Sensor Review/Experiments

Problem: current motion sensor is intermittently affected by EMI from a near by device (WiFi enabled camera).

Scope: to find a motion sensor that will be invoked by EMI (WiFi, Bluetooth, 4/5G etc)

Sensor 1
  • Structure: 2 parts (Wireless sensor + 110v Plug)
  • Type: PIR (Passive InfaRed
  • Protocol: Wireless bluetooth
  • Cost: $24

 

  • Pros
    • Solid state and simple 
    • 110v feature already integrated
  • Cons
    • Each unit must be individually bluetooth paired 
    • The pairing process was cumbersome to operate 
    • Units must be physically label per pair
    • There is no way to adjust the time to 30 seconds
