1. A system for detecting the presence of a gas, comprising:

  • a sensor portion, having a sensor processor, for sensing a target gas and providing signals indicative of the gas;

    a transmitter portion for transmitting information received from the sensor portion to a network, the transmitter portion including a transmitter processor;

    a variable voltage power supply associated with the transmitter portion and configured to supply voltage from the transmitter portion to the sensor portion for operation of a sensor of the sensor portion, the variable voltage power supply including a plurality of potentiometers to provide coarse and fine adjustment of the voltage supplied to the sensor portion; and

    a barrier circuit for limiting at least one of current, voltage and power to the sensor portion;

    the sensor processor being configured to;

    determine a voltage received from the transmitter portion; and

    communicate the determined voltage to the transmitter portion; and

    the transmitter processor being configured to manipulate at least one of the plurality of potentiometers to adjust the voltage supplied to the sensor portion for operation of the sensor based on the determined voltage.
