ESP32 BLE Mesh Positioning System Kit with ESP32 + DHT22
ESP32 BLE Mesh Positioning System Kit for Indoor Trilateration
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Deploy a functional indoor positioning system that pinpoints asset locations without GPS. Eight stationary ESP32 beacons form a BLE mesh network, measuring signal strength to a mobile asset tag. The system trilaterates the tag's coordinates with 1m accuracy in warehouses, labs, or campus corridors. This kit bridges the gap between theoretical wireless communication coursework and a tangible IoT deployment for your Smart India Hackathon prototype or final-year project.
What You'll Build
A fully operational indoor location engine. You will flash BLE beacon firmware onto eight ESP32 boards, mount them in enclosures at known coordinates, and calibrate the radio environment using RSSI data from a ninth mobile ESP32. The system outputs real-time positional data through the serial monitor, with visual feedback from LEDs on each anchor. Beyond trilateration, each anchor doubles as an environmental node by reading the DHT22 sensor, giving you a mesh that tracks both assets and ambient conditions across a floor plan.
What You'll Learn
- Implement BLE mesh networking and message flooding across multiple ESP32 nodes
- Apply trilateration algorithms using RSSI signal strength measurements from known anchor points
- Configure ESP32 boards in a multi-role architecture with one scanner and multiple advertisers
- Assemble and solder sensor circuits from schematic, including decoupling and pull-up requirements

Who This Kit Is For
B.Tech ECE and EEE students building final-year projects on indoor navigation or asset tracking. Smart India Hackathon teams needing a ready-made hardware backbone for a warehousing or hospital logistics solution. IIT, NIT, and VIT research scholars prototyping indoor localization algorithms before publishing. If you have prior experience with Arduino IDE and can read a simple schematic, this kit moves you from theory to a publishable working demonstrator in a single weekend.
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 start a session with the AI companion trained on this specific kit. If you need human help, message us on WhatsApp, and our lab team in Bengaluru will walk you through the RSSI calibration or soldering step that has you blocked.
How do I calibrate the anchor positions for 1m accuracy?
The AI guide includes a calibration walkthrough where you place the asset tag at known points one meter apart. It logs RSSI values against actual distances, refines the path-loss exponent, and feeds the corrected constant into your trilateration sketch for room-specific precision.
Can this system scale beyond one room for a campus-wide project?
The BLE mesh supports multiple subnets. You can partition your eight anchors into two clusters for adjacent zones. The core trilateration logic remains the same; additional ESP32 boards can be purchased as add-ons and flashed with the same firmware provided in the kit documentation.
Is soldering experience mandatory for this advanced kit?
Yes. You will solder DHT22 sensors, LEDs, resistors, and decoupling capacitors onto eight prototyping boards. A soldering iron and lead-free solder wire are included. A steady hand and prior through-hole soldering practice are assumed at this skill level.
Eight BLE anchor beacons with known positions trilaterate asset tag position to 1m accuracy indoors.
