I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them.
@tiana I have not used it, but it is possible to create different revisions. See https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions as an example.
@ZenBlizzard in case you are measuring the output with a multimeter, you will get an averaged level, since AC current waveform should be sinusoidal and overlapped with the Vcc/2->2.56V in your case.
To measure the current you need a decently high sampling and some math.
#define SENSITIVITY 66 // mV/A
const float readings = 5;
const float alpha = 2.0 / (2 * readings + 1);
for (ifor = 0; ifor < 250; ifor++)
{
// Voltage
voltageSampleRead = analogRead(V) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/
voltageSampleSum = voltageSampleSum + sq(voltageSampleRead); /* accumulate total analog values for each sample readings*/
voltageSampleOffsetSum = voltageSampleOffsetSum + voltageSampleRead;
// Current
currentSampleRead = analogRead(I) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/
currentSampleSum = currentSampleSum + currentSampleRead * currentSampleRead; /* accumulate total analog values for each sample readings*/
currentSampleOffsetSum = currentSampleOffsetSum + currentSampleRead;
wait(1);
}
voltageMean = voltageSampleSum / ifor; /* calculate average value of all sample readings taken*/
voltageOffset = voltageSampleOffsetSum / ifor;
reading = (sqrt(voltageMean) - voltageOffset) * 230.0 / 1.0; // read voltage / reported voltage.
voltage = round_to_dp(alpha * reading + (1 - alpha) * voltage,1);
Serial.println(voltage);
if (voltage < 25) voltage = 0;
currentMean = currentSampleSum / ifor; /* calculate average value of all sample readings taken*/
currentOffset = currentSampleOffsetSum / ifor;
reading = (sqrt(currentMean) - currentOffset) / SENSITIVITY * 1000 - currentZeroOffset; // subtract no load current.
if (reading < 0) reading = 0;
current = round_to_dp( alpha * reading + (1 - alpha) * current,2);
That's right @gohan , if you place the "door closed"reed near the floor then only first interrupt should matter, first interrupt should tell you the door is closed. Same for a second reed placed high - the "door open" reed, that would tell you the door is open when interrupted the first time. @McQueen, could be close to you needs ...
Hey guys,
I was justing wondering, is there a way to deactivate the motion sensor if not being used? Eg: My motion sensors are connected to Homeseer and they show up as sensors but I was wondering if I could have an ON / OFF control to deactivate or active the motion as needed.
Damm I am trying to get this working with a Arduino pro mini ,,but no luck wanted to use it in the car ..
How do you wire the NRF24L01+ ???
N-Channel Mosfet s ??? model number please any help much appreciated
I have tried mosfets >>>irf510n
@zmatokan said in NModule:
@Nca78 Are you still working on this pcbs? i think it would be great to add a version that supports HiLink 220ac->5dc module on powerboard.
No I'm not working on NModules anymore, I have a few old nodes using atmega/nrf24 but I switched to NRF5 for "basic" nodes now, and to ESP32 for more "advanced" stuff.
NModule was designed for beginner and simple/riskless use, so I don't think adding high voltage option is a great idea, it's better to use an external power supply and connect the output to the powerboard.
