Humidity and Clock display simultaneously

Its mechanical strength and thermal stability are good enough to bear the temperature changes from the reflow soldering and the outside force

ATMEGA328P Microcontroller IC Multiturn These are Carbon Film ResistorThe ATMEGA328P ( P stands for Pico power ) is the low power modern version CMOS 8 bit microcontroller based on the AVR enhanced RISC architecture. 8 bit means the processor uses an 8 bit register, which can handle 2^8 or 256 data values, which seems low for todays standards. However, the higher the bit count and processing speed, the more power consumption the processor uses, hence, why microcontrollers are a favorable choice for low power solutions.
