One temperature sensor is using in this project to check temperature reading. We also have two trigger value for temperature. One is for over temperature & one is for over temperature. Both trigger value can be change & also visible on LCD. Normally Our relay switch is On, & connected device with relay is also on. Device can be any ac or dc device but we are using one 220V AC lamp for demo purpose. As current temperature increase & touch to over trigger value then relay will off & also attached our lamp will goes off. As temperature fall below under threshold value then relay switch will automatically on. This type device can be used for temperature controlling purpose for oven , furnace etc.
Project customization is also available.
