Introduction: Voice Controlled Hospital Bed by Wifi

For galore people with significant mobility impairment, the function of sitting up, upbringin the feet operating theatre dynamical the height of a infirmary bed provides comfort throughout the night for sleeping and may even allow for greater independence. For myself, as an individual with a spinal cord injury who became paralyzed, I bet connected the functions of the hospital bed all day. But sometimes it can be hard to obtain the control for the bed since I cannot feel my hands, move my fingers or move my arms under the blankets. Given the infirmary bed is successful up of simple switches I figured why non use an low-level like Google Home base or Alexa to curb the bon. This instructable builds off this project. We retain the original function of the controller so no bed function is lost or if power goes out surgery the Wi-Fi down nothing changes. It sporty gives control by Wisconsin-Fi too.

I started with a photon spec for Wi-Fi operate and six relays for the six functions of the bang (head, head down feather, feet up, feet down, untouched bed up, high bed down). Since then we have refined it and latterly sent out and got PCBs fictional to name the device more robust and start making a handful of them for others in the profession who could also benefit from such a externalise.

As a cofounder of AbikityHacks.org, myself(Drew McPherson), Francisco, Jason, Mimi, and Jefferson have all worked on it present and there at our meetups. If this is something that could be useful for you and you'd like to try it get us know and we could send incomparable to you.

Supplies

  1. Photon Particle - Tie in
  2. Relay Boards or homogeneous-Department of State relays as used here (Digi-Key Part Number1835-1218-ND)
  3. rj45 operating theatre rj 50 cable (with testing we actually discovered that the RJ-45 cable television service also worked)
  4. rj4/50 female socet
  5. power suply

Step 1: Understanding the Bed

First off we have to empathize that there's the six switches or fleeting push buttons within the controller, two for each direction of the motors that drive the feet, the head, and the overall seam. This control uses in RJ 50, 10 stick connector to feed into the controller board every bit pictured in the white cable.

Maltreat 2: Wiring

Higher up you can see the circuit diagrams for the PCB we had made-up. You can also see the relay board which you could use to repeat the envision. As you can see by the circuit diagram the ii RJ 45 connectors are always connected retaining the daring function of the restrainer. It is worthy noting that the logic signal the controller delivers is 35 V at nearly 100 mA. We designed the circuit under the assumption we did not have accession to the internal ground of the drive controller in the bed thus fully analytic switching with the solid relays. However if an RJ 50 cable is used there is access to ground so in future iterations we may switch to that.

Step 4: IFTTT

  1. First you have to make an account
  2. next select make operating room my applets from the dropdown from your profile picture
  3. click "this" and hunt google helper and inter triggers and save
  4. next click "that" and hunt particle- will rich person to setup with particle account first sentence
  5. select function and input

Step 5: Code Integration

The computer code and execution was inspired past the https://www.instructables.com/id/Google-Home-Ceiling-Fan-Control-With-Particle-Phot/ by JimenaI3.

We used if and so past that to send the control to our Google helper and vice versa.
