This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very ...

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 ...

After the temperature sensors detect deviance from the set point, or upon SMS instruction, the Freeduino will crank up the heat through a 5V relay attached to the home’s boiler.

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

This is the type of thing you could throw together with a microcontroller hobby board (i.e. Arduino and the related diaspora), a couple temp sensors (whether thermistors on analog pins or I2C temp ...

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 ...

It is described as an “open platform” that can collect temperature from multiple sensors, apply programmable control logic, and drive different loads with a precise PID algorithm. It is built around a ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home.
