System Composition
Working Principle
Standby Mode: When there is no motion detected by the motion sensor, the system is in standby mode. In this mode, the control circuit monitors the battery voltage and the status of the motion sensor. The power consumption of the system is very low to save battery power.
Trigger Mode: When the motion sensor detects motion, it sends a signal to the control circuit. The control circuit then activates the DC - DC converter to output 80W of DC power to drive the load, such as a light or a fan. The system remains in the triggered state for a certain period of time, which can be set according to specific needs, usually ranging from several seconds to several minutes. After this period, if no further motion is detected, the system returns to standby mode.
Advantages
Energy - saving: The system only consumes power when motion is detected, which can effectively save energy compared to continuous - operation systems. This is especially suitable for applications where the load does not need to be constantly powered, such as some public - area lighting or ventilation systems.
High Reliability: LiFePO₄ batteries have good safety and stability, and the motion sensor and control circuit are also designed to be reliable. The entire system has a low failure rate and can work stably for a long time.
Flexible Application: The system can be easily installed and configured in different environments. It can be used for lighting control in corridors, stairwells, parking lots, and other places, as well as for powering some small - power equipment that needs to be triggered by motion.
Considerations
Battery Capacity and Charging: The capacity of the LiFePO₄ battery should be selected according to the expected working time and the frequency of motion detection. It is necessary to ensure that the battery can provide sufficient power to meet the needs of the system. At the same time, a reasonable charging method should be adopted to ensure the normal use and service life of the battery.
Sensor Sensitivity and Range: The sensitivity and detection range of the motion sensor need to be adjusted according to the specific application environment. If the sensor is too sensitive, it may cause false triggering; if it is not sensitive enough, it may fail to detect motion. Therefore, it is necessary to conduct field tests and adjustments to ensure the proper operation of the sensor.
Load Compatibility: When selecting a load, it is necessary to ensure that the load is compatible with the 80W DC output of the system. The rated voltage, current, and power of the load should match the output characteristics of the system to avoid damage to the load or the system.
