是否支持OSEPP MQ-3传感器？ [英] OSEPP MQ-3 Sensor supported?

问题描述

我正在检查是否有人对OSEPP MQ-3（酒精气体传感器）有任何经验，并从Rasp Pi 2获取传感器数据。 我把它设置在GPIO上并且没有运气从传感器读取任何数据，我也通过CP2102 uart-ttl桥尝试了
。 这不是一个独立的MQ-3传感器，因为它内置了集成调整和电阻，因此它应该即插即用。 任何有关对此设备进行故障排除的经验或想法都将受到赞赏。

I am checking to see if anyone has had any experience with the OSEPP MQ-3 (Alcohol gas sensor) and getting sensor data from it on a Rasp Pi 2.  I have it set up on the GPIO and have not had any luck reading any data from the sensor and I have tried it also via a CP2102 uart-ttl bridge.  This is not a standalone MQ-3 sensor as it has an integrated adjustment and resistors built in so that it should be plug and play.  Any experience or thoughts on troubleshooting this device would be appreciated.

推荐答案

根据数据表和源代码，传感器提供模拟值，因此您必须使用模拟数字转换器作为pi不包含一个

based on the datasheet and source code the sensor provide analog values so you would have to use an analog to digital converter as pi does not include one
