Gravity: Analog CO2 Gas Sensor For Arduino (MG-811 Sensor) _ARD_SHIELD_RELAY green and blue ultra-bright LED

green and blue ultra-bright LED

Visible display dimensions: 50

May ship with either WS2812B or SK6812-based LEDs

40mA during listening

The PWM is built into each chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you

Gravity: Analog CO2 Gas Sensor For Arduino (MG-811 Sensor) _ARD_SHIELD_RELAY green and blue ultra-bright LEDGreenhouse Effect is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2(Carbon Dioxide), we can do something to reduce the CO2 and to protect our Earth. Here is the Arduino based CO2 sensor designed by DFRobot lovely engineer. This is the first CO2 sensor in the Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is
