I want to sense the temp by LM35 n i have an condition 2 be set up at 20'c (if the temp is above 20'c the my relays will remain set otherwise will remain reset)...now im getting 200mV at 20'c at Vout pin of LM35 , now what should be the condition set for the atmega16 i.e in programming (i'm...
thank you for ur advice , it means that it is to be just connect an pot between the supply and one of the LDR terminals and adjust the pot to vary the light intensity levels....whenever the light falls below some level it would give +5V to the port connected..
thank you for ur help, this means that i have to only keep the condition in terms of millivolts what ever i require n when ever the condition is true it would give me a logic 1 on any determined pins....
Hello,
i want to interface an LDR with atmega16,..I need to control n measure the light intensity and obtaining the logic 0 or 1 at any pin of port A when ever the light intensity falls below certain level..help me with the circuit n programming ...
Thanks..
Hey,...
I want to use LM35 for sensing the room temperature with the atmega16, i need to adjust the temperature ie if room temp falls below 20c then i need logic1 or 0 on the ADC0 port or at any port..
pls help me with the circuit n programming ...
thanks
Hey ,I want to connect ADC0809 to LM35 & LDR , to my 8051,& I dont know how to connect it in terms of hardware n will i need to program ADC for its operation, i want to operate relay relay with help of LM35 N LDR...
Hello ,
I am using an ADC809 & i am using 1 analog o/p of 3 sensors each now how to interface it with 8051, I am using only 3 i/p pins of ADC .I am connecting LDR, LM35 to it .pls help me..
thank you very much for your feedback , so according to you i can directly connect it to the controller ...i was having the same data sheet but was still confused as it was not clearly mentioned..

hello, the data sheet says that it gives high/low level signal of 3.3v with...
I have an PIR sensor module BS1600 and i want to interface it with the microcontroller , but i dont know that the output of it is in TTL form or not as i want to give it to controller so that it can operate the relays connected to it.
