GolamMostafa:
The recommended sampling time for DHT22 is 2/2.5 sec.The conversion time of a 12-bit resolution DS18B20 is maximum 750 mS (in worse case let us take it as 1-sec). Even, we make a sequential operation of two DS18B20 sensors, the cumulative delay is maximum 2 sec. So, after 2-sec delay, we are reading the response of the DHT22; we are not missing the data of DHT22! Then --
Why are you expressing the quoted text?
ya so my whole print code is a 4 second milli delay, or did you miss that?
explain to me again why request.temperature isent at fault?
