Prime1 High Resolution Infrared Methane (CH4) Sensor

Prime1 Infrared Methane Sensor CH4 Sensor Description and Operation
The Prime1 sensor uses the non-dispersive infrared method to detect the presence of hydrocarbon gases. Thesensor contains an infrared radiation source, a dual element custom infrared detector, a unique optical waveguide into which gas diffuses and internal ARM7 core microprocessor based electronics to provide a voltage output which is independent of the power supply polarity. The sensors can be configured to provide a pellistor format output, typically mid supply at zero with the voltage output increasing with respect to the detector pin by 100mV at range, or a linear voltage output, typically 0.4V - 2.0V over range with respect to the negative supply pin. In addition, the output can be read and the internal configuration can be accessed by a serial communications link.
