Read More…The v2 board has improved echo handling and support for 3.3v controllers This original type is now reduced to clear. Stock are units a customer exchanged for the v2 board (he needed 3.3v), so headers are pre-installed. I have retested these before returning to stock.
This module - and the associated library - allow you to connect eight HC-SR04 ultrasonic range sensors to an Arduino using the I2C bus and one hardware interrupt pin.
I wanted more sensors on my robot to help it navigate. I'm too cheap to buy a mega board with enough pins or smarter sensors that need less pins.
The library handles all the timing, and the hardware interrupts provide surprisingly high accuracy. Each unit is individually tested using an Arduino shield based test-bed and ships with separate pin headers.
I am stocking some of the sensors and cables too, so you can get them at the same time. These are batch tested to verify that they are not the type with the echo-lock problem.
Please check out the Hackaday documentation and the github library for more info.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I've been building and fixing things all my life and in my day job I build datacenter installations and watch over thousands of Linux servers. For fun I make things like old British motorcycles, Daleks and random electronics. I've invented some things along the way that I needed and weren't available (or I was too cheap to buy), and I'll be sharing some of these items in my Tindie store.
