Radar industrial human detection sensor ordinary switch how to change the human sensor switch

In modern industry and daily life, the application of human body detection sensors is more and more extensive. Among them, the ordinary switch of radar industrial human detection sensor is a common product. However, sometimes users may need to change it to a human sensing switch. This paper will introduce in detail the modification method and precautions of the general switch of the radar industrial human detection sensor.

First, understand the general switch of radar industrial human detection sensor

Before starting the transformation, we need to understand the basic principle and structure of the common switch of the human detection sensor in the radar industry. The switch usually consists of a radar sensor and a circuit board. Radar sensors can transmit and receive electromagnetic waves, when the human body enters the detection range of radar sensors, electromagnetic waves are reflected back and received by the circuit board. The program on the circuit board determines whether the human body is within the detection range by processing the reflected signal, so as to control the on-off state of the switch.

Second, modify the human body induction switch

After understanding the basic principle of the ordinary switch of the radar industrial human detection sensor, we can start to change it into a human sensor switch. The steps of transformation are as follows:

Find the radar sensors and the circuit board

First, you need to find the location of the radar sensors and circuit boards. Typically, these components will be installed inside or on the bottom of the switch. They can be removed using tools such as a screwdriver.

Buy a body sensor

In the market to buy a human sensor, you can choose different types of sensors according to your needs, such as microwave sensors or infrared sensors.

Connecting circuit

The output signal of the human sensor is connected to the input terminal of the radar sensor, and the output signal of the radar sensor is connected to the input terminal of the circuit board. Then, use wires to connect the output terminals of the circuit board to the appliances that need to be controlled.

debug

After completing the circuit connection, you need to debug. First, turn the appliance on, and then gradually move closer to the radar sensor to observe the reaction of the appliance. If everything is normal, the transformation is successful. If the sensing distance is too far or too close, it needs to be fine-tuned.

Third, precautions

In the renovation, the following points need to be noted:

When buying a human sensor, you need to consider whether its performance parameters meet your needs. For example, sensing distance, reaction time, etc.

When making circuit connections, you need to use the correct wire and ensure that the connection is strong and reliable.

When debugging, it is necessary to gradually approach the radar sensor and observe the reaction of the electrical appliance in order to find the problem and adjust it in time.

When using ordinary switches for human detection sensors in the radar industry, attention should be paid to protecting components such as radar sensors and circuit boards to avoid damage or contamination.

If you need to repair or replace parts, you need to turn off the power and disconnect the circuit to avoid accidents.

In short, it is a relatively simple task to change the ordinary switch of the radar industrial human detection sensor to the human sensing switch. However, it is necessary to pay attention to safety and reliability when carrying out the renovation, and to follow the correct operating steps and precautions.
