20191203· Following the ESPHome introduction, we use the Winsen CO2 sensor to measure indoor CO2 level. For reference look at the datasheet. The sensor outputs the measured CO2 level in a PWM signal and a UART (serial) stream. We will use the UART interface in our example. Connection. We need four connections: power (5V – 150mA, GND, Rx and Tx). If you ...

But here''s the problem: Arduino can''t provide enough power to run this sensor from its pins sensor''s heater requires 150 mA, while Arduino pin can provide no more than 40 mA, so if attached directly, Arduino pin will burn and sensor still won''t work. So we must use some kind of current amplifier that takes small input current to control large output current.

MHZ14 NDIR Infrared gas module is a common type, small size sensor, using nondispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, nonoxygen dependent and long life. Builtin temperature sensor can do temperature compensation; and it has digital output and analog voltage output. This commons type infrared gas sensor is developed by the tight ...

The Grove SCD30 is a 3in1 Arduino sensor that can measure CO2, temperature, and humidity. Based on Sensirion SCD30, it is a NonDispersive Infrared(NDIR) carbon dioxide sensor with high precision and wide measurement accuracy which can reach ±(30 ppm + 3%) between 400ppm to 10''000ppm. It would be a perfect choice if you are not looking for a simple Arduino temperature …
