Commercial Sensor Faucets

When Should a Component Actually Be Replaced?

Component Replace Only After Battery Voltage/LED status confirms depletion or abnormal power. Sensor Power, connection, lens condition and calibration are verified. Solenoid Supply, filtration, controller output and valve cleanliness are checked. Controller Power source, connectors and sensor input are confirmed. Filter Clean first; replace only when damaged or non-serviceable. Predictive Maintenance

When Should Engineers Consider Capacitance?

Capacitance deserves consideration where a commercial installation repeatedly challenges optical sensing. Because detection does not depend on reflected infrared, environmental lighting and reflective optical paths are fundamentally different concerns. However, capacitance introduces its own requirements.

Which Technology Should You Choose?

Project ConditionReview Direction Metal lavatory or stainless sinkInfrared is generally the safer starting point. Recurring optical/reflection problemsConsider adaptive IR, whole-body sensing or capacitance. Standard public restroomModern adjustable infrared remains highly practical. Highly controlled integrated sink systemCapacitance can be evaluated carefully.

Sensor or Solenoid?

What to Do When a Faucet Turns On by Itself?

1Clean the sensor surface without abrasive chemicals. 2Remove objects, soap bottles and reflective items from the detection zone. 3Check battery voltage or AC power before adjusting electronics. 4Reduce sensing range and retest the empty basin. 5Observe whether the sensor indicates continued detection after hands leave. 6If detection stops but water continues, investigate the valve/solenoid.
