  • On Board Two Switches for PWM
  • On Board Power LED

 

 

 

 

 

 

 

 

 

 

Digital 2 Digit 7 Segment Thermometer Using PIC1825, CAT4016, DS1820

DIGITAL THERMOMETER (1)

This digital Thermometer provides real-time temperature values from 00 to 99 degrees Celsius. The Temperature Monitor  project built using PIC16F1825 Microcontroller from Microchip, CAT4016 serial to display driver IC from ON-Semiconductor, DS18200 Temperature sensor and two 7 Segment common anode 0.5 Inch display. This little handy project consumes low current and can be work with 4.5 V batteries, intensity of the display can be change by replacing value of R1, read Cat4016 data sheet for more information about current setting. Display range 00 to99 degree Centigrade.
