The Item in My Kit

I bought Smraza HC-SR04 Ultrasonic Sensor Kit as part of my camper van equipment.

The Smraza modules are among my electronics purchases for the van project. The diary photos here document my actual device-wiring work, with cable grouping and access to connection points central to that stage.

Comparing Sensor Boards with Their Mounting Accessories

  1. I pulled the roof cables through the PVC route with fish tape.
  2. I fitted plastic trim around the roof opening where the wires entered the van.
  3. I completed the remaining light connections, covered the boxes and joined the final conduit sections.

My Takeaway from This Job

The wiring diary shows how much of the work involved organizing devices and connections. These separate prototype kits share the HC-SR04 board format; Smraza adds brackets, while the other packs concentrate on the modules and their supplied accessories.

Product Details And Van-Build Uses

SpecificationProduct Detail
ModuleHC-SR04
Sensing FacePaired ultrasonic transducers
KitModules and mounting brackets

The two round transducers form the sensing face of each HC-SR04 board. A prototype layout needs to show that face, the bracket and the connecting leads together. Keep the exact module reference with the test project so a later enclosure can be measured around the same board. For a van electronics experiment, separate the proposed sensor position from any result: the module purchase and bracket layout do not by themselves establish a completed measurement system.

Questions from My Build

How Did I Pull the Roof Wiring Through?

My Roof Wiring and Devices Project Day 8 notes record using fish tape to pull wires through the PVC route.

What Do the Photographs Show?

They show the trimmed roof entry and the roof hardware at the end of that wiring session.
