Hi all,
I'm going to realise step by step my WeatherDuino Pro2: First RX unit, second TX unit and go on.
But there are few uncelear points for me. Could someone please explain?
1) What is purpose of the "fan" in TX unit?
2) Both of SHT11 and DHT22 has a temperature sensor. So why is there an other temperature sensor? (TMP36)
3) What is the pin explanation of the wind and rain sockets? (i.e.
pin 1: power
pin2: digital data for wind direction
pin 3: ....)
Answer of third question wil be very useful to prepare DIY solutions.
Regards.
Recep
