Digital Thermometer using Arduino and LM35 Temperature Sensor

image-1928
Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using Arduino Uno. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55 to +150°C

Analog to Digital Conversion – Arduino

image-1898
Analog to Digital converters allow analog continuous voltages to be converted into a discreet digital numbers inside the microcontroller as the microcontroller can only process digital numbers. This can enable the Arduino to be connected to analog sensors such as temperature sensors, pressure sensors, humidity sensors, optical sensors, and power sensors. Any sensor which can generate a voltage between 0V and a maximum 5V can be used.

MPLAB® Code Configurator

The MPLAB® Code Configurator (MCC) is a user friendly Graphical User Interface (GUI) plug-in tool for MPLAB® X IDE which generates easy to understand C code that is inserted into an MPLAB® X project, based on the settings peripherals configurations and selections made in the Graphical User Interface (GUI). The generated code can be used in any application program. When starting out with a new project using Microchip 8-bit microcontrollers, setup of the configuration and all the peripherals can be time consuming, especially for new projects. The MPLAB® Code Configurator simplifies this down to a series of simple graphical selections from the menus within the MCC.

Temperature Logger to SD Card with Menu Control – MikroC

image-180
An SD Card can be used to log data continuously over time for various purposes, this project shows the design of a temperature data logger with menu control system. The ambient temperature is read every minute and stored in a file on an SD card. When the program starts, the user is given three options: Saving the temperature readings to a new file on an SD card, Appending the temperature readings to an existing file or Sending all the saved file contents to a PC The user will have to choose one option and then press enter to start logging data. This menu only accessible once when the program starts, if the user wants to choose another option, he/she has to restart the program by pressing the reset button.

Analog to Digital Converter with PIC Microcontroller – MikroC

Analog to Digital converters allow analog continuous voltages to be converted into a discreet digital numbers inside the PIC as the PIC can only process digital numbers. This can enable a PIC to be connected to analog sensors such as temperature sensors, pressure sensors, humidity sensors, optical sensors, and power sensors. This is a nice feature to use as most of PIC microcontrollers today have built-in analog to digital converters (ADC) with the number of channels depending on the number of pins a particular microcontroller have.

This is a nice feature to use as most of PIC microcontrollers today have built-in analog to digital converters (ADC) with the number of channels depending on the number of pins a particular microcontroller have. Flowcode has an ADC component that samples analogue voltage input levels in relation to the reference voltage. the resulting value is then stored in memory ready to be retrieved as needed.

Analog to Digital converters allow analog continuous voltages to be converted into a discreet digital numbers inside the PIC as the PIC can only process digital numbers. This can enable a PIC to be connected to analog sensors such as temperature sensors, pressure sensors, humidity sensors, optical sensors, and power sensors. Any sensor which can generate a voltage between 0V and a maximum 5V can be used. If the output voltage is higher than 5V, a method to step it down should be used such as a voltage divider with resistors.
