Arduino Temperature logger
By working with a high pressure pump I noticed that it was getting hot. Few tests with and without housing indicated that the temperature was increasing more than expected. Therefore I decided that a temperature logger is required.
In this small project I added different temperature sensors together to measure the temperature of a high pressure pump, ambient and the water that was passing the pump. I decided to use standard off the shelf boards for fast implementation.
Obtain necessary temperature sensors
Hardware build up
Logger software writing
Python data analytics software writing
This project had three parts. First, was the hardware build up. I had to measure lab ambient, pump housing internal, water and pump temperature. Additionally I was tracking when the pump was ON or OFF. All the data was logged with an Arduino on a SD-card. In order to be able to know if the logger is working I added a simple screen.
The second part was the logger software. I programmed the logger to log all the measured values after every second. The third part was having a script that could use the logged data. I chose Python for that and it prints out a nice html graph for a good visual overview.
The logger and its complementing software worked as intended. At the beginning I didn't have the screen and then it was difficult to say how high the temperatures were. Thus, the screen was added.
