Viration sensor

A new sketch using a simpler vibration sensor than the one on the store, this one has only one output to go into digital pin 3 hich is PWM.

VibrationSensor.ino

The sketch uses the interrupt to count the value between too sending to gateway (sleep time).

Globally the sensor is not that much sensitive, some people use the piezzo one for seismic activity monitoring, this one is more door knock measurement. As I write, it is on my keyboard and does not report anything, but if I knock on the keyboard a value is reported.

@hek I would need a value too for this one...

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@Paul-Scarbro There are multitude of solution, but since we are in MySensors Land, let's do a MySensors solution. You'll quickly see that doing that adds a lot of overhead. We'll use an Arduino Nano or RF Nano if you're going to go whole hog. It can be run from 3.3V or 5V DC, not AC. The reed switch would be connected to an input of the Nano and one of the outputs would drive a relay. The relay would drive the chime. Your C++ program would be something like: #define inputButton 2; // connect reed switch here #define outputRelay 4; // connect relay to this pin see MySensors Relay example #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay void setup() { pinmode(inputButton,INPUT); pinmode(outputRelay,OUTPUT); // put your setup code here, to run once: } void loop() { // put your main code here, to run repeatedly: if (digitalRead(inputButton) == 0) { digitalWrite(outputRelay,RELAY_ON); wait(2000); // wait 2 seconds digitalWrite(outputRelay,RELAY_OFF); // now wait for door to close while(digitalRead(inputButton) == 0) ; //does nothing until reed switch opens } } There are some subtleties that I may have glossed over, but this is the gist. By looking at the MySensors Relay example, you'll see how to integrate this into a MySensors environment. That's where you'd want to get the RF Nano. I've made the assumption you're familiar with the Arduino IDE and you've looked into the MySensors environment.

Quick Range Check on the WIO-E5-LE. The LE version uses only the low power PA, +14dBm max. Using the default settings except for 915MHz #define MY_SX126x_FREQUENCY (SX126x_915MHZ) #define MY_SX126x_LORA_SF LORA_SF7 #define MY_SX126x_LORA_BW LORA_BW_125 #define MY_SX126x_LORA_CR LORA_CR_4_5 I get about 190 meter range, just walking around the neighborhood, line of site except for some trees and power lines. No tuning on the antenna. Just using a 77.9mm wire. Not as dramatic as some have achieved with LoRa radio's, but plenty good enough for my house and yard : )
