Add-on Board

Soldering the resistor to between the power and data lines of the sensor cable can be a bit tricky. Especially if you want to connect more than one sensor to your Pi (as you’d solder the resistor to two power and two data lines!).

To make things easier, I designed a (very) simple board. It lets you connect up to five sensors, all you need to do is crimp the sensor cables with the appropriate connector.

I have a limited number of boards available for FREE, get in touch via Gitter or Twitter (DM @jamanifin) if you're interested.

The raw board

Basic PCB

Add up to five sensors with simple push-on type connectors. You just need to crimp them

Using right angled headers

Adding Headers

Using right angled headers on the Pi means you can still use the remaining GPIO pins

Soldering directly onto the Pi Zero

Sandwich!

Soldering the three pins directly to the add-on board and using the right angled headers keeps the whole thing small

For the temperature-machine in my lounge, I mounted it behind my TV and added some Pimoroni Blinkt! LEDs for ambient lighting.
