Hi there,
it's me again.
I tried some things which read in the arduino froum (http://forum.arduino.cc/index.php?topic=153700.0) without any good result.
I also get a new sensor and there is still no change of it's behaviour.
I read in the forum that it could be a sensor that uses RX/TX to send its information.
Does any one know something about that?
OK. this threat (http://forum.arduino.cc/index.php?topic=153700.0) is very usefull. I will try out some hints and tell you my result.
Thank to all for now.
@hek Thanks. I will check out this and will tell you the result.
@Moshe Livne I order the HC-SR04 Module as well to make sure where the problem is.
I also order aother Arduino Nano.
Hi all,
I am really wondering whats going wrong here. I made some changes to the code and now I get this result:
Ping: cm
Ping: 0cm
Ping: 0cm
Ping: 0cm
Ping: 2cm
Ping: 0cm
Ping: 0cm
Ping: 0cm
Ping: 1cm
Ping: 0cm
Ping: 0cm
Ping: 0cm
Ping: 0cm
Ping: 0cm
Ping: 0cm
Ping: 16cm
Ping: 0cm
Ping: 0cm
Ping: 0cm
The distance between sensor and wall is about 75cm.
I took back any chagnes I made. Without any effect.
I try now use the NewPing version 1.6 library. No effect.
Current code:
#include <NewPing.h>
#define TRIGGER_PIN 6 // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define ECHO_PIN 5 // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 500 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.
NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.
void setup() {
Serial.begin(115200); // Open serial monitor at 115200 baud to see ping results.
}
void loop() {
delay(2000); // Wait 50ms between pings (about 20 pings/sec). 29ms should be the shortest delay between pings.
Serial.print("Ping: ");
Serial.print(sonar.ping_cm()); // Send ping, get distance in cm and print result (0 = outside set distance range)
Serial.println("cm");
}
I there any way to check I the hardware is bad or may have some defects?
Hi Moshe Livne,
I disconnect the radio device and keep the US-sensor connected and use the following code.
#include <NewPing.h>
#define TRIGGER_PIN 6 // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define ECHO_PIN 5 // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 500 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.
NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.
void setup() {
Serial.begin(115200); // Open serial monitor at 115200 baud to see ping results.
}
void loop() {
delay(500); // Wait 50ms between pings (about 20 pings/sec). 29ms should be the shortest delay between pings.
unsigned int uS = sonar.ping(); // Send ping, get ping time in microseconds (uS).
Serial.print("Ping: ");
Serial.print(uS / US_ROUNDTRIP_CM); // Convert ping time to distance in cm and print result (0 = outside set distance range)
Serial.println("cm");
}
I got the following results:
Ping: 306cm
Ping: 0cm

No.
It is powerd with a 5V and 2A powersupply.
Hi BulldogLowell,
sorry for the delay I was over 2 weeks on vacation. but now I am back.
I using the code from the distance sensore example (http://www.mysensors.org/build/distance).
#include <SPI.h>
#include <MySensor.h>
#include <NewPing.h>
#define CHILD_ID 1
#define TRIGGER_PIN 6 // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define ECHO_PIN 5 // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 300 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.
unsigned long SLEEP_TIME = 5000; // Sleep time between reads (in milliseconds)
MySensor gw;
NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.
MyMessage msg(CHILD_ID, V_DISTANCE);
int lastDist;
boolean metric = true;
void setup()
{
gw.begin();
// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Distance Sensor", "1.0");
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID, S_DISTANCE);
boolean metric = gw.getConfig().isMetric;
}
void loop()
{
int dist = metric?sonar.ping_cm():sonar.ping_in();
Serial.print("Ping: ");
Serial.print(dist); // Convert ping time to distance in cm and print result (0 = outside set distance range)
Serial.println(metric?" cm":" in");
if (dist != lastDist) {
gw.send(msg.set(dist));
lastDist = dist;
}
gw.sleep(SLEEP_TIME);
}
Oh, I forgot to mention that I use a DYP-ME007Y Ultrasonic Sensor Module.

Hi there ,
I have built a distance sensor to measure the level of my rainwater tank. I built it with an Arduino Nano. I use an Arduino Nano as a serial gateway as well.
The communication between the two work well. The values in my controler (FHEM) are visible.
The main problem is strange values, I get.
The values jump between 0 and 400, even if the distance changes to the sensor head.
I attache a out put from the serial console.
Don't worry about the fail. The sensor has currently no contact to it's gateway. But this is no the reason for the stange behaviour.
