Overview
BL841-KG is a general-purpose, miniaturized gas detection module. The module is equipped with a fuel cell type electrochemical button sensor, which not only has low power consumption, but also can effectively avoid the risk of leakage of traditional electrochemical sensors. In terms of circuit, the instrument amplifier, high-precision AD converter, etc., the detected gas concentration is converted into a digital signal, and the data transmission can be carried out through serial port, PWM and other signals, not only the signal is stable, but also a multiple choice.
Key Features
High temperature resistance, fast response, low power consumption, high precision, long life.
Applications
Vehicle lithium battery failure detection, smart home CO gas detection, portable carbon monoxide detector, etc.
