Measuring temperatures with TMP03/04 (Part 3)

Part 1, 2, 3, 4, 5, 6, 7, 8 Here are some measurements performed by two TMP03 sensors. One is attached to a dissipator the other one is not. Acquisition parameters are: 1 cycle per second, 2 channels, no averaging, resolution 0.05°C We can make two major observations from these plots: The top one (free standing sensor) shows a higher […]

Measuring temperatures with TMP03/04 (Part 2)

Part 1, 2, 3, 4, 5, 6, 7, 8 Now that we know how the TMP03/04 sensor works, let’s try to run it with Arduino. My first intuition drove me to write some code which would use interrupts (attachInterrupt() function). The first tests were alright, but I very quiclky tried to add some protections e.g. broken data link to the […]

Measuring temperatures with TMP03/04 (Part 1)

Part 1, 2, 3, 4, 5, 6, 7, 8 TMP03/04 is a temperature sensor from Analog Device. Amongst all types of temperature sensors, this one has some very interesting properties: the temperature reading is not based on voltage ouput or impedance changes. The IC produces a digital signal wich cyclic ratio depends on temperature changes. The on time (T1) is […]

Hello world!

Welcome to Arduinoos. Watch out the fresh paint, lacks and bugs in this new blog. Many fancy papers will be issued soon.
