May 05, 2016· 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, the lower the output voltage. When the Arduino …
Apr 26, 2015· Hi sir, when i use mq 135 sensor my sensors value drops to 0(zero) after some time . i am using my sensor in a small air conditioned lab (9*3*3)meters with 3 or 4 persons ,so what could be expected CO2 concentration in ppm.(note: sensor is not detecting below 10 ppm, when value is less than 10 ppm it gives zero value)
Jun 20, 2017· This is a NDIR, digital, autocalibrating sensor, so it''s pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino. This photo shows K30 connected to Arduino. CO2 measurements are displayed on LCD1602 screen.
May 24, 2019· Switch options: Connect any crank timer to the OL/OC spots on the ERV control bus. Crank timer could be a smart switch (on/off) that has IFTTT enabled. Airthings Wave+ works with IFTTT, so a trigger for CO2 can be set to toggle b/t ON/OFF to bump the ERV into high speed when CO2 is over 1,000ppm, and off when under 1,000ppm.
