Description

This is a high-performance microwave sensor designed based on the principle of Doppler radar, using advanced 24GHz communication frequency band and stable and reliable data transmission through RS485. It is designed specifically for intelligent scenarios that require precise human motion detection, such as hotel guest control, smart homes, building automation, and security systems. With its excellent stability, powerful penetration capabilities, and flexible configurability, it has become an ideal upgrade alternative to traditional infrared sensors.

Detailed introduction

1. Advanced technology: 24GHz microwave induction, intelligent interference free

Principle advantages:AdoptingDoppler Radar Principal It can detect the smallest human movements with extremely high sensitivity, effectively reducing false negatives.
Frequency advantages:

operates in the dedicated 24GHz frequency band, effectively avoiding common wireless signal interference such as Wi Fi (2.4GHz/5GHz), ensuring stable performance in complex wireless environments and fearlessness of harsh electromagnetic environments.ofStrong penetrability:Compared to traditional infrared induction, microwave induction hasPowerful penetration abilityIt can penetrate non-metallic materials such as glass and acrylic. This means that the sensor can be hidden and installed inside the ceiling or behind decorative panels, achieving "invisible" intelligent sensing without affecting indoor aesthetics.

2. Excellent Performance: High Stability and Reliability

  • High Quality Process:AdoptingSMT SMT SMT processBy optimizing circuit design and using high-quality electronic components, the consistency, stability, and long lifespan of the product's internal quality are ensured.
  • High protection level:HavingIP20 protection levelMeet the daily indoor installation requirements.
  • Wide environmental adaptability:Wide working temperature range (-30℃ ~ +50℃) It can adapt to complex environments such as high and low temperatures, humidity, strong dark light, strong winds, airflow, and noise, ensuring stable operation under various working conditions.

3. Flexible configuration: powerful customizable features

  • RS485 data transmission:Adopting industrial standardsRS485 serial communicationThe signal transmission distance is long (8-10 meters), with strong anti-interference ability and low power consumption, making it particularly suitable for building large-scale intelligent control systems in networking.
  • Adjustable ID Address:The default ID for the product at the factory is 1. When multiple sensors need to work together, a simple setup process (long press the ID key for 3 seconds, send instructions through the 485 serial port) can be used to set a unique ID for each sensor, making it easy to achieve partition control and precise management. It can support up to 64 or moresensorsNode networking.
  • LED indicator light controllable:The LED indicator lights on the device can be set to "on" or "off" as needed. Turn it on during installation and debugging for easy observation of the status, and turn it off after formal use to avoid light interference, especially suitable for light sensitive environments such as bedrooms.

4. Easy installation: professionally designed and widely applicable

  • Suggestions for ceiling installation:Recommended for ceiling installation, with the antenna sensing surface facing vertically downwards, the optimal installation height is2.5 meters to 5 metersbetween.
  • Wide detection range:The farthest detection distance can reach8 metersThe detection angle is150°(Microwave angle), can effectively cover a large area.
  • Wide applicability:Widely used inHotel intelligent guest control(When people come, the lights turn on; when people leave, the lights turn off)smart home(Automatic scene triggering)Building automation(Energy saving control) andsecurity system(Dynamic monitoring) and other fields.

5. Integrity and Pragmatism: Quality is Clear at a Glance

  • Real Photography Display:The product promotional pictures are all taken from real objects, adhering to the principle of "no fraud", allowing customers to have a direct and authentic understanding of the product's appearance and internal workmanship.
  • Certificate Complete:The product has relevant certifications, guaranteed quality, and can accept OEM/ODM customization to meet the personalized needs of different customers.
