ESP32 BLE HVAC Kit: Wireless Temperature & Humidity Sensor
ESP32 BLE HVAC Kit: Wireless Temperature & Humidity Sensor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll assemble a portable sensor that continuously measures temperature and humidity, then transmits the readings as BLE advertisement packets. No pairing required-any phone or ESP32 scanner can pick up the data from across the room. Use it to track HVAC performance, log microclimate conditions, or trigger home automation rules based on real-time environmental data.
What You'll Build
Once built, the device runs on a LiPo battery and broadcasts environmental data every second. You can view the real-time payload on a smartphone app like nRF Connect, or integrate the BLE feed into custom dashboards. This is a compact, low-power monitor ideal for checking AC efficiency, server room conditions, or classroom science experiments.
What You'll Learn
- Configure an ESP32-C3 to broadcast custom BLE advertisement data without bonding
- Interface the DHT22 sensor and read temperature/humidity with precise timing
- Power the circuit with a LiPo battery and TP4056 charging module for portable use
- Decode BLE payloads on a smartphone or secondary ESP32 receiver

Who This Kit Is For
Designed for CBSE Class 11-12 students exploring IoT with ESP32, B.Tech ECE/EEE learners tackling wireless sensor networks, Smart India Hackathon teams building rapid prototypes, ATL Tinkering Lab innovators, and any hobbyist who wants a ready-to-deploy BLE beacon for environmental monitoring.
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?
The AI companion provides step-by-step troubleshooting, and you can send a WhatsApp message for direct engineer support within hours.
Do I need any prior coding experience to set up BLE advertising?
The kit includes pre-flashed firmware that works out of the box. If you want to modify it, the companion walks you through every line of Arduino code.
How can I view the sensor data on my phone?
Use any BLE scanner app like nRF Connect or LightBlue. The temperature and humidity appear right in the advertisement packet, no pairing or special software needed.
Can I power the monitor from a wall outlet instead of the battery?
Yes, you can supply 5V via the Micro USB cable to the TP4056 module, which will both power the circuit and charge the LiPo cell.
HVAC - ESP32-C3 broadcasts DHT22 temperature and humidity as BLE advertisement payload. No bonding needed.
