This project covers all the necessary steps in developing a universal temperature sensor! Keep reading to see all the various applications! My partner, Asha, and myself, Sam, have developed an innovative, accurate, and universal way to measure temperature.
To start this project, we needed to decide what components were required to accomplish our goal. We are utilizing a Particle Argon, an NTC Thermistor, an I2C LCD display, and a few wires to construct this project. We are using a Particle Argon because it is very small in size, has multiple pins for different applications, and most importantly, it can connect to WiFi. WiFi connection is crucial in our project so we can track data as the temperature changes and find trends.
The NTC Thermistor is a great choice for our project because it has a wide range of temperature values it can read. The thermistor is extremely sensitive, making it easy to read various temperatures. It can detect temperatures anywhere from -67 Degrees Fahrenheit to 450 Degrees Fahrenheit.
We connected the Particle argon to the NTC Thermistor and the LCD display. The schematic shown below is also attached at the bottom of this page for downloads.
As we constructed our circuit, we added a few more things to satisfy the specifications of each component. The thermistor is connected to a 10k Ohm resistor to regulate power.
The next step was to collect live data from our thermistor. We used ThingSpeak to display our data in a graph. This tool was easy to use and compatible with our IOT device.
Now that we have everything constructed, we are able to record the temperature data from the room, an appliance, an engine, virtually anything! Share in the comments what YOU could use this device for!
