IN DEVELOPMENT
MIPEX 1S [C₃H₈] is an ultra-low power NDIR sensor designed for accurate propane detection in compact and portable gas detectors. With a typical current consumption below 65 µA and a fast T90 response time of 10 seconds, it enables years of autonomous operation in industrial safety applications.
MIPEX 1S [C₃H₈] is a compact NDIR sensor designed for reliable and energy-efficient detection of propane in portable gas detectors. It features an average current consumption of less than 65 μA, supporting extended autonomous operation from a single battery. With its ultra-compact size of 19.9×19.9×10 mm, the sensor is ideal for integration into space-constrained designs.
The supply voltage range of 2.7 V to 5.0 V offers flexibility for integration into various low-power systems. The sensor uses dual-wavelength LED technology to eliminate interference from humidity, temperature, and contamination — delivering stable performance in harsh conditions.
