DHT11 incubator with I2C LCD (part 1)
DESCRIPTION
DHT11 is applied as a sensor for temperature and humidity. To control temperature, a relay is used and connected to heating elements. Humidity and Temperature are displayed on a 16x2 LCD via I2C/PCF8574. On the next iteration, there will be:
However, other incubator implementing LM35 as temperature sensor is already explained on this link
EQUIPMENT IN USE
This incubator uses a clone of Arduino UNO, DFRduino v2.1, a DHT11 sensor, a relay, and a LCD 16x2 connected to I2C module (PCF8574).

- an additional relay to control a cooling fan
- humidity control via pneumatic parts
- button as controls to set the TempTarget and HumiTarget.
