@Eko-Febrian not sure I understand the question but the gas sensor example might be what you are looking for.

To refine your code: Try to use arduino IDEs "Tab"-Function. Add few tabs to organise your code. e.g. Tab "Network" with functions like init_rf() and just call this function from your setup() or before() method. Same with your actual sensors. Consider making an extra tab to put all the relevant functions there. I try to keep my "Main" tab as clean as possible. As I understand your code right your rf95 receiver acts as a gateway to mysensors MyMessage msg(NODE_ID, V_FLOW); // Set's up mesaaging protocol to reciever, lets it know what variables are used MyMessage vmsg(NODE_ID,V_VOLUME); // V_FLOW means that the data being sent is a flowrate, etc. All your Sensor-Nodes who send to your receiver-serial-gateway should have different IDs and your gateway should use these IDs to send the sensor date to your controller. So NODE_ID should be a variable depending on "from which node" you got your sensor date. Have a look at "MyMessage.h" // Setters for building message "on the fly" MyMessage& setType(uint8_t type); MyMessage& setSensor(uint8_t sensor); MyMessage& setDestination(uint8_t destination); You can change the message Sensor (your actual sensor no the gateway) dynamically on your gateway depending on the payload you get and from which sensor.

What Chinese are doing with this sensor which is used in a handheld air quality meters like this: https://a.aliexpress.com/_UCY55 is this -> Li-Ion battery 3000-4000mAh This would last hours. Not days. Unless you want to use a car battery, I do not think there is a portable pm25 monitor able to work days without recharging.

Didn't test this, but using a vibration sensor (modules are available under the namee "SW-420 Vibration Tilt Sensor Alarm" at big market places) might also be an option. Should provide digital and/or analog signals. Best success with your project!

@ThomasDecock No I wasn't, I was able to get the standard dallas temperature working(because I thought the sensors no longer work), but unfortunately my time on this is pretty limited. I hoped I got it working until I go on vacation, but probably will look into it after. I would appreciate if someone could help with it, I think everyone would.

@Dwalt said: Depending on your controller and what you plan on doing with this data, I would send the data to your controller as a simple number using V_LIGHT_LEVEL or V_VAR1 and not mess with atmospheric pressure with V_PRESSURE. or just use the temperature device... you can attach logic a lot easier with controller-friendly device types. Vera knows temperature, for example.

@jhussain the board is the one pointed out by @mfalkvidd and as for the wiring it is very simple: the door sensor has one wire connected to pin 3 (since interrupt based) and the other to ground, the flood sensor has one connected to pin 6 (can be any) and the other to ground.
