ATS58-1818 5.8GHz Motion sensor

Version 1.1

8.Light-dependent detection

According to the Figure 1, there exists light sensor by default and the SDK also enable this

function. If light-dependent detection are not necessary, disable on SDK or remove the light sensor.

9.Installation Notes

 Antenna is sensitive to metal, don't put anything with metal in front of the antenna, thin plastic

and glass is acceptable, however, don't let the antenna cling to the cover, the gap between the

antenna and the cover should be more than 2mm;

 Try to set the antennas in parallel to each other when there are multi radar sensors in the same

space, make sure the gap between two sensors is more than 1m;

 Power frequency may cause serious interference for radar signal, try to put LED driver far

away from the antenna, don't fix the LED driver in front of the antenna;

 Power consumption for the sensor is about 35mA, make sure the current-driving capability

for LED driver is better than 50mA.
