Modbus protocol 24GHz millimeter wave live presence sensor - motion, micro motion, breathing detection+illumination

描述

1. Product Features

This product is an embedded independent installation wireless RS485 communication sensor with functions of mobile, micro motion, and respiratory detection+light intensity sensing data acquisition. It has a built-in MCU serial port and RS485 module for control and data exchange. The product uses a 24. 125GHz millimeter wave presence sensing module, the latest large beam angle bracket antenna technology, and a new software algorithm. The product's feature is to achieve live presence detection and light intensity information access to the RS485 system as a data acquisition unit.1) Using live detection technology, it can accurately detect movement, micro movement, and respiratory signals, achieving true presence detection.

3, Function Description

The product adopts a dual mechanism of reporting and querying, transmitting the human body status information of unmanned/manned and illumination data to the RS485 module through the MCU serial port.Movement:Detected a significant movement (walking) signal of the human body within the detection area.Micro motion:Detected small amplitude motion signals of the human body within the detection area, such as forward leaning, backward leaning, limb swinging, shaking head, typing, playing with mobile phones, and other small amplitude behavioral movements.exists:only detects respiratory vital signs of the human body (abdominal and thoracic dilation behavior), without detecting large movement signals and micro motion signals.Light sensitivity reporting:When the external light changes beyond the set light sensitivity difference, the light sensitivity value command is reported.

1. Set sensitivity, indicator light, and delay function parameters through serial port. When the sensitivity is set to 0%, the sensing of the sensor will be blocked and lose its sensing function.
2. When the sensitivity is set to 0%, the sensor's sensing will be blocked and lose its sensing function.
3. supports human body sensing detection function and light intensity detection function, and sets related conditions for automatic control of other devices.

10, Communication parameter format and protocol

Checksum: 51+FF+FF+06+05+64=2BE Take the last two digits BE

Checksum: 51+FF+FF+08+07+09+27+C0=34E, take the last two 4E digits

Status reporting instructions:

Note: The delay time needs to be set to at least 30 seconds for the detection function to exist! Within 30 seconds, only motion sensing function is available.

 ID Method: After 20 seconds of power on self-test, press the button briefly once to enter the ID programming mode (51 FF FF 06 21 01 77 appears on the serial port). The indicator light will flash rapidly, and the ID can be set within one minute. After success, the indicator light will stop flashing. (After entering, press the button briefly again to exit the programming mode, and the indicator light will stop flashing)ID Default0xFFFF3) Method for restoring factory settings:  Long press the panel button for 3 seconds to restore the factory settings. The device ID will not be restored, and active reporting and passive querying will not be restored.

Note:

1. If there is an error in setting the data range, return: 51XXXX06FF02XX
2. If there is no such function or the command is sent incorrectly, there will be no feedback

Eleventh, Initialization Status

The initial power on indicator light flashes for 20 seconds before turning off. During initialization, no external movement sensing signals are detected. The indicator light can be turned off and on through a serial protocol, and the detection range (sensing distance) can be set through a serial protocol.

Detection Area:100%     Hold Time:1min            Indicator light: open

13, Product application precautions:

1. Sensors should be installed and wired by professional electricians.
2. Sensors should be kept away from large areas of metal plates, glass, and other materials with high dielectric density to avoid triggering errors.
3. Avoid using objects that vibrate for a long time around the sensor, such as shaking fans, as the vibration signal will be considered as a movement signal triggering the sensor.
4. Avoid ineffective light sources illuminating the detection window of the illuminance sensor of the detector, which may interfere with the measurement of ambient light. When installing and using the product, it should not be too close to the wireless router, at least 2 meters apart.
5. When installing and using the product, it should not be too close to the wireless router, at least 2 meters apart.
6. Sensitivity and indicator light switch settings can be set using the MH10 remote control, (HS button indicator light "on" LS button indicator light "off" on the remote control)

7. Microwave sensors have a certain penetration ability through building walls, and when microwaves penetrate outside the walls and act on moving objects outside the fortified area, they may cause false alarms. To avoid accidental triggering, attention should be paid to selecting the installation location and appropriate sensing range during installation, such as:

1. When the product is applied in rooms with a length and width of about 2 meters or less, the sensitivity should be set to 25% (application scenario: bathroom, reception room)
2. When applied in a room with a length and width of about 3 meters, the sensitivity should be set to 50%; (Application scenario: restroom entrance and reception room) C. When applied in a room with a length and width of about 4 meters, the sensitivity should be set to 75%; (Application scenario: Small office, conference room, library)
3. When applied to rooms with a length and width of about 5 meters or larger, the sensitivity should be set to 100%; (Application scenario: Large office, conference room, library)

Note: The specific sensing range for practical applications depends on the actual environment, and a suitable gear should be set. The sensitivity selection settings for the above application scenarios are only for reference.).

8. Delay setting: Single person space: 1-3 minutes, multiplayer space: 30-1 minutes. It is not recommended to set a delay of more than 5 minutes to avoid interference from small motion signals in the space and delay the shutdown time.
9. This product does not come with terminal resistors. Please pay attention to impedance matching when connecting to the bus system.
