Product Overview
MODBUS MBS10is adual sensor micro motion detection presence sensor, which can accurately detect the presence of static human bodies in the area - different from ordinary PIR infrared sensors that can only detect moving human bodies, MBS0102 can capture the small movements of the human bodyMinor movements(chest heaving caused by breathing, finger movement during typing, etc.), thereby determining whether there is a person in the area. The detection results are perfectly integrated into the Home Assistant system through dual channel outputs ofdry contacts and RS485 bus.
Traditional PIR vs Dual Sensor Presence Sensor
| Comparison Item | Traditional PIR Infrared | MBS10 dual sensor existence |
|---|---|---|
| detection principle | pyroelectric infrared (moving+temperature difference) | microwave Doppler+micro motion analysis |
| static human body | ❌ Unable to detect (judged as unmanned when the person is stationary) | ✅ Accurate detection (capturing respiratory fluctuations and small movements) |
| Penetration ability | Non penetrable non transparent objects | Can penetrate thin walls, glass, wooden boards |
| High false alarm rate | (sunlight, hot air, pets) | Low (dual authentication cross validation+algorithm filtering) |
| Applicable scenarios | Corridor, entrance | Office, bedroom, study - areas where people sit quietly for long periods of time |
Core application scenarios
- Smart OfficeDetected someone at the workstation → Maintain air conditioning and lighting; Long term unmanned → automatic shutdown
- Elderly careElderly people who remain stationary in a certain position for a long time may fall or feel unwell, triggering an alarm
- hotel roomDetected someone in the room → Maintain power supply; Detected unmanned → Enters energy-saving mode
- Study/AV roomWhen a person sits on the sofa reading a book or watching a movie, traditional PIR will judge it as an unmanned room and automatically turn off the lights. MBS10 does not know
Installation key points
The coordination of installation angle and quantity is crucial - the effective detection area of a single MBS10 is within a conical range, and it is recommended to install 2-3 units in large rooms with cross coverage. The product provides detailed installation and deployment guidelines and Modbus protocol tables.
