IoT entry-level example based on MQTT message communication: GD32E231+ESP8266 implements Wi-Fi remote temperature and humidity collection, control and network clock

This solution is based on the GD32E231 Cortex-M23 core MCU as the main control. The Wi-Fi module uses Essence's ESP8266 and is developed for secondary use. The LCD screen using the SPI interface displays relevant information. The peripheral circuit part uses simple LED lights. Buttons and sensors to complete the demonstration function with the MQTT server.

Building construction monitoring and security system

Whether during construction or in use, civil construction projects require real-time health monitoring of the building structure, such as inclination changes, wall subsidence displacement, support pressure, concrete solidification temperature...

Traditional monitoring methods generally use on-site Wiring, manual scheduled patrols, and on-site reading with handheld instruments, the use of IoT technology is seriously insufficient. Therefore, this project will use LoRa networking and IoT technology to implement wireless and automated building monitoring applications.

Open source power meter: with power supply function, dedicated to IoT power consumption measurement

The biggest feature of testing the power consumption of IoT devices is the high dynamic range, a few uA in the sleep state and hundreds of mA in the transmitting state, and it supports dynamic switching of the measurement range. The open source power meter ZS1100A has a dynamic measurement range of 1uA to 1.5A, a resolution of 100nA, and an accuracy of 1% ± 200 nA, which is very good.

Sony's super powerful IoT kit based on its own CXD5602 (open source information)

The biggest highlight of this kit is Sony's own 6-core microcontroller CXD5602, which comes with 1.5MB of general-purpose SRAM, 64KB of backup SRAM, and a main frequency of 156MHz. There is also an M0+ core assist processor for IO control management, which comes with 256KB of general-purpose SRAM. The built-in GNSS receiver supports GPS and GLONASS. Others include 2D graphics acceleration (supporting rotation, scaling, mixing, etc.); dedicated sensor acquisition peripherals (with its own 40KB FIFO and supporting preprocessing) supporting SPI, I2C and other interface methods; DCMI camera interface and I2S audio peripherals All pretty good too.

Remote home appliance controller based on Raspberry Pi and web interface

A project that uses a web page to remotely control the Raspberry Pi to send out infrared signals to control home appliances such as air conditioners. To put it simply, you can use your mobile phone to control it through the web page on the way home, turn on the air conditioner in advance, and set it to the required temperature. At the same time, the indoor temperature and humidity can be monitored in real time on the web page. The entire project is written based on Python's flask framework.
