20200508· Air Quality Index Monitoring with ESP8266 MQ135. Now let us assemble the hardware and do the coding for the great IoT project. We will interface MQ135 Air Quality Sensor with NodeMCU ESP8266 Board and ″ I2C OLED Display. The circuit diagram is given below.

Because ESP8266 operates on and gas sensor operates on 5V we will add additional NPN transistor, two resistors and capacitor for voltage level sifter. Don''t forget to add capacitor it helps to set GPIO2 pin high during power on, to boot ESP8266 in …

I made a MQTT smoke detector with D1 mini and MQ2 sensor which powering by 4xAA NiMh battery. For a minute it goes deep sleep if everything clear, but if has a situation, deep sleep goes down 15 seconds. When it goes deep sleep the MQ2 switching down for energy saving. But even for that , the batteries goes down zero in 1416 hours.

20210829· Hey geeks, hope you are doing fine. This article will make our own smart smoke detector with an MQ2 gas sensor and NodeMCU. We can call it smart as it automatically detects the smoke and sends an alert notification to our smartphones. For controlling the MQ2 gas sensor we are using the Blynk app. You can read the full article on our website.

20160505· The MQ2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, …

20210614· Note: in this tutorial we’re connecting the DS18B20 data line to GPIO 4, but you can use any other suitable GPIO. Read our ESP8266 GPIO Reference Guide to learn more about the ESP8266 GPIOs. Note: if you’re using an ESP01, GPIO 2 is the most suitable pin to connect to the DS18B20 data pin. Preparing Your Arduino IDE. We’ll program the ESP8266 using Arduino IDE, so make sure you …
