Overview
BSV481 is a flame detection module based on the infrared and ultraviolet principle. It uses pyroelectric sensors, ultraviolet sensor and high-performance microprocessors. It is a flame detection module designed through the combination of different sensors. It has a built-in high-speed microcontroller to collect sensor signals and use reliable and efficient algorithms to effectively judge the fire. The interface is simple and the output signals are complete. Simply design a simple power circuit and relay circuit to develop a complete flame detector, shortening the product development cycle.
Key Features
- Adopt large field of view angle, high detection rate, and low microphone effect sensor;
- The ultraviolet sensor has a sun blind type, effectively reducing sunlight interference;
- Combining multiple combustion substances to establish a data model with low false alarm rate;
- M4 core high-speed microcontroller with fast response and low power consumption.
Applications
Space industry, storage facilities, printing industry, paint manufacturing, pharmaceutical industry, power generation facilities, machinery and automobile manufacturing, petroleum and petrochemical industry, etc.
