In one of the previous instructable, we saw how to make a simple thermometer with ATTINY 85 which can last for 140days with a single battery and it still works great after 40+ days with the same battery I showed in the video. But it was a tiny bit clumsy when it came to the electronics …

This is a project for Arduino to make a Thermometer with Digital Display, aimed at beginners. Arduino measures the voltage on a TMP36 Temperature sensor, converts the Voltage to Degrees Celcius and Displays the value on an LOL shield display. Objectives: * Learn how to use the TMP36 * Learn how to perform numeric and …

Using a dual 7-segment display, a DS18B20 temperature sensor and a couple of shift registers I figured that I could build a digital thermometer. Step 1: Temperature Sensor The sensor I’m using is the DS18B20, it’s a 3pin sensor that just requires a single input pin from the arduino. Multiple sensors can be hooked together, …
The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the microcontroller can use to interface with the real world. If you’re looking to extend the platform’s reach in one of …
Hygrometers are used to determine the moisture content of the environment. They find application in farms, food storage, museums, and other places where moisture needs to be monitored to ensure damage is not done to goods and other things stored in that space. For today’s tutorial, we are going to build a Hygrometer using the …

Currently, we are chasing an invisible monster named Corona Virus ( COVID-19 ) and we are going through the biggest health crisis in our time due to a sharp increase in infection cases. One of the main symptoms of the COVID-19 infected person is an increase in body temperature, in addition to other symptoms such as pain …
This might seem totally useless, considering how advance current technology can be and you might even be like “Tsk! a Thermometer?” But there is a lot of experiment based on temperature (water temperature, room temperature, etc) so digital thermometer becomes a key instrument for temperature measurement considering the other alternatives and cost/performance ratio. It is …

Don’t blame us for the title. [CCrome] admits it may well be the cheapest and worst IR camera available. The concept is surprisingly simple. Mount a cheap Harbor Freight non-contact thermometer on a 3D printer carriage and use it to scan the target. The design files are available on GitHub. There is, of course, an Arduino to grab …
WORLD’S CHEAPEST AND POSSIBLY WORST IR CAMERA Continue Reading
A lot of people know that temperature is the degree of heat present in a substance. The common way of measuring body temperature is the armpit method where temperature is measured by putting the thermometer under the armpit. However, there are better ways of measuring this temperature. Right now, the most accurate temperature measure is …

It seems that you can’t visit to a microcontroller website without seeing a digital thermometer/hygrometer build of some kind. After all, it is pretty easy to build and at the same time quite useful as well. In this post, I will show you yet another thermometer/hygrometer build. But instead of using an LCD or 7 …
