ESP32 ThingSpeak Data Logger Kit – Build a Cloud Weather Station with DHT22 and LDR

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 building your own personal weather station that automatically logs temperature, humidity, and light intensity to a cloud dashboard – then seeing the data update every minute on your phone. This kit puts a real IoT project in your hands using the ESP32, DHT22, and two LDR sensors. The free ThingSpeak platform handles the storage and charting, so you can watch conditions change from anywhere without writing a single line of server code.

What You'll Build

You’ll wire the DHT22 and light-dependent resistors to an ESP32 on a breadboard, then upload a program that reads the sensors and sends the values over WiFi. The data appears as live charts in your ThingSpeak channel – temperature, humidity, and ambient light levels all trending in real time. Every 60 seconds a new data point appears, and the dashboard is instantly viewable on any phone browser.

What You'll Learn

• Connect a digital temperature/humidity sensor to the ESP32 and interpret its one‑wire protocol
• Build voltage‑divider circuits with LDRs and fixed resistors to measure light intensity on analog pins
• Use the ESP32’s WiFi and HTTP libraries to POST sensor readings to a cloud API (ThingSpeak)
• Configure a public dashboard with auto‑scaling charts and share it with family or teachers

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11‑12 students exploring IoT in computer science or physics, ATL Tinkering Labs running weather‑based projects, and beginners aged 5‑15 who want to see real sensor data on a phone. It’s also a quick, fail‑safe way for B.Tech ECE/EEE students to complete a cloud‑logging assignment during Smart India Hackathon prep or back‑to‑campus lab work.

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.
