The most important process in manufacturing reliable residential gas alarms is adjusting the alarm point. Calibration is a complicated and time-consuming process that also requires a substantial investment in calibration equipment. By
eliminating the costly calibration process, this module enables users to easily and simply manufacture residential LP gas alarms. Figaro has taken the complexity out of designing a gas detector circuit by providing users with a temperature compensation circuit that combines a built-in thermistor and individually adjusted load resistor together with Figaro’s low-power LP gas sensor.
