Solar Energy, refers to the heat radiation energy of the sun (see three ways to communicate in thermal energy: radiation), mainly to say the sun rays. It is generally used as power generation or provides energy for water heaters. Since the birth of life on the earth, the heat radiation provided by the sun can survive, and since ancient humans also understand the sun-dried objects, and as a method of making food, such as salt and salt fish. In the case where fossil fuel is decreasing, solar energy has become an important part of human use energy, and it has been continuously developed. Solar energy uses optical heat conversion and photoelectric conversion, solar power is an emerging renewable energy.

3, solar street light wireless controller
systems mannual:
1. After the device is powered on, in the initial 1 minute, in the configurable frequency band, this time the system detects whether there is configuration data from the master. If there is, save the latest control
Data and override the previous control data, if not, read the default data into the working mode;
2. Each device has a unique ID, after the device enters the working mode, automatically connect to the corresponding controller according to the ID device;
3. After 1 minute of the device, it is not connected to the corresponding master for 10 consecutive times, and immediately switch to the optical control mode, and configured data according to the default configuration, or the main controller
Successful configuration data work. Then send the request to connect the master information at intervals for 10 minutes. Until connected to the master.
4. In the case where the device is connected to the main controller, if the control command is accepted, immediately follow the control commands of the controller. If you accept the main controller
The inquiry command is immediately reported immediately. The device fixed interval 30 minutes sends its own status data to the main controller.
5. If the battery voltage is detected is too low, the device automatically shuts down the data. Cut off peripheral drive power, CPU enters low power mode, and drive indicator alarm, 10 minutes from time
Send battery abnormal status data to the master.
6. If the luminaire is detected, the lighting abnormal data is transmitted to the central controller. (Since the battery voltage is pulled out, the battery voltage can be detected in the case of the luminaire.
Detecting whether the lamp is opened. Procedures process: 1 minute before opening the luminaire, detect the battery voltage value V1, the battery voltage is lowered after turning on the luminaire, then V1
As a reference value, then turn on the luminaire, the comparison of the battery voltage is recorded as V2, V1 and V2 can analyze if the lamp is at work). The abnormality here is mainly to refer to an exception.

Sony SPRESENSE development system with integrated GPS and 5 million pixel cameras seems to be ideal for portable monitoring systems. My idea is to build a solar cloud camera unit that captures images with location information. It will have a small color LCD display that helps initial settings by previewing the camera image and overwriting GPS status and location information. It also includes a PIR motion sensor to trigger image acquisition. One of the lack of Sony systems is radio communication (BLE or WIFI). In order to solve this problem, I am adding an ESP8266-01 WiFi module.

8, STM32F0 design more fast charge agreement solar charge treasure (schematic)
Have you encountered a mobile phone without electricity during a travel, the camera is dead, the Bluetooth headset is dead. Even before traveling, it is ready to charge the treasure, but sometimes meet the "eating" speed of the mobile phone. At this time, why not consider buying a solar charging treasure, often heard such a slogan "there is a light", it sounds very beautiful, but now it is still difficult to see the solar charging treasure on the street.
In order to solve the above problems and satisfy my DIY hobbies, use a shared bicycle solar panel to make a solar charging treasure. It has MPPT solar maximum power point tracking function, and the boost circuit uses IP2161 for fast charge protocol identification and match, which can support multiple fast charge protocols. Not much, look at the results of the project below.
