This project collects temperature and humidity data using a DHT22 sensor connected to an Arduino. Data is sent via a Python bridge to a Flask backend, which validates and stores it in MongoDB. The ...

The temperature sensor is built using an NTC 10k thermistor, which changes its resistance in response to changes in temperature. The resistance of the thermistor is ...

The first step is a thermistor, a conceptually simple device: resistance varies with temperature (seriously, how much more simple can a sensor get?). You can measure them by tapping the center of a ...

Thermistor is a semiconductor device made of materials whose resistance varies as a function of temperature. A thermistor can be used to compensate for temperature variation in other components of an ...

Keeping track of things like the temperature, humidity, and smoke level in your house is important. If you want to make your own system for doing so, Instructables user ICStation shows off how to use ...

Check out a new post on the Arduino blog, showing how to build your own Bluetooth Smart thermometer, based on a Genuino 101, a digital temperature sensor and smartphone app. In terms of components, ...
