Digital Temperature Monitor Using Woodstove

The goal of the project is to be able to monitor the temperature of a wood stove for in order to prevent overheating or exceeding the temperature limit.

This project has been created since a device specifically designed to monitor wood stove temperatures and sound an alert if the temperature exceeds the upper limit is not available commercially. It may lead possibly to fire or may damage the stove if it exceeds the safe operating temperature.

Depending on the probe installed, it could send out an alert if the stove gets too hot aside from monitoring the temperature. To make a magnetic mount temperature sensor, an alnico horseshoe magnet and a thermocouple were combined to make it easily attached on the stove. A flashing LED/piezo alarm is also wired to the controller. The alarm will flash red and sound when the set temperature is exceeded. After the temperature falls below the set point, the alarm will reset.

The alarm can also be silenced by a button. It consists of a relay and a push switch. The type of thermocouple determines how the controller will be set to monitor the temperature.
