This is an attachment for a standard blind cord for to use as a magnetic end-stop sensor with the Alexa controlled automatic blind controller.
The Blind Controller currently operates up and down blind movements based on calibrated times. This works fine most of the time but does require some patience to set-up and over time can drift resulting in the blinds over or under shooting their intended end point.
To solve this I have been working on a magnetic sensor that attaches to the accessory slot and requires only two small attachments to either end of the blind cord. As well as the 3D-printed attachment you will also need the following:
Magnetic Sensor Module:Magnetic Sensor Module - SODIAL(R)Mini Detection Sensor Module for Arduino Magnetic 3.3-5V
6mm Diameter x 1mm thick Magnets x 12:Magnet Expert 6mm dia x 1mm N35 Neodymium Easypeel Adhesive Magnet - 0.33kg Pull (North) (Pack of 20)
Male 5-5x2.1mm DC Jack:MagiDeal 5Pairs 12V 5.5x2.1mm Male + Female DC Power Socket Jack Connector Cable
See my website http://www.cabuu.com for more details
A demonstration of the sensor in action is available here:https://youtu.be/W8R-BSzm8r0
