Doing that, and using this script, I think it will be audible if you're in the same room as it (and if the room is otherwise quiet).

Guess this is not made for Vietnam then :D
I supposed this type of buzzer is made more for user feedback for things like touch sensors, than for raising alert.

@nca78 What strange is that if I cup my hand over it, it actually becomes louder. Not sure what's up with that. So, maybe I'm just not driving it right.

Here's the latest version of the PIR sensor embodiment:

It runs from two CR2032's.

Very compact! :)

@neverdie how do you connect thr two Cr batteries ?

Another question ? I read in another comments that you need 100-200 uF capacitor so that the radio can work since thr CR battery wont be strong enough. Did you add this ?

This was recently discussed in the Bluetooth action! thread.

Isn't that the principle for most speakers, using a sound box ?

Wich board do you use in arduino? I can only use Waveshare BLE4.0. At Generic etc. It seems, that the oscillator doesn't work probably.

Not sure what you're asking.

Tiwo85

@neverdie I mean this:

When I use Generic nRF51 or something else, the onboard LED turns on and doesn't turns off. When I use Waveshare BLE400 the sketch works as usual

NeverDie

@tiwo85
I use this:

You download it from @d00616 on github.

Tiwo85

@neverdie do you have a working example sketch. I try the example sketch from the 10years pir sensor an d modify a little bit, but it doesn't work. The sketch awake every 5 minutes and send the state from the pir and that's it.

@neverdie thank you. I made this sketch work. But I need to get work interrupts. I use your code for the am612, but it doesn't work. Then I use the example from Redbear labs "Example interrupted" to turn on the led when p0.02 is high. I use Mysensors library and set My Core only. Then it runs. But when I try to integrate Mysensors routines "presentation" etc. And disable "my core only" , then the interrupt doesn't work.

// SUMMARY: This demo sketch runs on the AM612 PIR v607 PCBto transmit battery voltage (heartbeat) and motion detections to a MySensors gateway using MySensors protocols.

// Note: because this is a passive node, node ID must be set manually to a unique sensor node ID:
#define MY_NODE_ID 143  // Passive mode requires static node ID

//#define MY_CORE_ONLY

#define MY_PASSIVE_NODE

#define MY_RADIO_NRF5_ESB

@tiwo85 I suggest you start a different thread on your interrupt problems, since that's really a separate issue and not specific to this hardware.

Hi,

I like to buy this board and your AM612 breakout pcb through hardware.io.

But first I have few questions unfortunately I couldn't find the answers here in this thread/forum.

I assume this board has to be programmed via the 10pin box header. How can I connect it to my computer? I think there is some adapter or similar required? Any selfmade options available? In this thread I saw that it should be possible to program this device via the Arduino IDE?
Can I mount the following sensors at the same time without space conflicts:

Motion PIR (AM612breakout)
Temp + Humidity
Light

Does this board have some free digital pins for door contact and or relais? (if yes, how many?)
(Optional) I think there are no MISO/MOSI/... pins for connecting a RFM69 module?

I don't like to use the battery option. I will power the board via power supply. Can I connect a 5V power supply to the battery pins or what is the best option?

Thanks in advance.

Hello @ehome

it is based on an arduino pro mini (NModule board, don't forget that this is just a shield for NModule) , so you program the arduino pro-mini, usually using an FTDI adapter. You should find plenty of explanations online.
For programming bootloader/fuses, you can use and arduino nano with the ArduinoISP sketch: MOSI=>MOSI, MISO=>MISO, SCK=>SCK and SS (pin 10) of nano to reset pin of the pro mini. Here also you will find plenty of examples/videos etc online.
Start with reading the page about NModule:
https://www.openhardware.io/view/364/NModule
In theory yes if light sensor is on the AM612 breakout. I will test this configuration next week and confirm to you that it is working before you order the board. If you don't hear any news about that before the end of next week ring me a bell here as it probably means I forgot :)
You will use one of the external interrupt pins (pin 3) for the PIR sensor, so you will have one left (pin 2). If you don't use the leds there are 3 other input pins available on the NModule connector (A1,A2,A3, you can use them as digital inputs too), on battery powered sensors it needs pin change interrupts, but as you are using a power supply it won't be a problem.
No you can't connect a RFM module, NModule is only for SMD NRF24 modules
You should connect power to RAW and GND pins on the NModule connector. The best is to use AMS1117 regulator to get the 3.3V, it's probably overkill for your usage but it's very stable and will filter the noise of your power supply much better than the XC6206 (which more suitable for a li-ion powered node). In addition you will be able to use a power supply up to 12V

@Nca78 many thanks for your answer. Maybe may question was a little bit too vague. I didn't mean the NMODULE board. I was speaking about the NRF51xxx board from @NeverDie

These are shield made to work with the NModule. For the same sensors I think @NeverDie has what you need in NRF5 versions, so ask him on the right thread :)

Hi all, i try NRF51822-04 module with this sketch and Si7021 as GY-21 sensor, communication over radio works great, but i still got Humidity 118% and Temperature 128°C

can anyone help me?

Si7021 is connected to P0.10 - SCL and P0.4 - SDA

I've downloaded the source files and tried to compile them.
I got fatal error: sketch/MyBoardNRF5.h: No such file or directory
Then I renamed MyNRF5Board.h to MyBoardNRF5.h
I got #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.
Then I added #define MY_GATEWAY_SERIAL into the code
I got many errors i.e. 'PIN_AIN0' was not declared in this scope

How to compile the downloaded source files?
