Environmental expert’s smart watch

The work is mainly based on smart watches as a product that contributes to mine operations. The shape of [RSL10-SENSE-GEVK] is perfect for making a watch. All the onboard peripherals are utilized. The watch will collect data every once in a while and store it in the onboard external Flash. A total of fourteen days of historical data can be stored. If the power consumption is reasonably designed, it can Replace the button battery every two months. Normally worn in the normal mode, you can enter the downhole mode by pressing the button. In the downhole mode, the surrounding environment will be detected. When the environment reaches a bad situation, it will enter the alarm state. At the same time, when the person going down the pit feels uncomfortable, he can long press the button to enter the call for help state.

Electronic door guarding (knock detection, reminder)

The acceleration sensing unit (RSL10+KX023) attached to the back of the door is used to detect vibration and movement to detect events such as opening the door and knocking on the door. It also interacts with the terminal through information through BLE and can view the log on the handheld terminal. Handheld terminals are also implemented with RSL10. After powering on, it automatically scans the target device and connects to it. After connecting, it obtains the time and date information of the device (which can be modified at this time), and then enters the log interface. The wireless sensing unit and the BLE terminal exchange information through the BLE connection.

Smart IoT student dormitory based on RSL10

In view of the characteristics of students' dormitory life, an IoT smart dormitory system is built using ON Semiconductor's RSL10 low-power Bluetooth chip to implement several functional nodes, and a very convenient WeChat applet is used on the control end to monitor data. Through the functional units composed of RSL10 boards for data collection or action control, and realizing the monitoring function of WeChat applet, this project is a simple intelligent control solution for student dormitories, which can be used as courses/graduation projects for students in related majors. Or a case study of ON Semiconductor University planned courseware.

Lazy self-care fish tank control system

The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!

short-term weather forecast system

The author is located in an area with a lot of convective weather and hot and humid weather. I stared at it silently, and saw that the clothes to be dried came in and out five or six times a day... Weather forecast on the mobile app? Weather warning text message? It can only be regarded as a late report. I am lazy, do it myself, have enough food and clothing...
