MG812 CO2 érzékelő rendkívül kis teljesítményű szén-dioxid érzékelő modul, levegőminőség érzékelő modul, 0-10000 ppm MG-812 érzékelő modul
MG812 CO2 Sensor Ultra Low Power Carbon Dioxide Sensor Module Detection Air Quality 0-10000ppm MG-812 Sensor Module
Instructions for use:
Power supply voltage: 5V
AOUT: analog output, the change of the voltage value corresponding to the gas detected by the chip, the microcontroller can directly use the ADC to connect.
DOUT: digital output value, which is the result of comparing AOUT and the output voltage value of the adjustable resistor. Output semaphores 0 and 1.
Adjust the adjustable resistance of the module. When the output voltage of the adjustable resistance is less than AOUT, DOUT outputs a high level and the LED light is on; otherwise, DOUT outputs a low level and the LED light is off
Size: 15mm X25mm
Weight: 2.56g
Notes on using the module:
When it needs to be used, it is necessary to warm up the module for 3-5 minutes, and then perform related measurements.
Connect with the microcontroller:
VCC——5V MCU GND——MCU GND
AOUT - AD input pin of the microcontroller
DOUT - any available pin of the microcontroller
