Abstract
A control body is coupleable with a cartridge to form an aerosol delivery device, with the cartridge being equipped with a heating element. The control body includes first and second positive conductors connectable with respectively a power supply and the heating element. The control body includes a series pull-up resistor and switch connected to and between the first and second positive conductors. A microprocessor is configured to operate the switch in a closed state in a standby mode in which the pull-up resistor causes a logical high level of voltage at the second positive conductor when the control body and cartridge are uncoupled, and in which the heating element is unpowered causes a logical low level of the voltage when the control body and cartridge are coupled. The microprocessor is configured to measure the voltage and control operation of functional element(s) of the aerosol delivery device based thereon.
