How to adjust the sensitivity of radar human sensor switch to improve the response effect of equipment

The radar body sensor switch is a very common electronic device that can detect the motion of the human body and automatically turn the device on and off without touching the switch. Many people have installed the radar body sensing switch, but do not know how to adjust the sensitivity, especially when the sensitivity is not very inconvenient. Therefore, we need some way to adjust the sensitivity of the radar human sensing switch to better suit our needs.

First, what is radar human body induction switch?

Radar human sensor switch is a kind of electronic product which can detect human dynamic and control switch automatically by using radar signal. Unlike general electronic switches, it does not need physical contact, can control the electrical switch on and off. The sensitivity of the radar sensor switch is controlled by the ultrasonic module. According to the ultrasonic return time, it calculates that there is no one near the equipment, and sends the result back to the control module.

Two, the use of radar human body induction switch

Radar human sensor switch is widely used in indoor smart home and security fields, such as burglar alarm, intelligent lighting and air conditioning control. The radar human sensing switch is a very convenient device, which only requires the body to be close to the device to realize the trigger operation, without the need to touch the switch.

3. Method for adjusting sensitivity of radar human body induction switch

Some users have reported that the sensitivity of the radar human sensor switch is not enough in actual use, so it needs to be adjusted to achieve the best effect. So, how to adjust the sensitivity of radar human sensor switch?

1. Adjust the position of the radar module

First, we can try to adjust the position of the radar module. Since radar needs to be transmitted to the human body and reflected back, its range is limited. If the sensor switch is too far away from the human body, the radar reflection signal will be weak, thus affecting the detection range and detection sensitivity of the radar sensor switch. Therefore, we can properly adjust the position of the radar module, so that it is close to the human body, to ensure that the radar is reflected back at the appropriate distance, thus increasing the intensity of the detection signal.

2. Change the radar module Angle

Secondly, we can adjust the Angle of the radar module. If the Angle of the radar module is skewed or even perpendicular to the human body, the detection range and sensitivity will be reduced because the waves will be blocked. We can adjust the Angle of the radar module so that it is properly pointed at the human body, thus increasing the detection range and detection sensitivity.

3. Check the environment around the device

We can examine the environment around the equipment to determine if there are factors that may affect the sensitivity of the radar human sensing switch. For example, there may be environmental noise that affects ultrasonic propagation, or there may be other obstacles, such as doors, decorations, etc. By examining these factors and adjusting the position, we can improve the detection sensitivity of the radar's human sensor switch.

In addition to adjusting the position of the ultrasonic module, changing the Angle of the ultrasonic module and checking the environment around the equipment mentioned above, we can also take the following measures to further improve the sensitivity of the radar human sensor switch:

4. Adjust sensitivity parameters

Some radar body sensing switches have sensitivity adjustment parameters, which can be adjusted in the device itself or the relevant mobile phone APP. If your device supports sensitivity adjustment, you can try increasing its sensitivity appropriately to make it more sensitive.

5. Refer to the product manual

Different types of radar human sensor switch, its adjustment method may be slightly different. Some products may come with instruction manuals, which we can refer to for specific adjustments.

6. Upgrade the device firmware

Some radar human sensing switchgear may have the firmware version is too low, processing speed is slow and other problems. You can try upgrading the device firmware to improve its processing speed and sensitivity.

When adjusting the sensitivity of radar human sensor switch, we should hold the attitude of "patience" and "practice", try different methods and adjust constantly, so as to find our own adjustment method. It should be noted that when adjusting the sensitivity of the radar human sensor switch, we must ensure the safety of the equipment to avoid any accidents.

Iv. Summary

Radar body sensing switch is a very convenient smart home product, but its sensitivity needs to be adjusted according to the actual situation to ensure its best effect. When adjusting the sensitivity of the radar human sensor switch, we can try to adjust the position and Angle of the ultrasonic module, and check whether the surrounding environment will affect the detection sensitivity. These methods can help us adjust the sensitivity of the radar human sensing switch to better meet our needs.

In general, the sensitivity adjustment method of radar human sensor switch is very simple, only need to adjust according to the actual situation. In practice, we need to pay close attention to its sensitivity to ensure that it can quickly and accurately detect human body dynamics and control corresponding electrical switches. If you run into problems, try the above methods or consult a professional for help.

The author hopes that this article can be helpful for readers to understand the sensitivity adjustment method of the radar human body sensor switch, and hopes that more people can understand and use this smart home equipment, and bring more convenience to life.
