50 of the most important Raspberry Pi Sensors and Components

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 ...

MQ-131 Module Ozone Gas Detection Ozone Sensor Module

MQ131 Ozone Gas Sensor Module is a compact board based on the MQ-131 sensor. It is equipped with a very wide range sensitivity to ozone which able to detect ozone concentration up to (10~1000ppb) in ambient air. The tin dioxide (SnO2) is the sensor's sensitive material, has a low conductivity (high resistance) in a clean air environment, and react really good in a presence of ozone. Thus ...

How To Measure Particulate Matter With a Raspberry Pi ...

Whoever chooses a Raspberry Pi Zero W needs an adapter cable to a standard USB port, because the Zero has only Micro-USB. The sensor is best purchased at Aliexpress. It’s about $17–20 there. The sensor comes with a USB adapter for the serial interface. Installation. For our Raspberry Pi we download the corresponding Raspbian Lite Image and write it on the Micro-SD card. This is …

MQ131 ozone sensor -

This breakout for the MQ131 sensor responds to the presence of ozone in the air. As the ozone concentration increases, the resistance changes and the ozone concentration can be measured by measuring the analogue output voltage. The sensor is of good precision and is normally used in ozone concentration detectors. There is a 3362 potentiometer on the board with which the digital signal ...

MQ 131 when detecting ozone - Sensors - Arduino Forum

· Hi, There is two ways of using the MQ131: - directly the sensor itself (bare / naked sensor) - via a module I used to have a module and I remove the sensor from the module because the documentation doesn’t exist. The two important things are: 1. You have to preheat the sensor for 48h at 5V to have consistent result. 2. In order to compute the ppm/ppb, you have to calculate the Rs/R0 and ...
