1. A respiratory humidification system comprising:
a hardware controller configured to be in communication with a first heater wire in a first segment of an inspiratory limb and with a second heater wire in a second segment of the inspiratory limb, wherein the first and second heater wires are electrically coupled within the inspiratory limb and configured to heat respiratory gases passing through the inspiratory limb, the first heater wire forming a first heater circuit and the first and second heater wires forming a second heater circuit;
an intermediate connector configured to couple the first and second segments of the inspiratory limb, the intermediate connector having a connector circuit configured to electrically connect the first and second heater wires;
wherein the hardware controller is configured to be in communication with at least one sensor for measuring a surface temperature of the inspiratory limb.
