[SOLVED] Sleep dont run

[mar.conte]

@Yveaux
thanks for the lesson, really complete, tomorrow I will try to put into practice the advice then I put "high" and will default interrupt with a 10k resistor input pir sull'interrupt 1. Thanks'll let you know

[gohan]

@Yveaux how do you handle a pir sensor if you can't use the Change interrupt?

[Yveaux]

@gohan If you sensor signal goes HIGH the moment it detects movement one would sleep until the interrupt has HIGH level.
After sending a message it is important to wait until the signal goes low again before sleeping, otherwise the sensor will wake immediately.

[gohan]

@Yveaux sure, but I would like to avoid having a sleeping node that wakes only with motion and then reports "no motions" only when sleep timeout is reached

@Yveaux said in [SOLVED] Sleep dont run:

@AWI Your third example is out-of spec (CHANGE interrupt) and behavior is therefore undefined. If it seems to work, you're lucky...

Are you saying that the example posted here https://www.mysensors.org/build/motion contains mistakes ?

[Yveaux]

@tonnerre33 yes

[Yveaux]

@gohan I don't get your problem...
I suppose my suggestion will solve both waking from motion and sleep timeout.

[gohan]

If you have a motion sensor it will immediately wake when motion is detected but it will report pir sensor change to "no motion" only at sleep timeout, and if timeout is like 30 minutes then the controller will have "motion detected" on for 30 minutes. So unless you make an if statement with two sleep function, one with short sleep if pir sensor is on and one with long sleep if pir sensor is off, you will not be quickly notified of pir state changes

[Yveaux]

@gohan How about this ?
I think it covers the regular use-case (untested :baby:):

#define MY_DEBUG
#define MY_RADIO_NRF24
#include <MySensors.h>

unsigned long SLEEP_TIME = 10000;
#define PIN_PIR (3)

MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()
{
    pinMode(PIN_PIR, INPUT);
    // Configure what to send in case the PIR trips
    msg.set("1");
}

void presentation()
{
    sendSketchInfo("Motion Sensor", "1.0");
    present(CHILD_ID, S_MOTION);
}

void loop()
{
    // Sleep until woken by PIR motion, or timeout
    switch( sleep(digitalPinToInterrupt(PIN_PIR), LOW, SLEEP_TIME) )
    {
        case MY_WAKE_UP_BY_TIMER:
            Serial.println("Woke up by timer -- do something smart ;-)")
            break;
        case MY_SLEEP_NOT_POSSIBLE:
            Serial.println("Unable to sleep ;-(")
            break;
        default:
            Serial.println("Woke up by PIR -- sound the alarm!")
            send(msg);
            // Wait until PIR signal goes low again; poll every 100ms.
            while( digitalRead(DIGITAL_INPUT_SENSOR) == HIGH )
            {
                sleep(100);
            }
            break;
    }
}

Note the LOW level to wake the ATMega. Regular PIRs will generate a HIGH level on motion.

I can not solve the problem !!
I interrupt stabilized with 10k resistor, rewired everything but if my atmga + hcr501 +rfm69 with ftdi sleep in the consumption is 30 micro, if power with aa battery consumption is 420 micro help

[AWI]

@mar.conte The hcr501 will become unstable below 3V. So if you are powering it with 2AA you can expect problems.

[mar.conte]

@AWI
I have order 3,6 aa battery 2600 mah and try , i think what you say infact i have imagined this Tanks

[mar.conte]

@AWI
But I was thinking if it is true this should not works rather well the system works fine without false alarms and detection pir is precisely why?

[mar.conte]

SOLVED
HI
FOR 3volt power i have insert jumper in the pin H of hcr501 and my project in sleep mode consumption is 30 micro Tanks for you suggesrion
