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.  You do not need to know anything about RF communications or serial communications in order to do these projects. Although these projects do provide software to connect your wireless sensors to the PrivateEyePi alarm system, you can use them for any wireless application you have in mind. 

Follow the following steps:
          1. Connect Base station receiver to Raspberry Pi
          2. Construct a wireless sensor:
            1. Wireless Temperature Sensor (10k Thermistor)
            2. Wireless Switch
            3. Wireless Temperature and Humidity Sensor (DHT22)
            4. Wireless motion sensor
            5. Wireless relay switch
            6. Wireless water sensor for flood detection
          3. Configure the serial port on the Raspberry Pi
          4. Download and run the wireless software
