Common Causes
- The sensor sensitivity does not match the environment
- There are interference sources such as air conditioner outlets, glass reflections, or moving indoor plants
- The sensing area is blocked or misaligned in angle
Three-Step Solution Path
Step 1: Prioritize Diagnosis
Use a blocking board to eliminate interference sources one by one, avoiding blindly replacing the sensor. About 70% of problems can be solved at this step.
Step 2: Switch Mode
Change the sensor from "single microwave" or "single infrared" to "microwave-infrared composite mode," which can reduce false triggers by more than 80%.
Step 3: Dynamic Calibration
In an unoccupied state, use the adjustment terminal or app to adjust the sensing distance and hold time, allowing the door system to adapt to the on-site pedestrian flow rhythm.
Real Case
An automatic door in a mall used to trigger falsely more than 40 times per hour. After the adjustments above, it dropped to fewer than 2 times, with energy consumption reduced by 18%.
First check the environment, then adjust parameters, and finally work on the hardware — most automatic door sensing issues can be resolved without replacing parts.
