5.1 GPRS Wireless Module
GPRS module can be used to communicate with the base stations and help to transfer a variety of
instructions, such as: switching ON/OFF, dimming commands, uploading power consumption data, uploading
illuminance information, etc.
5.2 Control Module
After booting, the module automatically obtains the command sent by the system to start the dimming
strategy. If not set, the module will dim according to the factory default strategy.
5.3 Light sensor (optional)
The light sensor uses a digital light sensor. Its sensing range is adapted to the recognition range of the human
eye. After the module joins the NB network, it will upload the illuminance data to the gateway. When the module
works offline, it will turn on the lights at 16±6 lux and turn off the lights at 50±6 lux (default setting).
5.4 Dimming
The product has 1 channel 0-10V analog dimming interface and one channel PWM interface. To better
accommodate the needs of multiple LED drivers, the default dimming curve is shown in Figure 5.
