sushma on updating multiple fields to thingspeak

What does your command look like?

thank you.

the code is,

// This sketch uses a DHT11 sensor to report temperature, humidity and dew point data to http://www.thingspeak.com.
//
// Sketch tested with an Arduino Uno, a HanRun Ethernet shield and a DHT11 temperature and humidity sensor.
//
// See http://playground.arduino.cc/main/DHT11Lib for the origins of the temperature, humidity and dew point functions.
