Updated Wind Sensor

Posted by Matthew Little on

This is a post to highlight all the changes and testing that has gone into the new design Wind Sensor Interface. I developed this sensor board to monitor different wind speed sensors (anemometers) and wind direction sensors (vanes). The main problem was that the wind speed changes rapidly and so any data-logging system needs to be powered up and recoding... Read more

Developing the Solar Soil Sensor

Posted by Matthew Little on

My houseplants have been dying due to a mixture of over and under watering. So I thought something to help stop that would be good. And even better if it's solar powered. I've been working with a solar powered ATTiny85 for the Solar 8 Ball and Solar Dice kits and thought I could use the same basic circuit to implement... Read more

Workshop Environmental Monitoring Project

Posted by Matthew Little on

I have built an environmental monitoring unit for my workshop. This measures: Air Temperature, Humidity & Pressure PM2.5 and PM10 Particulate values Radiation levels It shows the data on a small OLED screen. There is a large LED RGB display which changes colour if data goes above warning levels. This unit sends data to AdafruitIO via MQTT messages. This is all... Read more

Monitoring Radiation with the CheeseBoard

Posted by Matthew Little on

This post covers adding a radiation sensor (Geiger counter) to my environmental monitoring system.   A while ago I had purchased a NETIO  GC10 v2.4 Geiger Counter. This measures Beta and Gamma radiation and has a serial output, at 9600 baud. The unit was designed in the aftermath of the Fukushima disaster as a low cost way for monitoring radiation... Read more
