About: I'm a maker. I love to create, I love to travel and I never stop dreaming...

The SR04 ultrasonic sensor is a very popular sensor among makers all over the world.

It is a sensor that allows you to measure how far away an object is.

For example, I used it in the Green Detect wireless sensor network platform to measure the height of a river and thus prevent a flood.

With this project I wanted to make a case to be able to use the sensor in outdoor projects and therefore protect it from dust and humidity.

I think this simple instructable can be very helpful for all of you, hope you like it!

Attachments

Step 2: Fix Cable and Gland to the Case Hole

Fix the cable gland and pass the cable that will connect to the sensor inside it

Step 3: Fix SR04 Sensor to the Cover

SR04 sensor must be fixed to the cover using hot glue.

Step 4: Connect the Sensor

Connect the wires to the sensor.

I suggest you to improve the fastening of the connection with hot glue

Step 5: Close the Box

Fix the cover with 4 small self-tapping screws
