1. Introduction In this tutorial, we will use Proteus software to demonstrate how to design and simulate a digital clock thermometer based on the AT89C52 microcontroller. We will cover hardware circuit design, software programming, and simulation testing using Proteus. 2. Project Overview The digital clock thermometer is a device that integrates time display and temperature … Read more
First, buy a Bluetooth module and download a Bluetooth serial debugging assistant on your phone, which is equivalent to the UART serial communication of the microcontroller. Use BUFF to obtain the received data. Here, we only need to focus on one issue, which is testing the encoding. If the APP sends 0xFF, (the APP Bluetooth … Read more

Summary: Recently, it has been snowing in many places, including Hunan, Hubei, and Xi’an. Students who raise tropical plants and pets need to pay more attention to the indoor temperature. Below is a practical and easy-to-make thermometer. It is built using the DS18B20 temperature sensor and OLED module, with the development board being Arduino. The … Read more
The types of temperature sensors are numerous, classified by measurement methods into contact and non-contact types, by sensor materials into thermistors and thermocouples, and by working principles into analog and digital types. The previous article introduced the analog temperature sensor LM35, while this article introduces the use of the digital temperature sensor DS18B20. 1. Introduction … Read more
Temperature is a physical quantity that we often encounter and can intuitively feel, such as needing to add clothing when the weather gets cooler or blowing on food that is too hot. It is also necessary to measure temperature accurately, for example, the normal body temperature of humans is 37.5℃, and the boiling point of … Read more
