AT S58-4020 5.8GHz Motion sensor
Version 1.1 6
7. Light-dependent detection
According to the Figure 1, there is no daylight sensor by default, an additional light sensor is
needed to have build-in dusk to dawn sensor, in that case, updating software is also necessary.
8. 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.
