hepl for high school CO2 sensor project - Arduino Forum

2021-05-05· Hello from Turkey. I'm a geography teacher. We want to make a high school project with my student. But inexperienced about arduino. And That's why we need your helps. We'll use the arduino uno MG-811 CO2 sensor and MQ-135 air quality sensor and Nokia 5110 led screen. Question 1: We can make connections on breadboard for MG 811. But i write whatever code it's always a constant …

Measure CO2 Levels With Ardunio and K-30 Sensor : 9 Steps ...

While the Arduino's 5V power is theoretically able to power the K-30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC's USB port, the K-30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under 300mA, and it won't operate properly.

CO2 Sensor Sketch resets randomly - Sensors - Arduino Forum

2021-05-06· I have the following sketch for getting data from a co2 sensor. I attached the schematic. The issue I’m having: The sketch seems to reset randomly. I can tell because it runs through void setup multiple times. #include <> SoftwareSerial mySerial(12, 13); // RX, TX pins on Ardunio int co2 =0; double multiplier = 1;// 1 for 2% =20000 PPM, 10 for 20% = 200,000 PPM uint8_t buffer ...

Arduino Compatible CO2 Sensor - SG112A - Aretas Sensor ...

2019-11-08· Since the SG112A UART is only 9600 bps, you can use a SoftwareSerial port on the Arduino to communicate with the CO2 sensor and use Hardware Serial for viewing the output. The sensor (by default) emits a CO2 reading via UART every 2 seconds. The SG112A is compatible with the SG111A firmware. To see the output from the sensor, download the SG111A-Test-Sketch from our GitHub repo for the sensor ...
