Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. It sensible to to flammable gas: Alcohol, and Methane etc. The voltage that the sensor outputs change according to the smoke/gas level that exists in the atmosphere. The sensor outputs a voltage that is proportional to the concentration of smoke/gas. In other words, the relationship between voltage and gas concentration is as following:
In this DIY Lesson, we’ll learn how to monitor the smoke detector remotely.
2 Hardware Preparation
|UNO R3 board||1|
|Ethernet Shield W5100||1|
|Gas sensor module||1|
3 Hardware connection
Connect the Gas detector sensor with UNO as following diagram:
|UNO Board||Gas detector sensor|
Log in Cayenne IOT platform, Add new…->Device/Widget
Click Analog Input, setting the datasheet as followed:
Please Note: If V1 pin was used by other widgets, you can select other pins. and change the VIRTUAL PIN in
sketch to the pin number you have selected.
In your dashboard, click “Step 1:Sketch File”, the sample sketch will be displayed. Copy and paste the sketch into Arduino IDE ,please remember to use your own authentication info. Upload to your Uno board, then click “Setp 2 :Add Sensor”, you will find the smoke sensors was added on your dashboad:
Once the smoke sensor detected any smoke the value will change.
