Testing the TR-EVO-60M-I2C rangefinder

By martinm, in Reviews, february 23,2024.

More or less by chance, we came across the TR-EVO-60M-I2C rangefinder manufactured by TeraBee. It promises a detection distance of 0.5 to 60 meters with a viewing angle of 2°. All this in the volume of a 3cm cube with an I2C and serial interface. At around 100 CHF apiece, we couldn't resist buying one to play with.

Ten years ago, we published a post showing how to use the Yocto-milliVolt-Rx-BNC with a pH probe to digitally extract measures. Of course, the 2014 module still works today, but in the meantime we've released a few tools which make using it even easier. So here's an update to this post...

Having successfully operated WaveShare's LCD1602-RGB display with a Yocto-I2C, we wondered if we could use the Yocto-I2C's built-in job system to read values from an I2C sensor and display them directly on the display without the intervention of a USB host. In theory, it's feasible; in practice, it's rather complicated, but interesting.
