The Leaf Wetness Sensor is a Small circuit board this is mounted so it can be adjusted to different angles. The leaf wetness sensor is made up of two parts a Hobby board moisture circuit board And the leaf sensor







Solar Radiation
Solar radiation sensor, The Photodiode has been extended from the circuit board , and mounted in a table tennis ball this will protect the photodiode and allow enough light for the device to work the Ping Pong Ball is glued to a plastic tube ,  then mounted in to a waterproof box and sealed with sealant

Barometer
Hobby board barometer It reads pressure from 28-32 inHg (948-1083 mb). It's resolution is 0.01 inHg (0.34 mb).

Temp/Humidity
Instruments in the small Stevenson screen is a set of Sheathed ordinary Hygrometer . Met Office pattern (BS692). )  a standard minimum maximum temperature sensor, there is a small fan at the bottom this helps with air circulation











My first weather station was an Oregon scientific wireless model WMR928NX the manufacturers have stopped production on this model and now  offering a WMR200 - Next Generation Weather Station as a replacement, I decided to go for a Proffessional 1 wire weather station system.
The following sensors were supplied by Hobby Boards ( Power injector,solar radiation sensor, barometer, out door temperature/humidity, Leaf wet sensor, soil moisture module using a Watermark sensor (granular matrix sensor), concrete temperature sensor, soil temperature sensor@2 inches, rain gauge, snow sensor using a hobby board humidity module connected to a LV-MaxSonar®-EZ™ Sensor, Cloud sensor mod using a temperature sensor, Dual Counter mod rain switch connected to a Rain Tracker Rain Gage - Model RG-10, the wind instruments were supplied by Inspeed and connected to a hobby board Anemometer Controller Board, rain duration sensor is a humidity module which is connected to a sensing plate

There are several traditional instruments which we use for calibration purposes, we have lightning radar system which detects storms over Europe, we are also monitoring earthquakes around the world using a HS-3 SEISMOMETER, to keep our weather station time clock accurate we use a GPS system which synchronises the weather computer.

consists of a solid stem thermometer fitted into a transparent glass sheath. Each depth is established by inserting a steel tube into the ground, and lowering the thermometer by the chain down into the tube. The thermometer bulb is embedded in paraffin wax to give a slow response time enabling it to be withdrawn to take readings

UV Sensor mounted in a waterproof box
Rain gauge set to tip at  0.2mm this rain gauge is connected to a 1 wire counter,inside the rain gauge there is a heater and a thermostat which is designed to melt snow, 
Rain duration sensor set to detect moisture from 0.001mm this device is connected to a hobby board counter module, as soon as any droplets of rain hit the lens weather display indicates very light mist, this device also is used as a rain duration sensor

Soil moisture sensor consists of a hobby board moisture module which is connected to a watermark sensing module
The cloud sensor consists of a one wire temperature sensor which is surrounded by insulation on the top of the temperature chip is a black metal disc,this is position so it is pointing at the sky weather display software works out the  sky condition based on the temperature differential from the Air temperature,and cloud sensor temperature
In this solar radiation screen there is a temperature and humidity module the temperature sensing chip and humidity sensing aliment have been Extended from the circuit board to form  two probes the humidity probe also has a protective nylon mesh cap this improved the response of the Humidity sensor there is a fan mounted at the bottom which is drawing air through the top and down over the sensors
