Smart lighting is a common application in smart homes, which can achieve energy saving and power saving and provide higher comfort and convenience. Intelligent lighting refers to a distributed lighting control system composed of technologies such as Internet of Things technology, wired/wireless communication technology, power carrier communication technology, embedded computer intelligent information processing, and energy-saving control to realize intelligent control of lighting equipment .
Bluetooth smart lighting
Support scenarios:
Point-to-point remote control smart lights;
The solution uses standard Bluetooth protocol to realize the dimming and color adjustment of LED lights on the low-cost solution of Giant Micro.
Alternative chip models: MS1793, MS1591.
Point-to-group or multiple groups of remote smart lights (MG-Mesh);
This solution adopts Juwei's innovative MG-Mesh system architecture to realize LED self-organizing network and dimming color at the lowest cost. Both mobile phone and remote control can be controlled.
Ad hoc network remote control circuit:
4-key remote control: MG117
multi-key remote control: 8-bit MCU+MG127
The control circuit of the lamp node: adopts 8-bit MCU + MG127
The system cost is much lower than other Bluetooth solutions.
Juwei Bluetooth chip MG127 is a low-power, low-cost BLE transceiver, which integrates transmitter, receiver, GFSK modem and BLE baseband processing. The power supply voltage is 1.9~3.6, it can be powered by a button battery (3.0v), with 3uA standby current, 20mA@0dBm continuous transmission, 18mA continuous reception, etc. MG127 is packaged in DFN3x3, and only needs to be matched with a low-cost MCU and a few peripheral passive devices to realize BLE remote control, Bluetooth electronic scales and other applications.
