MEMS Hydrogen Sensor for Lithium Battery Thermal Runaway

MEMS Hydrogen Sensor for Lithium Battery Thermal Runaway

Rainbow Technology's Hydrogen H2 gas sensor module based on MEMS gas sensor is used to test the content of H2 gas in the ambient air. The test data is communicated through I2C and UART interfaces.
MEMS hydrogen sensors are commonly used for detecting hydrogen gas in various applications, particularly in lithium battery systems where hydrogen can be released during thermal runaway. These hydrogen sensors help enhance the safety and reliability of lithium-ion battery systems by detecting hydrogen gas emissions early, which is a key indicator of thermal runaway.
