Bat-mail: Email alerts with the Bat Detector

Posted by Matthew Little on

This post covers a bit of an experiment I tried using both our bat listener kit and the cheeseboard (an ESP8266 development board). I wanted to make a unit that would send me an email whenever a bat was detected in my garden. This would be based upon the ESP8266 and monitor the output from the bat listener kit we sell. This was just a bit of fun, but might have some useful applications for remote monitoring... I basically just needed to connect the micro-controller output from the bat listener to a GPIO pin on the ESP8266. I needed to...

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...

CheeseBoard: Adding an Air Quality Sensors

Posted by Matthew Little on

I've been interested in environmental sensing for a long time - mainly for monitoring renewable energy sources. I've been collecting interesting sensors for a while and one of those was a "Nova PM Sensor SDS011 High Precision Laser PM2.5 Air Quality Detection Sensor" (mine came from Bang Good, but available in lots of places). This is quite a large sensor with a fan to control air flow over a laser detection sensor. The datasheet is available here.     The data is obtainable via a digital output (pulses when particles are detected) or via a serial connection (at a default of...
