Is there a way to allow the Arduino to continue even if it is not plugged into a router so cannot receive its DHCP data?

Instead of making a shield you can do the same thing with an SHT21 and a BMP085 that way you get 2 temperature readings and you can get your code to take an average of the two for better precision

I am currently using SHT21 sensors for my project

they are however incredibly small so kind of a pain to solder but they give humidity readings and the temperature in Celsius and Fahrenheit.  I think they are about £10 a pop.

the problem i am having is that the get humidty and temperature are all floats

sorry guys im having some problems working out how to that.
im trying to get  mac, unixTime, temp, humidity  in that order in.

I can't work out how to convert everything into the right formats and get the unix time out

oh ok
so if i were to place GetHumidity within the packet definition would that be a string or int? same for get temp
thanks

so if I want to send the humidity.GetHumidity() and humidity.GetTemperatureC() as well as sending the current MAC address and the unix time I have just received all in one packet what would the structure of that section be?

Also is it possible to have it work out the packet size itself?


Thanks for the fast reply
