SR04 Ultrasonic Sensor Case

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!

1. SR04 Ultrasonic sensor (for example: https://www.digikey.it/it/products/detail/adafruit-industries-llc/3942/9658069)
2. SR04 Sensor Case (https://www.tinkercad.com/things/69JTPE9g84N)
3. Cable gland PG9 (for example: https://www.amazon.it/gp/product/B07V9GK4R8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 )
4. 3-pole cable

SR04 3D Case is composed by 2 parts: the box and the cover...print it.

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

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

Connect the wires to the sensor.

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

Fix the cover with 4 small self-tapping screws

The sensor is ready for use.

The 2 holes on the sides of the box allow you to fix the sensor wherever you want!
