Project description
Author used HW below Arduino or Freeduino microcontroller (with ATmega328); Ethernet-shield Wiznet w5100; Digital temperature sensor DS18B20; Atmospheric pressure sensor BMP085; Humidity sensor DHT22; Resistor 4.7 kOhm; Resistor 5 kOhm. DS18B20: DHT22: BMP085: HW connection Resistor R1 in the diagram is 4.7 kOhm, it is used to pull up the data line for the DS18B20 temperature sensor. Resistor R2 - 5 kΩ, pulls up the DHT22 data line. The temperature and humidity sensors are placed outdoors. I used a four-core telephone cable for this - it works great at a distance of 6 meters from the…
