(1) Processor Setup
- Use Arduino Mega to interface to the sensors (more IO lines, a little more capable system than the Uno)
- Use Prototyping board on top of Mega for interface to the sensors
(2) Solar Radiation
- Solar Radiation sensor based on use of TSL2561 Lux Sensor from Adafruit (TSL2561)
- Solar Radiation sensor will need to be put behind a white painted glass surface
- Solar Radiation sensor uses I2C bus, read by Mega
(3) UV Index
- UV Index sensor based on use of SI1145 UV Sensor from Adafruit (SI1145)
- UV Index sensor will need to be put behind a clear glass pane, plastic pane will inhibit the UV from passing to the sensor
- UV Index sensor uses I2C bus, read by Mega
(4) Pollen Count
- Pollen Count sensor based on use of SCM GP2Y1010AU0 bought from Happy Store (B00GET4KR0)
- Pollen Count sensor actually counts density of particles greater than 2.5 um
- Pollen Count sensor puts out a voltage which will need to be read by Mega
(5) Connection to Weather Station RPi
- Connection to Weather Station RPi done through an Addicore nRF24L01 2.4GHz wireless transceiver (B00E594ZX0), one on the Mega and one on the Weather Station RPi
- Will require python script on Weather Station RPi to read values from Addicore transceiver
- Will require code on Mega to transmit all three values at a regular interval
(6) Housing for Sensors
- Housing for Sensors should be based off of Solar Radiation shield (Radiation-Shielding-7714)
- Power comes up through the bottom of the shield
- Need two holes cut into the top; one for white painted glass for solar radiation and one for glass for UV index
