II. Features
1. Using advanced wireless transceiver technology, signal transmission can be completed without wiring, and the
project is simple and convenient.
2. Using 470MHz frequency band communication, FSK coding technology, strong anti-interference ability, long
transmission distance;
3. With battery low-voltage detection, remind users to replace when the battery is insufficient to maintain the
detector's normal operation.
4. The use of high-sensitivity thermal elements improves the response speed of the temperature detector to
temperature changes.
