Introduction
In such projects temperature, it is of fundamental importance to check the operation of the temperature sensor, before starting the operation of reading the data.
It is important because in the case of Sensor failures, the temperature monitoring device will not be able to detect variations in the system temperature.
Therefore, in the case of system temperature failure, the device won't be able to detect the variation and accidents and malfunctions may occur.
So, as the way to avoid these types of accidents, we will develop a system capable of verifying the operation of the DS18B20 temperature sensor and indicate when it is in normal operation in the system and inform the LCD 16x2.
Development of the System
Several temperature monitoring devices use the DS18B20 sensor because it is a digital sensor with great accuracy in temperature measurement.
And due to its great applicability, we must ensure the safety of the system equipment by monitoring its operation.
In this way, we present an electronic schematic of a circuit with Arduino, to present the temperature of the process and verify the operation of the sensor.
