Thanks to ThingSpeak for allowing us to upload data and get real time graphs and Matlab analysis.
So far we have managed to upload temperature, humidity, and light levels to a ThingSpeak channel ( 212605 ). Details here…
We have 3 channels, the first (212605) is our main channel for this exercise, it is called Shelter Monitor:
Field 1: Temperature – Field 2: Humidity
This channel also shows a Google Gauge displaying temperature values.
The second channel (212968) calculates the average humidity using Matlab analysis:
Field 1: Average Humidity
The third channel (212950) calculates the Dew point, reading the values from channel 1, and performing the Matlab analysis:
Field 1: Dew Point
Channels 2 and 3 are programmed using TimeControl to trigger the analysis hourly.
Channel 1 receives data every minute, a median of 10 readings is calculated, therefore updates to the graph happen every 10 minutes.
