IoT application project overview

The auditorium of a comprehensive building of a university has original lighting, including 6 tri-color panel lights for the top light and 14 stage lights for the surface light. With the passage of time, the brightness and color temperature of the top light have decreased or weakened, which can no longer meet the basic needs of conference speeches and small cultural and artistic activities.

A film and television fill light factory in Shantou City, Guangdong Province received this project. Considering that the light will always weaken over time, in order to fundamentally solve the problem, it is necessary to adjust the brightness and color temperature of the light in real time and quickly. The way. Therefore, this film and television fill light factory plans to develop a remote-controlled red, blue, far-red, and ultraviolet four-color integrated high-power LED fill light for this project, including LED fill light and a handheld remote control, so as to realize real-time adjustment of light brightness and color temperature.

IoT application solutions:

LED fill light includes switching power supply, LED light source controller, heat dissipation fins, housing, aluminum substrate and LEDs arranged in two rings with the center of the aluminum substrate as the center, each LED is equipped with a condenser lens.

The handheld remote control includes a battery pack, a control signal processor, function keys, an LCD display and an RF transmitter module;

When the handheld remote control sends an instruction through the RF transmitting module, the LED fill light receives the instruction through the RF receiving module and transmits it to the microprocessor. The microprocessor controls the constant current drive circuit according to the instruction, and then controls the LED, while the LCD The display shows the status mode information in real time. Through RF remote control technology, this fill light realizes the wireless remote control of LED fill light very conveniently. It has the advantages of low power consumption, long transmission distance, high communication rate, stronger anti-interference and higher stability.

The system can also realize the data return function. After the microprocessor B of the fill light controls the light source controller according to the instructions, the processed information is sent back to the E01C-A module through the E01C-B module, and the E01C-A module transmits the processed information back to the E01C-A module. To the microprocessor A, the microprocessor A can display the effect of the operation on the display screen of the remote control, so as to complete the wireless adjustment of the entire light.

Ebyte wireless communication related products:

The E01-ML01S RF module used in the case has the following characteristics:

Long transmission distance: using a low-power (7dBm) module, the transmission distance can reach 300m, using a 20dBm module, the maximum distance can reach 2500m, which can meet most remote control needs;

Low power consumption: The receiving current is as low as 15mA, which can meet the low power consumption requirements of toys.

More cost-effective: E01C series products are more cost-effective and stable in supply, especially at the moment, there is no worry of tight material supply;

Low cost: low cost to achieve stable toy remote control;

Customizable: According to the actual needs of customers, specific functions can be customized and developed;

Support multi-channel communication, 125 communication channels, meet the application requirements of multi-point communication, grouping, frequency hopping and so on;

Different airspeeds can be configured according to requirements: high airspeed, fast transmission, short transmission distance; low airspeed, slow transmission, long transmission distance;

Small size, easier to integrate;

Frequency band license-free: support global license-free frequency band: ISM 2.4GMHz;


Summary of IoT application solutions:

Ebyte's E01-ML01S module successfully solved the problem of light intensity data transmission in the auditorium of the university complex; in fact, there are many RF modules that can be applied to this solution, including WiFi module, Bluetooth module, ZigBee module, 4G dtu, Ebyte has also been committed to the development of smart industry, smart home, smart security, smart transportation, smart environmental protection, smart agriculture and other technical product series such as NB-IoT modules.
