mq2 gassensor
Sep 15, 2020· The MQ2 gas sensor has an operating voltage between and 5V that is also used as heater for the surface of the SnO2. Therefore the microcontroller we use has to provide a stable 5V output. Arduino microcontroller have already an operation voltage of 5V but we have to power the ESP8266 and ESP32 boards via USB to get an 5V output. Get Price. Chat With WhatsApp. MQ2 Gas …
Detector using MQ2 Gas Sensor and Arduino
20171221· In this Smoke Detector Circuit with Arduino, we have used a MQ2 Gas Sensor to detect preset smoke in the air. A 16x2 LCD is used for displaying the PPM value of Smoke. And an LM358 IC for converting smoke sensor output into digital form (this function is optional). A buzzer is placed as an alarm which gets triggered when smoke level goes beyond 1000 PPM.
