Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor – MikroC

image-136
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 MikroC Pro for PIC compiler. 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

Microcontroller Interfacing – Sensors

image-476
Microcontrollers have become very useful in embedded design as they can easily communicate with other devices, such as sensors, switches, displays, keypads, motors and even other microcontrollers. A microcontroller is basically used as the brain or intelligent processing unit to control other devices connected (interfaced) to it in embedded systems just like a PLC is in industrial automation. Interfacing a device with a microcontroller in simplest terms simply means to connect a device to a microcontroller. This article will make it easier to anybody with very limited experience in electronics to learn how to interface different sensors widely with a PIC Microcontroller.

Temperature Logger to SD Card with Menu Control – MikroC

image-90
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.

Automatic Temperature Control System using PIC Microcontroller – MikroC

image-66
An automatic temperature control system has the ability to monitor and control the temperature of a specified space without human intervention. This project uses a PIC microcontroller to automatically control the temperature of an area. This area could be a small plant, a house or any place or device that require a controlled temperature like an incubator (egg) for example. The desired temperature setting is entered using a keypad. The temperature of the area is measured using an analog temperature sensor. The microcontroller reads the temperature continuously and compares it with the desired value. If the desired value is higher than the measured value, then the heater is turned ON to heat the area. If on the other hand the measured value is higher than the desired value, then the fan is switched ON to cool off the area until the required temperature is reached. If the temperature reaches a certain critical value 40⁰C or higher, the buzzer will sound continuously and an LED will blink until the temperature deceases below 40⁰C. An LCD display shows the measured temperature continuously. This project can be used as a base for Final Year Project For Engineering Students

This area could be a small plant, a house or any place or device that require a controlled temperature like an incubator (egg) for example. The desired temperature setting is entered using a keypad and stored in microcontroller EEPROM even if the there is a power off or system reset, this reference value will always be saved. The temperature of the area is measured using an analog temperature sensor. The microcontroller reads the temperature continuously and compares it with the desired value. If the desired value is higher than the measured value, then the heater is turned ON, if on the other hand the measured value is higher than the desired value, then the fan is switched ON.
