DHT Sensor Comparison

Open chart.html to visualize the CSV data in serial.csv. It is also hosted on GitHub pages.

Data is from three sensors connected to an Arduino Sensor Shield, which is connected to a LinkIt One. Goal was to compare two DHT11 sensors with a DHT22 sensor. Test ran for approximately 10 hours connected to my MacBook Pro, which logged the results from the serial port.

Code for testing is in test.ino. This code relies on my fork of the Adafruit DHT Sensor Library.

Serial logging code is in read.rb. The serialport gem must be installed to use it.
