Overview:
TQ5529 master-slave clock controller is a brand-new time controller combining satellite timing and LoRa wireless transmission. Satellite timing ensures the controller's time is always accurate; LoRa enables remote time transmission, suitable for distributed networks requiring time synchronization. The TQ5529 also features an LCD screen for status display and on-site manual settings, providing a comprehensive solution for schools, factories, and other places requiring time synchronization.
Features:
1. GPS Time Acquisition and Timekeeping
The TQ5529 can receive GPS satellite signals to obtain standard time; it has a built-in high-stability timing chip to maintain accurate time.
2. Wireless Transmission Settings
It has a test mode and a normal working mode; in test mode, it transmits signals periodically, while in normal working mode, it sends signals at a set time daily.
3. Long-Distance Wireless Communication
It uses LoRa long-distance communication, offering excellent wireless transmission and high anti-interference capabilities.
4. Local Settings and Status Information Display
