简介:
N-CH4烟雾气体检测模组,是基于烟雾传感器MQ-2设计而成。可以直接连接单片机控制。通过电位器,用户可以设定气体报警浓度,单片机可以通过模组高低电平信号检测得到。另外通过一路模拟电路输出,用户还可以获得当前环境下,具体的甲烷气体浓度。
对液化气,天然气,城市煤气,烟雾有较好的灵敏度。具有长期的使用寿命和可靠的稳定性、快速的响应恢复特性。
The N-CH4 Gas Sensor Module is designed to allow a microcontroller to determine when a preset Methane gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires two I/O pins from the host microcontroller. The sensor module is mainly intended to provide a means of comparing methane sources and being able to set an alarm limit when the source becomes excessive.
规格:
应用领域:
适用学校传感器教学实验,适宜于液化气、丁烷、丙烷、甲烷、酒精、氢气、烟雾等监测装置。
