Smart Sensor

This model M-518TW, TUYA smart home sensor for garage door, is also used for garage automatic gate, or courtyard gate as induction open function, also can be controlled by mobile TUYA APP through Wi-Fi connection.
Both are used for automatic doors to automatically open when receiving a signal within a certain range. After the smart vehicle tag and the receiver are paired by learning bottom, please install the receiver on the automatic door operator controller, and insert the smart vehicle tag into the USB interface of the car.
Use instructions

(1) The car drives to the automatic door
a. The car has not reached the response distance range, the automatic door will not open;
b. The car has entered within the response distance, the automatic door opens automatically.
(2) The car leaves the automatic door
c. The car is not out of the response distance range, the automatic door is still open;
d. The car is out of the response distance, the automatic door closes automatically.
(3) The response distance can be set as 1,2,3,4,5,6 gears on the vehicle tag: Level 1: 1m, Level 2: 2m, Level 3: 3m, Level 4: 5m, Level 5: 8m, Level 6: 10m

LED indicator & Wiring
The red indicator will always on when standby mode;
The blue indicator will always on when received the vehicle tag's signal;
The blue indicator will flashes when learned the tag ID.

Wiring terminal definition and diagram as above.
After the receiver received the paired vehicle tag signal, will output door opening signal; When signal is disconnected, delay 1s output door closing signal for 1s, then according to the delay time setting, to output door closing signal once again.
