TOF Module vs. IR Module - What's the Difference?
In smart sanitary ware and automation systems, sensors play a key role. The two main sensing technologies are IR (Infrared) and TOF (Time of Flight).
Here's how they differ and why TOF is becoming the new standard.
What is a TOF Sensor?
TOF sensors measure the time light takes to travel to and from an object, accurately calculating distance.
This enables precise, stable detection, even under strong light or reflective surfaces.
Features:
Accurate distance measurement
Fast and stable response
Unaffected by lighting or color
Ideal for advanced intelligent systems
Common Uses:
Smart toilet seats, sensor faucets, high-end urinals, smart mirrors
What is an IR Sensor?
IR sensors detect the presence of an object by receiving reflected infrared light.
When an object enters the sensing range, the reflected light triggers the system.
Features:
Low cost and simple design
Detects object presence only
Easily affected by ambient light or surface reflection
Common Uses:
Basic urinal sensors, simple faucets, touchless switches
Comparison: TOF vs. IR
| Item | IR Sensor | TOF Sensor |
|---|---|---|
| Principle | Infrared reflection | Time of flight distance |
| Detection | Presence only | Precise distance |
| Light Interference | Easily affected | Not affected |
| Stability | Moderate | High |
| Cost | Lower | Slightly higher |
| Application | Basic models | Smart / premium models |
