An open source CO2 monitoring project from Roving Dynamics: The project described below uses a MH-Z16 or MH-Z19 CO2 sensor and a DHT-22 (or DHT-11 if less accuracy is required) to measure the Temperature and Humidity. It has a 4 line by 20 character LCD Display to show the current readings and status, a warning alarm […]
Arduino Geiger–Müller counter with LCD display
https://www.electronics-lab.com/arduino-geiger-muller-counter-lcd-display/
Bob tipped us with his latest project. It’s a custom Arduino shield able to communicate with a Geiger-Muller counter and display data on a LCD display. The data are displayed in two layouts: bar graph of the pulses in one minute interval and histogram of the gathered data. In the previous posts I’ve described a […]
