Using #Twatch as ICelsius wireless bbq thermometer monitor

Daniel use the #twatch as a monitor for his ICelsius wireless thermometer: Finally I found a purpose for my twatch. I use it as a monitor for my iclesius wireless thermometer. So I wrote a quick and dirty python script which works as a relay between the icelsius and the twatch. The icelsius periodically broadcast the […]

$2 DIY compost thermometer build

afraser-kruck wrote this instructable detailing his DIY compost thermometer build: Here are some basic instructions on how to build a $2 compost thermometer using readily available supplies. It looks crappy (in a good rustic kind of way), but works great and uses few materials. You really don’t need to read this… I like this design because it’s […]

A digital thermometer hygrometer with analog displays

Kerry Wong writes: In this post, I will show you yet another thermometer/hygrometer build. But instead of using an LCD or 7 segment display for the output, I decided to go retro, using two “needles” to display the temperature and humidity readings instead. And to make the project more fun, I did not use analog […]

DIY indoor thermometer and moisture meter

Raj designed an open hardware DIY indoor thermometer and moisture meter. It’s based on the PIC16F688 coupled with the DH11 temperature and humidity sensor. The 7-segment display has auto brightness correction depending on the lighting conditions. This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on […]

Adding a thermometer to your digital multimeter

Reading ambient temp is useful in electronics, and reading it from your handy multimeter is even better. Raj added a thermometer feature to his DMM, by hard-wiring it into the case. He used an LM35 analog temperature sensor and a slide switch connected to the multimeter inputs. You just flip the knob to the 200mV […]

Atmega8 based thermometer build

Andrianakis Haris writes: This is a thermometer I designed for my room, built in a small pack and easy to control. Some basic components used: Atmega8, LM35 for inside temp sensing and DHT-11 for outside temp & humidity sensing. The hardware is designed on a way so that the PCB can be wall mounted. At […]
