Anyone know of a breakout board for a SPM0404UD5 or any other similar ultrasonic MEMS sensor? I want to build a ultrasonic detector so I'm looking for something that can detect the presents of ultrasonic sound (if you could call it that ).
Thanks
I did more investigation played around with sleep outside of mysensors and found a bit of code in a proximity sensor example:
// Reset flag and clear APDS-9960 interrupt (IMPORTANT!)
isr_flag = 0;
if ( !apds.clearProximityInt() ) {
Serial.println("Error clearing interrupt");
}
I then needed to play around with delays to allow the sensor to catchup..
void loop() {
delay(1000);
Recoding back to MySensors
if ( !apds.clearProximityInt() ) {
Serial.println("Error clearing interrupt");
}
wakeupReason = sleep(digitalPinToInterrupt(INT_PIN), FALLING, sleepTime);
setting up the interrupt pin with a pullup forced the FALLING when pin dragged down by the sensor.
void setup() {
pinMode(INT_PIN, INPUT_PULLUP);
All this is on caveat it makes it through some more testing.
@popsyann said in Battery life for Motion Sensor:
When I load the motion sensor sketch, it start properly, finding the right "parent" and immediately after this, there is a flow of info going out of the Arduino+sensor, sending 0s or 1s, constantly (like if there was an issue with the interrupt process).
And what I do not understand is that this (these) sensor(s) has(have) been working well for a while.
Please search for sleep() function - it has changed the way it works at some stage in MySensors 2.*

Another reason could you that your PIR is not settling properly - this is why it sends out 1s and 0s to the GW. Try to insert sleep(20000); into void setup() at the end to settle the PIR
@BulldogLowell I fried my breadbord power supply by connecting broken power adaptor(it have me about 13-14V instead of up to 12V), this fried AMS1117 5V. I replaced it, and it's working proper again.
@secantscope I understand - It is a few years since I looked into this and then the only conclusion I could make was to take a meter and interface with usb. It would be more work and my needs case didn't warrant that at the time.
I am sorry I could not be of more help in this, but it just seems to be the way things have been for a while. Maybe in the future things will change.
As @nagelc suggested a lesser sensor could be used and you could calibrate it yourself. Seems little other options really. (Now I said that you just wait for a killer posting with just the thing you want linked) !!!
@Yveaux
Have you read datasheet here...
At the o\p side they mention unity gain amplifier with OpAmp
but the thing is that unity gain amplifier always produced same output volts!
@AWI i've since done some more work on this and discovered the switched 3.95v didn't share a common ground with the rest of the circuit. So i ended up hooking up a DIL reed relay PRMA 0105 (5v) onto it, and used the relay contacts to connect to pin D3 on my nano.
So i've got it operating that whenever the motion sensor is tripped it toggles my 1 channel relay board, but what isn't working is being able to manually switch it from in domoticz.
Would someone be able to take a look at my code which i've taken from this thread
