Hi to all. I really need your help. I will go throught all my steps which was done. First of all, I would like to do the project with temperature sensor- classic project. However, here started my problems. Firstly, I’ve tried to connect DHT11 sensor directly to the arduino Uno board. I used this code: #include
#define dht_dpin A0 //no ; here. Set equal to channel sensor is on
dht DHT;
void setup(){
Serial.begin(9600);
delay(300);//Let system settle
Serial.println("Humidity and temperature
");
delay(700);//Wait rest of 1000ms recommended delay before
//accessing sensor
}//end “setup()”
void loop(){
//This is the “heart” of the program.
DHT.read11(dht_dpin);
Serial.print("Current humidity = ");
Serial.print(DHT.humidity);
Serial.print("% ");
Serial.print("temperature = ");
Serial.print(DHT.temperature);
Serial.println("C ");
delay(800);//Don’t try to access too frequently… in theory
//should be once per two seconds, fastest,
//but seems to work after 0.8 second.
}// end loop()
which worked for me. However, I need to collect analog data with one xbee module and send it to the second Xbee which is connect to the arduino.
I have configured 1 module like this:
Zigbee Router AT
PAN ID: 1234
Channel Verification - 1
ADO- ADC
IO Sampling Rate- 64
this module is connected with DHT 11 sensor. I use 5V for chip and for sensor, also grounding and data from sensor are connected to AD0 pin.
the second xbee module:
PAN ID- Coordinator AT
PAN ID- 1234
this module is connected to the arduino - 5V to 5V, GND to GND, TX to RX and RX to TX
The code on arduino I did not change- if you have any idea how to configure it, I will really appreciate it.
Also is any way, how to show data directly in XCTU? When I connect coordinator directly via USB port, I see nothing in Terminal. I would like to test, if data are going to the router. Also find where the problem could be. I tried to measure voltage on sensor- it has around 2 Volts (Data pin- GND)…
Really thank you for answer what I should to try. How to test it and of course, to bring this case to final
try to use rezistor, much bigger, much better as I can see it. already it is giving me unrealistic value, however it just look like problem with maths or just try bigger rezistor. When I will solved it to realistic values, I will give my code/ pictures .
