you need to include a option
,
:with=>"'state='+document.getElementById('selected_district_state').value")
for your periodically call control..
<%= periodically_call_remote(:url => { :action=>"show_current_readings" },
:frequency => 5,
:with=>"'state='+document.getElementById('selected_district_state').value")
%>
I will send more hints later.
