The Grove 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. Note

Sep 15, 2020· MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32. 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 that detects smoke and turn on an active buzzer as alarm.

Feb 27, 2018· MQ135 Sensor Features. Wide detecting scope. Fast response and High sensitivity. Stable and long life. Operating Voltage is +5V. Detect/Measure NH3, NOx, alcohol, Benzene, smoke, CO2, etc. Analog output voltage: 0V to 5V. Digital output voltage: 0V or 5V (TTL Logic) Preheat duration 20 seconds.

The Tasmota firmware is very easy to install on Sonoff home automation modules. It installs instead of the official firmware and drive these modules from almost all home automation servers Open Source (Domoticz, Home Assistant …). You can also control all your Tasmota accessories without going through a home automation server directly from Homy.

Configuration options: topic (Required, string): The MQTT topic to publish the message.. payload (Required, string): The message be filled by the actual payload with some options, like log_topic. qos (Optional, int): The Quality of Service level of the topic. Defaults to 0. retain (Optional, boolean): If the published message should have a retain flag on or not.

IR Communication. The default Tasmota firmware variants include support for IR send/receive for a limited set of protocols (see IR Remote ). Tasmota uses the IRremoteESP8266 library that supports numerous protocols. Each protocol consumes some memory, especially air conditioner protocols (up to 81k of flash size).

Aug 18, 2019· MQ2 sensor (I had lying around) IR transmitter (as my ceiling light apparently is supposed to have a remote control) Using a previously flashed Tasmota nodemcu I decided to wipe it clean using a 1MB blank file and flashing it at 0x00000, 0x10000, 0x20000, 0x30000 using the ESP8266Flasher

For this I was looking at using a NodeMCU, a MQ4, a MQ7 and a MQ135 along with some other things and having it report back to HA via MQTT. Reason being for multiple sensors is one will pop on CO2 or CH4, one is mainly for CH4 and the other is smoke. Granted these don’t replace the standard commercial smoke and gas sensors in the house but ...

Mar 20, 2019· (Setting up Tasmota with Embedded MQTT broker) OH has full autodiscovery for Tasmotas though (And hopefully also a Paper UI replacement that is easier to grasp.) Hi Dave I up graded to OH last week and it didn’t find any of my Tasmota controlled boards when I did a search. Is there anything special I needed to do? John

Dec 05, 2017· My apologies I should have been more clear. Which gives the Pi Analog input. For the voltage issue the plan was to use a step up converter from 3v3 to 5v for the sensor. Plan A was to connect the sensor directly to the Sonoff Basic, which would be ideal as its close to the gas source to be monitored.

Nov 22, 2020· In the 1990s, the wellknown designer Luigi Colani asked why computers always have to be square and angular. He was right, they don''t have to be. Not even our small micro controllers. The proof is provided by the new circular AZEnvy, a micro controller board with the ESP826612F and two builtin sensors for environmen
