Creating a Smart Water Sensor with the ESP32 Thing

Over the Christmas break, my parents were out of town to celebrate the holidays. When they came back, they saw something every homeowner fears – a flooded basement. In a basement, there are pipes that collect water from around the foundation and bring it into the sump pit, which pumps it out away from the house. When the sump pump fails, water has no way to leave the basement and it floods. I recently bough ...

A development board for the STM32F042

It’s been a while since I posted a new article, a delay at least partly due to me herniating a disc in my neck which left me completely unable to look downwards for any length of time and as you’ll know all too well you can’t work on circuit boards without peering down at them. Look after your neck and back folks, and I mean that seriously. Well I’m back now and I’ve got a lot of ideas for articles spinning ...
