Pin Types
Quick Tips
I²C address: 0x29 (fixed, not configurable)
Pull-up resistors on SDA/SCL may already be on the module
INT pin is useful for interrupt-driven measurements instead of polling
Pin Descriptions
| Pin Name | Type | Description | Notes |
|---|---|---|---|
1 VIN | Power | Power supply input (3.0V – 5.0V) | Accepts both 3.3V and 5V logic |
2 GND | Power | Ground connection | Connect to ESP32 ground |
3 SDA | Communication | I²C Data line | Bidirectional data signal for I²C communication |
4 SCL | Communication | I²C Clock line | Clock signal provided by ESP32 master |
5 INT | Control | Interrupt output | Optional - triggers when new measurement is ready |
6 SHUT | Control | Shutdown control (active low) | Pull high to enable, or use GPIO for control |
Wiring TOF200C to ESP32
Connect the TOF200C sensor to your ESP32 microcontroller using the I²C interface. The sensor operates on 3.3V or 5V and provides accurate distance measurements up to 200cm.

Pin Connections
| TOF200C Pin | Connection | ESP32 Pin | Description |
|---|---|---|---|
1 VIN Required | 3.3V or 5V | Power supply pin | |
2 GND Required | GND | Ground connection | |
3 SDA Required | GPIO21 | I²C Data line (default SDA) | |
4 SCL Required | GPIO22 | I²C Clocgk line (default SCL) | |
5 INT Optional | Any GPIO | Interrupt output (optional) | |
6 SHUT Optional | VCC or GPIO | Shutdown control (tie to VCC to enable, or use GPIO for control) |
The sensor works with both 3.3V and 5V logic levels
Ensure proper I²C pull-up resistors (4.7kΩ recommended) if not already on board
GPIO21 and GPIO22 are the default I²C pins on ESP32, but you can use any GPIO with software I²C
The INT pin can be used for interrupt-driven operation to reduce polling overhead
TOF200C Troubleshooting
Common issues and solutions to help you get your sensor working
Common Issues
Issue: The sensor always reports 'Out of range'.
Solution: Check power supply and wiring. Ensure SHUT pin is pulled high. Try initializing with a different I²C address if using multiple sensors.
Issue: Device does not show up on I²C scanner.
Solution: Double-check SDA/SCL connections and use pull-up resistors (~4.7kΩ) if necessary. Ensure address conflicts are avoided if multiple devices share the bus.
Issue: Readings fluctuate rapidly.
Solution: Use averaging in code, reduce ambient IR noise (sunlight), and avoid glossy targets.
Debugging Tips
Use the Serial Monitor to check for error messages and verify the sensor's output. Add debug prints in your code to track the sensor's state.
Use a multimeter to verify voltage levels and check for continuity in your connections. Ensure the power supply is stable and within the sensor's requirements.
