· MQ2 Gas sensor doesn’t want to work with esp32cam. has anybody here used mq2 sensor with esp32cam.. i was trying to make it work in the past couple days but no result.. i tried with different pins (1,3,0,16,2) but nothing.. all i get is 0. my code is like this: int pin = 2 ; pinMode(pin,INPUT); (analogRead(pin)); ps: same code + same sensor work fine On Arduino uno. Touch ...
· This Sensor is most commonly used for the Smoke and Gas detection. This Gas Sensor mq2 Module features an MQ2 sensor. The MQ2 sensor is a versatile gas sensor capable of detecting a wide range of gases including alcohol, carbon monoxide, hydrogen, isobutene, liquefied petroleum gas, methane, propane, and smoke.
· MQ2 smoke sensor or gas sensor is suitable for detection of Hydrogen, methane and LPG related gases. In short, it can detect combustible gases. It has a wide operating detection range. It has very high sensitivity and very fast response rate. It can even be used in harsh environments. So you can easily use it detect the presence of gas or smoke in your surrounding. There are many smoke ...
· The MQ2 is a sensor that allows gas or smoke detector at concentrations of 300 ppm to 10,000 ppm. After calibration, the MQ2 can detect various gases such as LPG, ibutane, propane, methane, alcohol, hydrogen and fumes. It is designed for indoor use at room temperature. Supplied in 5V, it has an analog output and a potentiometer sensitivity adjustment. You can also find it with a Grove ...
· Example: Gas Sensor with Arduino. In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. Parts needed: So, for this example, you’ll need: 1 x MQ2 gas sensor
· Generally, for gas leakage detection (home and industry), we will use the MQ2 module. It is suitable for detectingH2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to the high sensitivity and fast response time of it. But, in this design, we used the MQ2 sensor for the smoke situation. This sensor has four outputs, namely, Vcc, ground, D0, and A0.
· Connectez les 3 broches du capteur à l’Arduino (ou ESP32 / ESP8266) en suivant le schéma de câblage suivant . Reliez les Pins Vcc et GND du capteur au 5V et au GND de l’Arduino. Reliez le Pin D0 du capteur à l’entrée analogique A0 de l’Arduino. Code de base. Voici le code vous permettant de tester votre MQ2. Par défaut, la sortie analogique du MQ2 est branchée sur l’entrée ...
· Gas Level Monitoring Over Internet Using ESP8266 Gas Sensor. In this project, we will learn about Gas Level Monitor On Internet Using ESP8266 Gas Sensor Module, will measure the quantity of gas in percentage and …

The Gas Sensor (MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer. The sensor is actually enclosed in two layers of fine stainless steel mesh ...
To do so, we will first employ a gas sensor module, MQ2, and the temperature and humidity sensor DHT22 (AM2302). Both will be read by the first ESP32 LORA, which will function as the Sender, and will send an alert to the second ESP32 Lora, which will be a Receiver. This provides safety for a situation such as a gas leak, for example.
· In this tutorial I show you how to use the MQ2 gas sensor with your Arduino, ESP8266 or ESP32 microcontroller. After we dive into the functionality of gas sensors in general, we build a gas alarm with the MQ2 gas sensor …
