ESP32-C3 BLE Sensor Beacon Kit with ESP32 + DHT22
ESP32-C3 BLE Sensor Beacon Kit: Broadcast Temperature and Humidity Without Pairing
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Monitor a server room from your phone without pairing, or check greenhouse humidity from across the hall—without cloud, without bonding. This kit lets you build a battery-powered ESP32-C3 beacon that reads a DHT22 sensor and encodes temperature and humidity directly into BLE advertising packets, viewable on any scanner app. It's a real IoT skill: raw data on air, no pairing, no gateways.
What You'll Build
You'll assemble an ESP32-C3 Super Mini with a DHT22 sensor, power it from a 3.7V LiPo battery and TP4056 charging module, and program it to broadcast environmental data continuously. The finished beacon can sit in a drawer, a plant bed, or a server rack—sending live readings to your phone the moment you open a BLE scanner.
What You'll Learn
- Encode temperature and humidity into BLE advertising payloads
- Configure ESP32-C3 for low-power BLE broadcasting without bonding
- Interface DHT22 one-wire sensor for precise climate readings
- Design battery-powered embedded systems with LiPo and TP4056 charger

Who This Kit Is For
Ideal for B.Tech ECE/EEE students building their first wireless sensor node, for CBSE Class 12 students exploring IoT as a Computer Science elective, and for Smart India Hackathon teams prototyping environmental monitoring systems. Also suits ATL Tinkering Labs and hobbyists at NIT/VIT/BITS who want to learn BLE advertising without complex pairing logic.
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 kit box to access the AI build companion, which walks you through troubleshooting this exact project. You can also message us on WhatsApp for human backup.
Can I see the broadcasted data on my phone?
Yes, any BLE scanner app like nRF Connect or LightBlue can display the advertising data. The companion decodes the payload so you can read temperature and humidity directly.
How long does the battery last?
With the 500mAh LiPo and ESP32-C3 in advertising mode, expect 4-6 hours of continuous broadcasting. The TP4056 module lets you recharge via Micro USB, so it's ready for extended experiments.
Is soldering required?
No, all connections use the breadboard and male-male jumper wires. This is completely plug-and-play, letting you modify or disassemble the circuit easily.
ESP32-C3 broadcasts DHT22 temperature and humidity as BLE advertisement payload. No bonding needed.
