Power Supply Recommendations
For optimal performance, it is highly recommended to utilize a qualified DC stabilized power supply that adheres to standard specifications for output voltage, current, and ripple coefficient. Failure to meet these requirements may compromise the stability of the product, potentially resulting in issues such as false alarms, lack of induction, or cyclic self-start.
Prevention of False Positives
Power Supply Verification: Ensure the power supply meets the necessary qualifications as outlined above.
Environment Preparation: During testing, ensure that there are no moving objects present within the sensing range to avoid interference.
Initialization Time: Allow for a 5-second initialization period after powering on to prevent abnormal inductions that could trigger false alarms.
Indoor Testing Protocol: Maintain a static environment during sensitive sensing and wait for the completion of the first sensing signal cycle before proceeding with the next test.
Outdoor Testing Considerations: Pay close attention to dynamic environmental factors such as birds, pedestrians, and vehicles during outdoor testing.
Load Connection: The module's weak signal current may lead to false alarms when directly driving the load. Refer to the product's application diagram for proper connection guidelines.
Working Delay Adjustment
To modify the delay time, a TIME resistor is soldered on the front of the module. Contact relevant personnel if VR adjustment is not required.
Sensing Distance Adjustment
To alter the inductive distance, a SENS resistor is located on the front of the module. Contact relevant personnel if VR adjustment is unnecessary.
Product Shell Assembly
Avoid installing the product in a metal shell, as metal can impede microwave and infrared penetration. Materials such as plastic, ceramic, and wood offer better penetration. Refer to the testing procedures for detailed instructions.
Product Harmony
Within the effective sensing range, be mindful of potential mutual resonance interference. To prevent any negative impact on performance, avoid installing multiple modules facing each other. Contact our staff for assistance if needed.
