Submitted by jennajane on Fri, 04/08/2016 - 11:33am HideTool Concept Stage: Ready to Build Primary problem statement: I am a a farmer and I want a tool to to control temperature in my greenhouse because the commercially available products are expensive and limiting. Read more about this problem statement License: This work is licensed under a Creative Commons Attribution 4.0 International License (link is external). Description: This is the first stage of a collaborative build of greenhouse controller. The primary purpose of this controller is to operate two motors for roll-up sides through a relay box that was built during a workshop hosted by the CAPE in Quebec. The secondary purpose is to operate a heating system with the powerswitch tail available from adafruit.Add new comment HideDocumentation Documentation Wiki: Bill of materials Arduino uno, pro-min, mega $5-$50 ds18b20 temperature sensor with pull-up resistor (link is external) $15 CDN JW-100-M Male Crimp Pins and Housing (link is external) $15 CDN 610 Panel Mount 2.1mm DC barrel jack (link is external) $4 CDN 15-0298 Stereo Plug Solder Lugs 3.5mm (link is external) $1.30 CDN 70-534B 3.5mm Stereo Isolated Chassis Mount Jack (link is external) $4 CDN 1-2 762-ADA Cable Gland PG-7 size - 0.118" to 0.169" Cable Diameter - PG-7 (link is external) $2.80 CDN 63-ADA 9 VDC 1000mA regulated switching power adapter - UL (link is external) listed $10 CDN 22 AWG solid hookup wire.
