MicroHTR (Part 6)

Part 1, 2, 3, 4, 5, 6, 7, 8 The heart of MicroHTR is a PID controller which is coded within the PlainPID library. Some refinements have been brought to this library in order to make it easier to use and as versatile as possible. It now features a pretty robust anti-windup function which prevents large overshoots while heating (or […]

Pending publications

Summer is over. Apparently a lazy period of time, in reality, time for retrospection, thoughts and projects making ! For me it has also been a time for getting inspiration from various European places, other ways of living, travelling, enjoying arts and culture. Whoever will identify this place will get… my highest consideration ! [Mail] […]

Measuring temperatures with TMP03/04 (Part 6)

Part 1, 2, 3, 4, 5, 6, 7, 8 This post could be nammed “Ooops of the day”… I recently added the PlainTMP0x library in an application which is running over very long period of times. In its previous version, the code would periodically send an error instead of a valid temperature. As this periodicity was very long (days), it was […]

Tips and Tricks (16)

Previous Tip and Trick Few words about the Adafruit thermocouple module. This nice little module features a couple of smart ideas: Use a fully integrated driver solution which outputs data on a SPI port (MAX31855) Any thermocouple assembly will fit on the header  (as long as it is a K type) 5V / 3.3V compliant […]

SHTx Temperature and Humidity Sensor (Part 1)

Part 1, 2, 3 I introduced the temperature and humidity sensors from SENSRION a couple a months ago [link to this post], and I recently decided to use one of them for building a sensor which would aggregate multiple physical measurements. For the sake of saving time, I ordered the PARALAX module which is handy and has a […]

MicroHTR (Part 2)

Part 1, 2, 3, 4, 5, 6, 7, 8 PID is probably one of the most popular type of process controller. You may find many papers on the net describing the origins this system. I can read that PID controllers were developed in automatic ship steering. While the PID controller proved higher performances than helmsmen […]

MicroHTR (Part 1)

Part 1, 2, 3, 4, 5, 6, 7, 8 MicroHTR stands for Micro heater project. This is a pending project for which I was unhappy with the information and code found on the web. Finally I decided to build a simple prototype in order to evaluate my draft PID code from which the following results […]

Measuring temperatures with TMP03/04 (Part 5)

Part 1, 2, 3, 4, 5, 6, 7, 8 And here is an example of use of the library /* PlainTEMP01_01.pde is an example of use of PlainTMP library, which reads temperatures from AD TMP03/04 and TMP05/06 sensors Copyright (C) 2010 Didier Longueville This program is free software: you can redistribute it and/or modify it under the terms of the […]

Measuring temperatures with TMP03/04 (Part 4)

Part 1, 2, 3, 4, 5, 6, 7, 8 Here are the lastest developments in the library (PlainTMP) which handles the TMP0x series temperature sensors from Analog Devices. The core function performs temperature measurement on TMP03, TMP04, TMP05 and TMP06 ratiometric sensors. The last two ones must be configured in continuous measurement mode (Pin 2 is left floating). The options […]

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 […]
