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.

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

Where it fits my build
On Day 104 I pulled the roof wiring through the PVC route with fish tape and brought the cable groups into the van. I fitted plastic trim around the roof opening where the wires passed through.
I also finished the remaining light-wire connections, fitted the junction-box covers, joined the remaining PVC sections and tightened the metal ties around the route.

My build notes
This stage pulled together several earlier sessions of drilling boxes, fitting glands and arranging the roof hardware. The final cable entry was the point where all those separate roof routes met.
My notes show how much of the work was physical organization: pulling cables, keeping entry points accessible and closing boxes after the connections were finished.
The route into the van was a layout problem as much as a wiring task.
Alternative products
Two alternatives to compare
ELEGOO and WWZMDiB supply other HC-SR04 module packages, with different accessory and mounting-bracket assortments.
ELEGOO HC-SR04 Sensor Pack
These ultrasonic sensor boards use two round transducers and a four-pin header. The pack supplies several modules for electronic prototypes.
This pack supplies HC-SR04 ultrasonic distance-sensor boards with paired transducers. Header pins provide the power and signal connections for a prototype circuit.
