Hi All, today, im showing you how to setup and Code a MQ135 CO2 Sensor this will give an estimated measure of the PPM (parts per million) in the am usi...
DHT11 Temperature and Humidity sensor printing to an I2C 16x02 LCD. This project measures ambient temperature and humidity and displays the date on the LCD. This is a standard project.
140+ ESP32 Projects, Tutorials and Guides with Arduino IDE. The ESP32 is the ESP8266 successor loaded with lots of new features. The ESP32 is a development board that combines WiFi and Bluetooth wireless capabilities, and it’s dual core. It supports a wide variety of peripherals such as: capacitive touch, ADC, DAC, I2C, SPI, UART, I2S, PWM ...
· No worries, as Seeed got the solution for you with our Seeeduino Nano: Seeeduino Nano () The Seeeduino Nano is a compact board which is fully compatible with the Arduino Nano on pinout on sizes. The first you will realise about the Seeduino Nano is the price of it. It only costs which is 6 times cheaper than the Arduino Nano!
· The MQ135 sensor is a signal output indicator instruction. It has two outputs: analog output and TTL output. The TTL output is low signal light that can be accessed through the IO ports on the Microcontroller. The analog output is an concentration, increasing voltage is directly proportional to increasing concentration. This sensor has a long life and reliable stability as well.
Der MQ135 Sensor ist ein Modul, welches die Konzentration verschiedener Schadstoffe in der Luft erfasst. Der Sensor gibt die erfassten Schadstoffwerte als analogen Wert aus. Diese können im Anschluss im seriellen Monitor ausgegeben oder anderweitig verarbeitet werden.

· MQ135 is a gas sensor which is sensitive to CO2. The change in CO2 levels changes the resistance of sensor which results in the change in the output of the sensor. The output generated from the sensor is feed to Analog Input to Arduino board ( In my case Arduino Uno). The analog data is taken by ADC of Arduino, according to the voltage levels ...

Dans mon projet, j’envisage de rajouter un MQ135 quand je serai plus familier avec le DSM501 et la programmation… Projets DIY 15 novembre 2017 à 18 h 17 min Oui mais j’ai l’intention d’en faire un hack pour ajouter des capteurs supplémentaires. j’ai déjà le capteur CO2.
· Download the MQ135 Library and include it in your Arduino IDE. Prepare the hardware setup with MQ135 gas sensor and 10KΩ Load Resistor (RL) After the 24 hours preheat process, perform the following procedures in the environment of 20 degree C/35% air temperature, and read the value of RZERO. include "".
The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases: The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a builtin potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.
What is MQ135 gas sensor and how does it work? The gas sensor module consists of a steel exoskeleton under which a sensing element is housed. This sensing element is subjected to current through connecting leads.
· The MQ811 is much more expensive (30 compared to 3). The datasheet claims that the MQ135 is sensitive for CO2, Alkohol, Benzene, NOx, NH3 and the Fig 3 shows the change in resistance depending on the concentration of these gases in the ambient air in ppm (of the total gas volume).
· But, in this project, we will only play a buzzer. We will also include one red and one green LED. Circuit Diagram for MQ135 gas sensor. We are going to receive analog value from the sensor. We used the Arduino A5 pin. So we connected the A5 pin with the 4th pin in the sensor. The sensor GND and VCC goes to Arduino GND and 5volt.
