Serverless AWS Lambda Sensor Trigger Kit with ESP32 + DHT22
ESP32 + DHT22 to AWS Lambda: A Complete Serverless Sensor Pipeline You Assemble and Code
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Every minute, millions of IoT devices push sensor data to the cloud without a single always-on server. This kit lets you build one yourself—a compact ESP32 board that reads ambient temperature from a DHT22 and atmospheric pressure from a BMP280, displays readings on an OLED screen, then securely sends the data via HTTPS POST to AWS API Gateway. A Lambda function, written by you with AI guidance, processes the payload and logs it into DynamoDB. It’s a miniature but fully functional serverless architecture you can hold in your hand, perfect for advanced projects, hackathons, or your engineering final year.
What You'll Build
You wire the sensors and OLED onto a prototype board, power everything through a buck converter, and enclose it in a ready-made box. With the Arduino IDE, you program the ESP32 to connect to WiFi, read DHT22 and BMP280, format a JSON payload, and establish a secure HTTPS connection using a root certificate. On AWS, you configure an API Gateway REST endpoint with Lambda proxy integration, deploy a Node.js or Python function that validates the data and writes it to a DynamoDB table. The local OLED shows real-time readings and upload status, giving you an end-to-end cloud-connected sensor node.
What You'll Learn
- Designing a TLS‑encrypted HTTPS POST from ESP32 to AWS API Gateway
- Creating an API Gateway trigger that invokes a Lambda function without any server
- Writing a serverless function to parse sensor JSON and insert it into DynamoDB
- Integrating a local OLED display and stable power supply for field‑ready operation

Who This Kit Is For
Advanced makers, B.Tech ECE/EEE students sharpening cloud skills for the Smart India Hackathon, final‑year project candidates from IITs/NITs/VIT/BITS, and any IoT enthusiast ready to move beyond local dashboards. If you’ve already worked with Arduino or ESP and want to demonstrate a genuine serverless architecture on your resume, this kit bridges the gap with a real, deployable project.
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 on the box to launch the AI companion, which knows every sensor connection and AWS configuration step. For anything else, drop a WhatsApp message—we reply within hours.
Do I need an AWS account, and are there costs?
Yes, you’ll need a free AWS account. The AI companion helps you stay within Free Tier limits; typical usage for this project stays completely free.
Is soldering experience required?
The kit includes a soldering iron and wire; you’ll solder sensor headers, the OLED, and power leads. The AI companion provides close-up videos and guides even if you’re new to soldering.
Can this kit be used for a B.Tech major project?
Absolutely. The serverless data pipeline is a cutting‑edge topic, well‑documented, and the project report‑friendly architecture makes it a strong final‑year or hackathon submission.
ESP32 sends HTTPS POST to API Gateway which triggers Lambda function to log data to DynamoDB.
