Digital & Binary clock with thermometer & hygrometer

Here we have a clock. It’s not “another clock”. It has digital and binary output. It also has a thermometer and a hygrometer. It’s not “another thermo-hygrometer”. It display’s absolutely humidity (gr/m3) also. Schematic   MCU I build it around Microchip PIC16F917, with internal Oscillator at 4MHz. I also build a serial port programmer, so I can programming it on-line, using the DL4YHF WinPic. Clock I ...

TrH Meter: A DIY indoor thermometer plus hygrometer with adaptive brightness control implemented to 7-segment LED displays

This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor (LDR) a ...
