and adjusts PWM based on sensor thresholds — all without a single delay. This kit places you at the exact intersection where Python data engineering meets hard real-time embedded control, a workflow used in industrial automation and smart infrastructure projects across India.
What You'll Build
You will assemble a complete environmental monitoring station that streams DHT22 and BMP280 readings from an Arduino UNO Q to a Python script running on Linux. The data gets stored in InfluxDB, ready for Grafana dashboards. Simultaneously, the Arduino sketch handles relay switching and PWM modulation based on sensor thresholds, giving you deterministic control that pure Python on Linux cannot achieve alone. By the end, you will have a deployable prototype for smart greenhouses, server rooms, or campus weather stations.
What You'll Learn
- Write Python scripts that communicate with Arduino over serial and ingest data into InfluxDB
- Configure and calibrate DHT22 and BMP280 sensors for accurate environmental readings
- Develop Arduino sketches for STM32 to manage relays and PWM outputs in real-time response loops
- Integrate a 0.96-inch OLED display to show live sensor data locally without a PC

Who This Kit Is For
This kit is designed for B.Tech ECE and EEE students who want to move beyond basic Arduino projects and into serious data engineering. It aligns perfectly with Smart India Hackathon prototypes, ATL Tinkering Lab advanced modules, and IIT/NIT/VIT/BITS project submissions where sensor fusion and real-time control are evaluated. CBSE Class 12 students with Python basics can use this as a capstone for computer science practicals.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code inside the box to launch the AI companion with step-by-step debugging help. You can also send a WhatsApp message directly from that interface for human backup within 24 hours.
Do I need prior experience with Python and Arduino?
Basic familiarity with Python variables and serial communication helps, but the AI guide provides complete code explanations and wiring diagrams. An intermediate maker can complete this kit without external tutorials.
Can I run the Python side on a Raspberry Pi instead of a Linux PC?
Yes, a Raspberry Pi OS (or any Linux distribution) will work. The kit does not include a Pi, but the Python scripts and InfluxDB setup are platform-agnostic.
What real-world applications can I demonstrate with this kit?
This is a miniature version of data acquisition systems used in smart agriculture, industrial cold storage monitoring, and building automation. Use it for campus weather stations, IoT hackathon demos, or academic projects requiring time-series data with control actions.
Python on Linux logs DHT22 + BMP280 to InfluxDB. Arduino sketch on STM32 handles relay and PWM in real time.
