need help

hello everyone! I am going to ask for a help in our project pls... we use HC-SR04 ultrasonic sensor for obstacle and distance detector but we found out that this kin of sensor is very sensitive in the wind. this sensor is not an outdoor use? if so, what kind of sensor we need to use? anyone can help us please... thank you...

What are you trying to detect or measure ?
For detecting the presence of people, for example, passive infrared sensors (PIR) or radar sensors are good. For measuring distance, some infrared (IR) methods are good.
Maybe say a bit more about this project to get a better answer.

Have you considered a radar based sensor?

hello @6v6gt . We are trying to detect the measurement of any physical obstacles in front of the sensor up to 1 meter . the PIR can do this and good for outdoor use?

Passive infrared sensors are not very useful in this application. These are intended to detect moving obstacles which have a different temperature to the ambient temperature. The cheap (doppler) radar sensors are not very directional and usually designed to detect movement, not static objects

Your bests options are probably Sonar (e.g. SR04) or IR proximity sensors (e.g. GP2Y0A02YK0F ) but here may be others too.

IR proximity can work under sunlight?
What if I will use ultrasonic proximity sensor ? or waterproof Ultrasonic HC-SR04 ? what do you think will be the best on this kind of project?
BTW. thank you for your help. I appreciate it :]

Hello everyone. is IR proximity can work outdoor ? it will be expose into sunlight,wind,rain(weather) IR can detect through light right? or much better to use ultrasonic? which detect through sound waves? it won't be affected in wind? what do you think guys? pls help :frowning:
