People Counter Kit with ESP32-S3 & IoT Dashboard
Build an Entryway People Counter with ESP32-S3 & IoT Dashboard
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Track footfall in real-time on a local browser dashboard using infrared break-beam sensors and an ESP32-S3. Monitor a school lab, shop entrance, or college event - live counts without cloud fees. Ideal for CBSE class projects and Smart India Hackathon demos.
What You'll Build
Build a working IR break-beam counter that updates a web page over WiFi. The ESP32-S3 reads sensor pulses, hosts a simple server, and shows the count on a 0.96-inch OLED. Just connect any device to the same network, open the IP, and watch the tally live.
What You'll Learn
- Detecting beam breaks with IR LEDs and photodiodes through an LM393 comparator
- Configuring an ESP32-S3 to run an asynchronous web server
- Building a live-updating HTML dashboard using AJAX
- Displaying sensor data locally on an OLED screen

Who This Kit Is For
Ideal for CBSE Class 11-12 students building physics or computer science projects, first-year B.Tech ECE/EEE students needing a quick IoT demo, and ATL Tinkering Lab members exploring sensor networks. Also a ready-made solution for shop owners in India who want a low-cost footfall counter without monthly SaaS fees. If you're working on a Smart India Hackathon entry involving crowd analytics, this kit gives you a head start.
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 ask the AI companion that walks through each step, or send a WhatsApp message for human help during Indian business hours.
Can this counter differentiate between people entering and leaving?
With the two IR pairs, you can detect direction by monitoring the order in which beams break - the companion code includes logic for bidirectional counting so you get separate in/out counts.
Does it work without internet?
Yes, the ESP32-S3 creates its own WiFi access point or connects to a local network; the live dashboard works entirely on the local network without an internet connection.
Can I log data over time?
The AI companion provides optional code to store counts in SPIFFS or forward to a cloud platform like ThingSpeak if you later connect it to the internet.
