Prototyping a Wildlife Camera

Posted by Matthew Little on

This blog post covers the main design choices and prototyping stages from developing a wildlife camera unit. I had seen the ESP32-CAM, which is based on the ESP32 wifi module. It's incredibly low cost and does some amazing things (including face recognition) with the example code other people have written. I got hold of a couple of samples and thought they would be perfect for a low-cost, solar powered wildlife camera which might be useful in lots of applications. This post covers the work I did on firmware design and PCB design for the unit. I am hoping to have...

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 based on the 'Cheeseboard', which is an ESP8266 development board, based upon the NodeMCU. Pretty pleased with the end result. You can view my data here on Adafruit IO dashboard. (Please note: there are a few blips in the data...

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 levels. Some more links to this unit are here: Manual for GC10 NetIO Unit (assembly in English) NetIO Shop (currently sold out!) GC10 (aka 'Kinoko Geiger') users group (mainly Japanese) Review of the unit (youTube) I wanted to include this sensor...
