Waterproof DS18B20 probe at Adafruit

As luck would have it, about a week or two after building the DS18B20 temperature probe from scratch since I didn’t want to wait for it to ship from China, Adafruit has added a similar probe to their product lineup. The Adafruit probe looks very similar to the Arduino-Direct one, but Adafruit is US based …

DS18B20 Temperature Probe

Solder and heat shrink wires

Although the form factor for the DS18B20 1-Wire sensor boxes I built for the Easy Arduino 1-Wire Sensor Network are relatively small my friend thought an even smaller probe type version would be nice to have for using in places where the phone jack box would be too obtrusive. It would also be nice to …

First SMT solder job

SMT DS2438A

I am working on a new sensor for my 1-Wire network using the Maxim DS2438A, which is only available in the SOIC-8 package. I haven’t done any work with SMT devices up to this point, so this was first for me. I ordered a SOIC to DIP Adapter from Sparkfun to go with the DS2438A …

Easy Arduino 1-Wire Sensor Network

Arduino 1-Wire sensor network

A few months ago a friend of mine asked me if I could help him build a temperature monitoring solution for his home. After several failed attempts with various wireless temperature sensors/strategies I decided a wired solution was a better way to go. I built a solution based on an Arduino utilizing Maxim’s 1-Wire DS18B20 …
