[Tuya Smart] Lime Sensor

Overview

The project MCU uses stc8a8k and dht11 to collect temperature and humidity. Tuya WB3s WiFi&BLE dual protocol module is used for wireless transmission. The Tuya platform is used to build the Internet of Things with a 0.96-inch OLED screen to display real-time temperature and humidity. It can also display temperature and humidity on a WiFi host computer. An interface is reserved to expand relays or soil moisture sensors according to actual conditions. Using USB power supply solution, there is no need to replace the battery for a long time. This is my first independent creation and may have many shortcomings. I hope you guys won’t criticize me.

How do transistors drive dot matrix?
Using Protues as shown in the picture, the base can't drive the dot matrix whether there is a level or not. In addition, the transistor can light up the dot matrix without connecting to the power supp
Sine wave oscillator explanation
I am a beginner. I am learning analog electronics. I saw a sine wave oscillator and tried to make one myself. However, the output waveform is as shown in the figure below.I hope the big guys passing b
stm32 stop mode wakeup problem
Help! Now I use stm32 to wake up and use PA8 pin as external interrupt wakeup, but I want to wake up stm32 after the level of PA8 pin is stable. It seems that stm32 does not have such a level-triggere
Phase shift algorithm implemented in DSP
This article is from HELLODSP. I saw a friend asking how to achieve phase shift in DSP. I thought that the software implementation method should be simpler than the hardware implementation, and it can
