hi guys
i have Arduino Uno R3 with no other parts
i want to build a smoke and heat detector to drive a servo motor to close a small valve in case of fire or smoke ( you may ask why i chose two sensor that because some time the area is well ventilated)
i searched the web and found that ( MQ2 sensor ) works best
is it true ?
if not can you please give me a part list and code with wiring diagram
thank you guys , love your community
Welcome to the forum
Need more information on the usage. You can’t spec something without knowing what it is for and the environmental requirements
That is not the way forum works.
If You post a link to the datasheet of the MQ2 it would help to verify You're on a useful road.
right now i'm using simulators not actual parts
just a small servo motor connected to a small gas tank valve when it detect carbon monoxide it operate the servo motor to close the valve , I want it in my high school chemistry laboratory
That tells nothing. Physical size has little correspondance to electrical needs.
Turning a valve calls for more force/torque than those hobby toys produce.
Do You know the difference between a servo and a servo motor? It´s huge.
Simulation..... Anything works there but reality is often much harder.
You have to be more specific.
I'm sorry but i am new to all of this , i searched for servo motors and steeper motor but i do not know the deferent , but can you please guide me . you get the whole idea i want . so what parts do i need to do my idea ?
A servo motor spins around and around. A servo makes precise moves usually between 0 and 180 degrees.
You need to know the force/torque the servo must produce.
put a spring load/weight measuring device on the valve, pull the measurement device and note the 'force' necessary to move the valve. The measurement should give you an idea of what torque value you'll need for a motor/servo. Pretty basic science stuff.
This does not seem like a reasonable DIY project.
Use a commercial CO alarm.
here is a good hobby grade C02 sensor,
