The DS18B20 and DS18S20 represents a very simple sensor. These Raspberry Pi sensors are addressed via the so-called 1-wire bus. An advantage is that many different 1-wire components can be connected in series and read out by a single GPIO. However, these modules can not measure additional information such as humidity and / or air pressure. The DS18B20 is particularly suitable for outdoor …
31/05/2018· If we analyze some kind of gas with a Raspberry Pi, we can do it very simple with sensors MQ, only we need to know in any case sensor obtained depending on the gases to be analyzed and ready, We see in this post how to connect and get the values. As usual, at the end we will keep the data in a MySQL database for viewing from Grafana!
In this research used two types of sensors, pH sensor and MQ-135 sensor to measure ammonia levels associated with Arduino microcontroller and Single Board Computer Raspberry. This research is also equipped with technology based on the Internet of Things. The measurement results will be displayed in the Smart Phone application. In this system will be kept pH value neutral (6,5 - 7,5). When ...
