ESP32 Sensor Analytics Kit: Log Temp, CO2 & Humidity Trends
Monitor, Log, and Visualize Environmental Trends
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Picture a dashboard that updates every few seconds, showing temperature, humidity, and CO? levels from multiple rooms-all logged locally on your Raspberry Pi for weeks. This kit transforms an ESP32 and a handful of sensors into a powerful industrial-grade environmental logger. Whether you're monitoring a greenhouse, a server room, or an indoor farm, you'll have complete control over your data without cloud dependencies.
What You'll Build
You'll construct a multi-sensor logging station that reads DHT22, BMP280, and MH-Z19B sensors at regular intervals. The ESP32 pushes this time-series data over Wi-Fi to InfluxDB running on your Raspberry Pi. Then, using Grafana, you'll create interactive dashboards that display live metrics and historical trends.
What You'll Learn
- Interface DHT22, BMP280, and MH-Z19B CO? sensors with an ESP32 development board
- Set up a local InfluxDB time-series database on a Raspberry Pi for autonomous logging
- Design and configure Grafana dashboards for real-time environmental analytics
- Solder and permanently assemble a robust sensor enclosure for long-term deployment

Who This Kit Is For
Ideal for B.Tech ECE/EEE students building capstone IoT analytics projects, Smart India Hackathon teams prototyping environmental solutions, and research scholars who need a dependable local time-series logger for indoor climate studies or agricultural experiments.
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?
Our AI companion solves 90% of queries instantly; if not, WhatsApp us for a human engineer who knows this exact kit.
Do I need a Raspberry Pi? Is it included?
A Raspberry Pi (any model with Wi-Fi) is required to run InfluxDB and Grafana locally. It is not included; you can use your own or buy one from our store.
Can I access the dashboards from my phone?
Once Grafana is running, you can open its web interface from any device on the same network. For remote access, you'll need additional port forwarding-the AI guide can help advanced users.
How much data can this logger store?
Storage depends entirely on your Pi's SD card size. At a 10-second logging interval, a 32 GB card holds over a year of three-sensor data.
ESP32 logs sensor data to InfluxDB running on a local Raspberry Pi. Grafana visualises trends over weeks.
