The Skyeaglee SK/MIC-500 is a professional-grade gas sensor module designed specifically for the continuous monitoring of Liquefied Petroleum Gas (LPG). Built with an advanced catalytic combustion sensor, it delivers rapid, accurate, and stable detection within the 0-100% LEL range. Its compact size and lightweight design make it an ideal choice for system integrators, OEM equipment, and industrial monitoring systems.

Engineered for industrial reliability, this module simplifies complex gas detection requirements:
Simultaneous Dual Output: Offers both analog (4~20mA) and digital (RS485 Modbus RTU) signal outputs simultaneously, providing maximum flexibility for MCU or PLC integration.
Zero-Calibration Ready: Factory precise calibration ensures the device is ready to use immediately upon installation, eliminating the need for further secondary calibration.
High Reliability: Features a built-in zero-point fine-tuning function and data recovery to prevent issues caused by accidental operations.
Low Power Consumption: Operates with a working current of $\le50mA$, making it suitable for portable power supplies and remote monitoring equipment like UAVs.

The Skyeaglee LPG sensor module is manufactured using precise circuit design and high-quality materials to ensure durability in harsh environments.

A: No. The SK/MIC-500 undergoes factory precise calibration. It is designed for simple "plug-and-play" integration, meaning there is no need for further calibration before initial use.
A: The RS485 interface adopts the standard Modbus RTU protocol (Baud rate: 9600, N, 8, 1). It also outputs a 4-20mA analog signal simultaneously.
A: Yes. The robust sensor body is constructed from high-quality Aluminum alloy and ABS, featuring an IP66 protection rating. It operates reliably in temperatures ranging from -20°C to 50°C.
A: This module focuses on precise data acquisition, storing configurable low and high alarm values in its registers (such as 20% and 50% respectively) for your host system to read via Modbus. It outputs the signal directly for your MCU or PLC to trigger external safety systems.
