Temp Sensor Module for Environmental Monitoring - DS18B20 1-Wire

About the print

This print is part of a larger project I am working on to implement Mycodo into my hydroponic garden. The goal is to have several modules that can connect independently, with ‘break out boxes’ for different sensors, outputs, etc. This is my temperature sensor breakout box.

This housing is just a hub that acts as a connection point for any sensors using a connection that can be run through a 3.5mm audio jack. I am using it as a 1-wire bus for 5 temperature sensors, with one port bringing in VCC/GND/DA from a Raspberry Pi or Arduino and the other 5 attaching to sensors. The housing has a connection point for the pull up resistor/terminal breakout board that comes with these sensors.
