Project Details

The ESP32 Indoor Positioning System (IPS) leverages UWB technology for high-precision real-time location tracking. The system uses ESP32 boards as anchors and tags to determine the position of moving objects inside buildings or rooms. Applications include asset tracking, smart home automation, robotics navigation, and indoor navigation systems. Anchors are placed at known positions, and the tag sends UWB signals to all anchors. Anchors reply to the tag signal using Two-Way Ranging (TWR), and the ESP32 calculates distances from signal timing. Triangulation determines the tag's (X, Y) location, with real-time positions displayed on a serial monitor or dashboard.

How It Works

The system uses ESP32 boards as anchors (fixed positions) and tags (mobile objects). Anchors are placed at known positions in the room. The tag sends a UWB signal to all anchors. Anchors reply to the tag signal using Two-Way Ranging (TWR) to measure distance. The ESP32 calculates distances from signal timing. Triangulation or multilateration determines the tag's (X, Y) location. Real-time positions are displayed on a serial monitor or dashboard.

Prerequisites

Basic knowledge of ESP32 programming, SPI communication, and basic electronics. Familiarity with Arduino IDE and C++ programming is recommended. Understanding of basic trigonometry for position calculation is helpful.

Frequently Asked Questions

Q:Can this track multiple tags?

A: Yes, with multiple ESP32-UWB tags and anchors. The system can be scaled to track multiple moving objects simultaneously.

Q:Is UWB safe?

A: Yes, UWB is low-power and safe for humans. It operates within regulatory limits for indoor positioning applications.

Q:Can ESP32 alone do trilateration?

A: Yes, but you may need multiple ESP32 anchors for best accuracy. The ESP32 can calculate positions using distance measurements from multiple anchors.
