ATtiny2313 Based Thermostat Final Update

Finally, I had some time to do video on my thermostat project, and to upload all the project files.

ATtiny2313 – Based Thermostat Project Update #2

First fully working revision of firmware is finished, which takes all 2k of ATtiny2313′s memory. I wrote it in C, and I wanted to implement some other functionality, but unfortunately I’m out of space(of course if I would want to, I can put there ATtiny4313, which is identical to ATtiny2313, but has 4k of memory). …

UNI-T UT325 Thermometer Teardown

In the review of this thermometer I said that it was a weird Chinese product. And here’s why: despite of the poor firmware and software functionality it has pretty interesting and very “hackable” innards. Let’s begin..

UNI-T UT325 Thermometer Review

Very often in electronics you would need to measure temperature, not just in one spot, but simultaneously in two or more spots. And log that measurements, so that you can plot temperature change over time. Also, differential temperature measurements could be extremely useful in some cases, especially for thermal design of electronic projects. So, the …

ATtiny2313 – Based Thermostat Project (part 3)

ATtiny2313 – Based thermostat project update. I wrote a small test firmware for it to test if everything is wired up the right way and to test it’s current consumption. And it turns out that there were some mistakes.. Also it’s current consumption is well below 150mA that I was expecting.

ATtiny2313 – Based Thermostat Project (part 2)

So I’ve came back to my ATtiny2313 – based thermostat project, that I’ve started to work on some time ago. And today I have assembled a first prototype (actually I only need a couple of these). If you haven’t seen video I’ve made on this project, you can watch it here: Part1 Video. It’s based …

ATtiny2313 – Based Thermostat Project (part1)

My parents growing their own organic food and they asked me to deal with winter temperatures problem in the storage room. It gets really cold here, in Ukraine. Some winters have even lower temperatures than -30°C (-22°F). So right now I designing a simple thermostat for keeping temperature at about 5-7 degrees C above zero. …

Interfacing Microcontrollers: Temperature Sensors

One of the most often things you need to do in electronics is to measure temperature. Even a simplest device might need an over-temperature protection. In this temperature sensors overview video you’ll find out about most common types of temperature sensors, their main characteristics and usual ways of connecting those sensors to microcontroller. I’ll make …
