We are adding new tools to Big Hanna’s toolbox
We believe in making it easy for our operators to create the high-quality compost that Big Hanna is well known for. In addition to temperature sensors throughout the biological process it is now possible to monitor moisture in the mass inside the cylinder and humidity + CO2 in the air from the composter. The additional parameters will make it easier for our operators to control that the input has the correct moisture and that the biological process is well aerated. These parameters will naturally be logged and logfiles can be accessed onsite as well as through remote connection.
Facts:
CO2 sensor
The CO2 sensor (optional) measures the CO2 content in the air coming from the composter. In aerobic composting, the more oxygen that is available, the more carbon dioxide (CO2) produced, the less methane (CH4), and the more complete the decomposition. As biological activity progresses, the oxygen concentration falls, and CO2 concentration increases.
Moisture sensors
Moisture sensors (optional) are available for measuring moisture in the mass inside the cylinder and in the air from the cylinder.
The sensor measuring moisture in the mass inside the cylinder is measuring volumetric water content (VWC). Simply put this gives a value of appr. 0% if the sensor is in air and appr. 100% in saltwater as it calculates conductivity. Recommended value is 40-70%.
The sensor measuring humidity in the airflow from the composter is measuring relative humidity (rH). Relative humidity depends on air pressure and temperature.
