LDP0021: Temperature and relative Humidity (sensor DHT22) shows at separate LED displays - FREE!
The offered code enables: Temperature and humidity value shown on 2 separate displays
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 (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/P2 Display(1-2) brightness selection potentiometer (0-7)
