Abstract

The paper deals with measurement of concentration of highly toxic carbon monoxide within the space of waste rock storage. This purpose gave origin to creation of units with integrated sensors of carbon monoxide that transmit measured concentration by means of wireless IQRF technology. The need of decreased power consumption implicated choice of electrochemical CO sensor connected to a special wireless technology named IQRF, working at 868 MHz frequency. Concentration is measured at two locations within waste rock dump. The paper analyzes consumption of energy spent on this type of measurement and it evaluates assumed endurance for battery-operated mode. Concentration of CO is sent to IQRF-AO converter that transfer the measured value to voltage level by means of double-channel DAC converter. This voltage is then brought to the inputs of telemetry unit that transmits the values of CO and other measured signals to a supervisor dispatching center.
