Automatic door sensor calibration is a key step to ensure the normal operation of the automatic door. According to the search results, the following are the main methods for automatic door sensor calibration:
1. Adjust the detection range of the sensor
- Method: Adjusting the detection range of the sensor is the key to adjusting the sensitivity of the automatic sensing door. Generally speaking, the larger the detection range of the sensor, the higher the sensitivity of the automatic sensing door. However, if the detection range is too large, it will cause the door to malfunction. Therefore, the detection range of the sensor needs to be adjusted according to the actual situation.
- Steps:
1. Find the adjustment knob or button on the sensor.
2. Turn the knob clockwise or counterclockwise to increase or decrease the detection range.
3. Test the reaction of the door to ensure that it can sense normally within the appropriate distance.
2. Adjust the sensitivity of the sensor
- Method: Determine the sensitivity by adjusting the threshold of the MCU digital-to-analog conversion. The location of the sensor varies for different versions, but there is usually a blue sensitivity adjustment knob on the lower left corner of the sensor circuit board.
- Steps:
1. Open the sensor housing and find the sensitivity adjustment knob.
2. Turn the knob clockwise or counterclockwise to increase or decrease the sensitivity.
3. Test the door's response to ensure that it can sense normally at the appropriate sensitivity.
3. Adjust the angle of the microwave module
- Method: By adjusting the pitch and horizontal angle of the microwave module, you can adjust the sensor's action area.
- Steps:
1. Loosen the screws that fix the microwave module.
2. Adjust the pitch and horizontal angle of the module so that the sensing range covers the required area.
3. Fix the screws and test the door's response.
4. Adjust the door's opening and closing mechanism
- Method: When the sensor detects a person, the door's opening and closing mechanism needs to be triggered. If the door's opening and closing mechanism is not sensitive, it will cause the door to open and close delayed or unable to open and close. Therefore, the door's opening and closing mechanism needs to be adjusted.
- Steps:
1. Find the adjustment knob or button on the access control device.
2. Turn the knob clockwise or counterclockwise to increase or decrease the sensitivity of the opening and closing mechanism.
3. Test the door's opening and closing action to ensure that it can be opened and closed normally.
5. Regular maintenance and cleaning
- Method: Keep the sensor and door frame clean to prevent dust and debris from affecting the normal operation of the sensor.
- Steps:
1. Wipe the sensor and door frame with a clean cloth.
2. Clean the debris around the door machine to ensure that there are no obstacles to the sensor.
3. Check the working status of the sensor regularly and replace damaged parts in time.
The above calibration method can effectively ensure the normal operation of the automatic door sensor and avoid the problem of the door not being able to open or close normally due to sensor failure.
