MQ2 Smoke Sensor Circuit Built with a Raspberry Pi. In this project, we will go over how to build a smoke sensor circuit with a Raspberry Pi. The smoke sensor we will use is the MQ2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ2 smoke sensor reports smoke by the voltage level that it outputs. The ...
20190227· Gas detection. Gas detection for Raspberry Pi using ADS1x15 and MQ2 sensors. Description. The MQ2 sensor can detect multiple gases (CO, H2, CH4, LPG, propane, alcohol, smoke) and outputs analog voltage. This project can convert it to digital using ADS1015 or ADS1115 and filter out the target gases.
The eHealth Sensor Shield allows Arduino and Raspberry Pi users to perform biometric and medical applications where body monitoring is needed by using 9 different sensors: pulse, oxygen in blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG), glucometer, galvanic skin response (GSR sweating), blood pressure (sphygmomanometer) and patient position (accelerometer).
20191031· Answer. MQ9 has both a Digital and an Analog output signal, as summarized below: (a) Digital To detect gas leakage or no leakage, outputting High level , or Low, , respectively. (b) Analog To show gas intensity, outputting voltage in a range of to (a) Digital Rpi can use a GPIO pin to read the MQ9 digital output, after ...
Raspberry Pi ; Qwiic ; MicroMod ... the SGP30 gas sensor outputs measurements of total VOCs (TVOC) in parts per billion (ppb), carbon dioxide (CO 2) equivalent in parts per million (ppm) as well as raw gas readings of ethanol and hydrogen (H 2). The ethanol and H 2 readings are primarily intended for the SGP30''s onchip calibration and baseline compensation algorithms but they can be useful ...
Extended Code of the Raspberry Pi Robot. In order to follow the line, there are different modes that are checked: If both sensors detect the line, it is simply driven straight ahead, if only one of the two sensors detects the line, it is driven a little in the other direction. As soon as both sensors detect something again, the vehicle will drive straight ahead again. If neither of the two ...

Using a Raspberry Pi distance sensor (ultrasonic sensor HCSR04) For many (outdoor) projects a distance measurement is necessary or advantageous. These small modules are available starting at 12 bucks and can measure the distance up to 45 meters by ultrasound and are suprisingly accurate. This tutorial shows the connection and control.
20180323· Interfacing the PIR Motion Sensor to the Raspberry Pi''s Input GPIO. Read Now, we can try reading the output from the PIR motion sensor. The sensor outputs a digital HIGH (5V) signal when it detects a person. Copy and paste the following code into your Raspberry Pi …
Often you want to control modules with a higher voltage with the Raspberry Pi. For this purpose, relays can be used on the Raspberry Pi: The relay “switch” is utilized by means of a lowvoltage pulse. Since the Pi only tolerates a maximum of 5V (the GPIOs even only ) without relays, there is the risk that the Pi could burn out. However ...
MCP3008 PIN diagram V. RESULTS AND DISCUISSION The MQ2 gas sensor has been interfaced with the raspberry pi using the python coding language and output is measured using the thinner sample and shown in the shell widow. The values measured are in ppm (parts per million) range. Similarly other sensors can be interfaced with raspberry pi. Volume 9 Issue 2 December 2017 20 …
20190513· The DHT22 is a versatile and lowcost humidity sensor that can also calculate the temperature of an area. This sensor has a relatively long transmission distance, allowing the sensor to transmit data through wires up to 20m away from the Raspberry Pi. As a bonus, the DHT22 is a digital sensor with an inbuilt analog to digital converter.
