The automatic weather station at Pitsford Hall captures data on temperature, humidity, rainfall, sunshine, wind speed and direction, and barometric pressure every 15 minutes. If the station has not uploaded data for some time, please check our status report for an explanation.
Both hardware and software are manufactured by Instromet Ltd .
The station also benefits from having a Boltek lightning detection system which can provide an early warning of approaching thunderstorms across the county as well as a fully automated email messaging service (TSentry). You can dial up the automatic weather station for the latest weather data on the move (07807 551391) as well as receive SMS text messages.
Sensor: rotating cups using a Hall effect sensor and wind vane.
Sunshine Duration Sensor: within glass dome; comparison between shade and sensor produces pulse every 36 sec when ratio exceeds a fixed value.
Rainfall Sensor: mounted in an aerodynamically shaped moulding to reduce effects of wind. The rain is collected by an 80 mm diameter funnel which passes drips through an infrared beam and counts drops.
Air Temperature Sensor:precision NTC thermistor within a radiation shield. Humidity is determined algorithmically by comparison with a wet bulb sensor.
Pressure Sensor: electronic barometric pressure sensor, mounted within data logger.
