I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

The device is simple — it uses an Arduino Nano hooked up to a thermistor to measure the temperature of fluid in a pot. The microcontroller displays the current temperature and the target ...

Adding a photoresistor (light sensor) and a thermistor (temperature sensor) and connecting them to a programmed Arduino gave me a gadget that monitors the environment of a single plant.

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 ...

The system here monitors temperature, humidity, and smoke levels and alerts you if those levels reach a certain point.
