LDP0020: Measurement temperature and relative humidity (sensor DHT22) and show at one LED display - FREE!
The offered code enables: Temperature and relative humidity value shown on one display
Required accessories: - see above
For Arduino boards: NANO or UNO or MEGA
Arduino pins are used:
uc ATmega328p (NANO, UNO, ...): (see connections)
uc AtMega2560 (MEGA,.............): (see connections)
 
Electrical and practical notes:
Uses 9V/1A external power supply (VIN/GND) on DC plug (or external 5V/1A on 5V/GND pin).
If you want to use a longer length of the sensor connection cable, use a resistor of smaller value R1 = 2,2K
Display of the both measured value is in the form of one decimal digit.
Use specified type of 7 segments display with decimal points only (not clock dots).
S1 switch selector for temperature display in Celsius or Fahrenheit
P1 Display brightness selection potentiometer (0-7)
