4 Best DIY Temperature Sensors Tutorials DIY Temperature Sensor This is a very simple DIY temperature sensor. You can use it to measure the temperature of your room, house, greenhouse etc. It is based on the LM35 series analog temperature sensor from Texas Instruments. The original version of this project was designed by David Johnson-Davies. This article shows how to build and program a slightly more advanced version of this circuit. The main difference is that the Arduino receives commands from the computer and returns values back to the computer. This allows us to monitor and record temperature changes in real time. Build Your Own Temperature Sensor Have you ever wanted to keep a close eye on the temperature of your home, or office? I recently found myself searching for a good solution to monitor my server room's temperature. It needed to not only have an easy way to access the data, but also be able to send me an alert if the temperature was outside of my specified range. The solution I came up with is a Raspberry Pi with a DHT22 sensor connected to it. The Pi is a small single-board computer that runs Linux. It has 40 GPIO pins to connect sensors and other devices, and it can run several different programming languages, such as Python and C++. One of the best parts about using a Pi is that it has built-in Wi-Fi and Ethernet capabilities, which allow you to easily access your project from anywhere! Thermistor Temperature Sensor Tutorial The thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. There are two main types of thermistors: Negative Temperature Coefficient (NTC) thermistors: The resistance decreases with increasing temperature. These are most often used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements. Positive Temperature Coefficient (PTC) thermistors: The resistance increases with increasing temperature. These are used mainly as resettable fuses and self-regulating heating elements. DIY Arduino Projects Arduino projects can be difficult to know where to start. The huge amount of variety on offer can be seriously intimidating. A good place to start is by getting an Arduino starter kit which contains all the pieces you need (minus any tools) for your first project. The great thing about Arduino, is once you've got the hang of it, you can use it over and over again for different projects. You don't have to buy a new board every time. You just need to change some components and reuse the same board. So how do you decide what project to try first? Well we've scoured the web and found our top ten best beginner Arduino projects that are perfect for self-starters, tinkerers and beginners alike.https://www.sinofudetec.com/gummy-machine/
