Wireless Projects

Wireless sensors and a RaspberryPi open up a world of possibilities. The Internet Of Things (IOT) is phenomenon sweeping the world at this moment where everyday things (cars, homes, household appliances, plants) are being connected to the IOT where we can monitor, control and alert in ways not possible before.

RF communications can be a complex subject, but I have eliminated all the complexity by using pre-programmed devices that have the RF communication libraries already loaded. The components are plug and play ready to use (depending on the project soldering is required in some cases).  You do not need programming knowledge or know anything about radio communications or serial communications in order to do these projects. Although these projects do provide software to connect your wireless sensors to the PrivateEyePi system, you can use them for any wireless application you have in mind. 


1. Raspberry Pi RF Base Station Receiver 
  • RF Sender/Receiver
  • Simple communications sends and receives plain text 
  • Communicates to the Raspberry Pi through serial port communications
  • Data sent to the serial port from the Raspberry Pi is transmitted over the air
  • Data received over the air is sent to the serial port
  • No soldering required
  • More details here

Connect Base Station to Raspberry Pi

2. Multi Function RF Sensor
  • Multi function RF Sensor that can be used as a wireless switch or temperature sensor or both at the same time
  • Common uses for the wireless switch:
    • Reed switch for door, window and smoke detection
    • Wireless motion sernsor
    • Wireless water sensor
  • Built in temperature sensor (no soldering required)
  • Heavy duty case
  • Long lasting battery power (CR2032 3V) 
Examples of common wireless switches:

    Wireless Temperature Sensor         Wireless Door/Window Sensor             Wireless Water Sensor
   


Follow the following steps:
          1. Connect Base station receiver to Raspberry Pi
          2. Configure the serial port on the Raspberry Pi
          3. Test the Multi Sense Sensor
          4. Construct a wireless sensor:
            1. Wireless Temperature Sensor
            2. Wireless Switch
          5. Download and run the wireless software
