LED radar sensing clock, with a built-in high-sensitivity radar module powered on, the LED screen defaults to an off screen state. The module emits a fan-shaped sensing wave of about 130 ° to the front, which is reflected to the radar module when it detects a person's movement or significant movements, thereby turning on the LED screen. When the person stops moving or leaves the sensor, the LED screen will turn off within 3 minutes. The module is equipped with a built-in light sensor, which reduces the brightness of the LED screen display by half when the light is weak, thus adapting to
Sensory and visual perception of characters, intelligent and environmentally friendly.
Operating instructions:
SET key: Short press the SET key to enter the settings. The first flashing number represents the year setting,
Press the UP key to adjust the value, then press SET to confirm and proceed to the next setting item.
The setting order is year month day time minute alarm clock hour minute alarm switch, and the week is automatically adjusted;
Alarm clock off display - the alarm clock on display is ON and the alarm clock symbol is displayed;
The alarm clock goes off for 1 minute and stops ringing. During the ringing process, press any key to stop ringing
UP key: During the setting process, press the UP key to increase the value; Press the UP key to switch to 12/24-hour mode on the normal display interface
EXIT: Press the EXIT key during the setup process to save the current settings and exit the setup state; Press the EXIT key to switch to the normal display interface
Change the temperature display to Fahrenheit/Celsius
Long press the SET button and display ON to turn on the radar function. Turning on the radar function
After three minutes, the screen will turn off;
Press and hold the SET button, and if it displays OFF, it means the radar function is turned off. After turning off the radar function, the display will remain on
matters needing attention:
1. There must be no metal obstruction in front of the sensing surface
2. The module should be as parallel as possible to the installation carrier plane.
3. The module has a positive sensing surface on the component side and a negative sensing surface on the reverse side. The negative induction surface effect is slightly inferior.
4. Microwave modules cannot be applied on a large scale in the same area, otherwise mutual interference may occur, and the distance between individual units may vary
It is best to be greater than 1 meter.
