Hi..im new to cytron.
I want to buy few sensor from here, but im confuse of the sensor part.
What sensor should i use to detect obstacle..? with simple circuit.
Obstacle
1. IR sensor, it faced a problem of my previous project, Line follower. It easily kacau by ambient light. If i use it in firefighting robot, my sensor has to sense range from 10cm to 20cm. It is very sensitive if i wan sense between that range. Please give me advice.
p/s: i've used one type of IR,RM1.50 per piece. Got better IR sensor? more range and won't kacau by room light and sunlight.
2. Ultrasonic. I don't even know how to use it, the circuit seems more complicated than IR sensor.
Flame
1. UVTron. Too expensive.
2. IR. can it detect candle flame?
3. heat detector. how to use it?
Pls advice me.
I'm seeking from your fast respond. Thanks!
