Arduino Expert for Environmental Control
Budget: $10 – $30 CAD
I am trying to use an arduino to control humidity in an out building which has no heat or dehumidifier.
Simply put, I have a DHT22 to monitor outside humidity and temperature and a second DHT22 to monitor inside humidity and temperature.
The results are to be displayed on a 20x4 I2C LCD display.
When the outside humidity is lower than the inside humidity, I want to energize Relay 1
Materials used: Arduino Uno, 1 Channel Relay, 2 DHT22 Sensors, 20 x 4 i2C LCD display
