Critical Flaws of Traditional Infrared Sensor Faucets
In high-end bathroom applications, basin faucets with spouts positioned just 15–25 cm above the bowl bottom face constant high humidity and frequent splashing, causing traditional infrared solutions to fail repeatedly.
|
X
No water flow — sensor window covered by dirtMineral deposits and soap residue on the sensor window attenuate the infrared signal, preventing water activation when hands are placed under the faucet. In kitchen environments, grease and dishwashing liquid are particularly detrimental to infrared sensing performance. |
!
Water Not Shut Off — Mist Refraction Triggers False SignalWater mist condensation refracts infrared signals, causing false triggers that keep the faucet running even after hands are removed—wasting water and risking overflow when no one is present. |
|
R
Basin Reflective InterferenceReflections from the basin at the spout mounting position, the pop-up waste, and the water column itself can cause frequent false triggers of the infrared sensor. This interference is particularly severe with white or mirror-finish basins. |
C
Corrosion from Chemical ResiduesFrequent contact with chemical residues from facial cleansers and hand soaps reduces the transparency of the infrared sensor window, leading to gradual degradation of sensing performance over prolonged use and higher maintenance costs. |
dTOF Laser Sensing: Six Core Technology Breakthroughs
Material-agnostic, color-tolerant: sensor distance variance under 10 mm across black, white, and gray finishes; precise detection on stainless steel, ceramic, mirror, and glass surfaces; hand detection range consistent within 10 mm regardless of skin tone.
|
01
dTOF Laser Precision Distance MeasurementDirect time-of-flight measurement principle with 940 nm infrared laser pulses and nanosecond-level ranging. ±0.5 cm accuracy ensures precise hand-distance detection, eliminating false triggers or delayed shut-off caused by distance misjudgment. |
02
Penetrating Water Mist for Stain ResistanceLaser narrow-beam and time-of-flight technology ensures a ranging deviation of less than 1 cm even within a 0.5 mm water film window. Residues such as toothpaste, oil films, or flour do not affect sensing performance. |
03
Compact Concealed DesignControl board diameter ≤20 mm, height ≤12 mm; directly embedded within the standard faucet body. Faucet manufacturers can integrate dTOF sensing functionality without modifying existing molds. |
|
04
Dual-Chip Interchangeable PlatformDual-supplier interchangeability allows compatible chip swaps without PCB modification, mitigating supply chain risks. This provides critical production assurance for ODM customers amid global semiconductor volatility. |
05
Ultra-Low Power Consumption + Rechargeable Lithium BatteryStandby current of 20 µA; battery-powered models last 12–18 months. The lithium-ion version charges via USB Type-C in 1.5 hours and delivers up to 9 months of use, ensuring zero-consumable maintenance for kitchen applications. |
06
Adaptive Sensor Range CalibrationAfter installation, the system automatically detects basin-bottom distance, background reflectivity, and mounting height to set optimal sensor parameters. No manual potentiometer adjustment is required, reducing installation and commissioning complexity. |
