CO2 Sensor Sketch resets randomly - Sensors - Arduino Forum

2018-05-11· 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 …

CO2 Test lung regulator - Project Guidance - Arduino Forum

2016-01-19· 2021-05-05· Hello, I am new to arduino and I wondered if anyone would like to help me. For a project I am making a test lung where I have to regulate the amount of CO2 that is going in. I do this using a arduino. I am using: -Arduino Uno -Continious rotation servo (to open the valve of the CO2 bottle) -CO2 sensor (MQ 135) -Pontentiometer (to control the servo) Right now i have the code: -To …

MPU9150 keeps going to sleep - Sensors - Arduino Forum

2021-05-06· Hi all This is my first post here and I'm relatively new to electronics but I'm having immense fun with my little project. I have an Arduino Due and I'm using an MPU9150 (GY-80) 10DOF sensor. I have everything connected up correctly (I believe) and most of the time, I can read all 3 of the sensors' data (I have another question coming on the Magnetometer but that'll keep for another day).

(I don’t have the sensor, mainly helped to stabilize and optimize the lib) cope February 8, 2016, 10:13am #162. I have a Cozir ambient sensor and the CO2, temperature and relative humidity output is working fine thanks to all the input I got from this thread. The problem is that the CO2 …

CO2 gas sensor and solenoid valve - Sensors - Arduino Forum

2018-03-08· 2021-05-06· So far I have gotten the arduino and vernier sensor interface shield to read the CO2 levels, but when adding a motor shield into the mix, the CO2 can no longer be read. The gas valve I am using is a US solid model #JFSV00065. The motor shield will not turn the valve on or off with the code I am using. Not sure if its the code or the valve. Heres what I have so far:

Turning the PIR Sensor On/Off - Arduino Forum

2018-04-23· 2021-05-05· Turning the PIR Sensor On/Off. The purpose of this code is to turn on and off a PIR Sensor, which activates the piezo buzzer if the sensor detects movement. The activation of the buzzer portion of the code works, but I am stuck on the on and off switch part. I attempted to use an if-else statements, but the code didn’t work.

TGS4161 CO2 Research - Arduino Project Hub

K30 CO2 Sensor - to verify the readings; " TFT display - to make some readings without going online; So far I've identified few things that i would like to share with other having the same goal. Accuracy: If used correctly - the sensor is VERY accuarte. I am comparing it to my K30 CO2 (which is rated ~3% accuracy) and I can tell that response times and readings are within 5% difference. Yet ...

K33 CO2 sensor + Motor driver - Sensors - Arduino Forum

2021-05-06· Hi, I am working on a project designed to measure oceanic CO2 levels, and for this I need to be able to run an air pump and a K33 sensor off of an arduino. The set up I have turns on the air pump for 15 seconds (via a Drok 7A output motor driver), turns it off, takes a CO2 reading, waits a bit, and then turns the air pump back on. However, I have run into a problem. I have made a functional ...

arduino - PIR sensor always gives HIGH - Electrical ...

2016-03-04· 2016-03-04· If you have a 10 k resistor to hand then connect that between OUT and the 5 V supply. If this works then you need to enable the internal pull-up resitor on the Arduino. See the documentation for that. If that still doesn't work then measure the voltage between the PIR sensor pin 2 and GND while someone fires an infra-red remote control beam at ...

Arduino + CO2 sensor MG811 - Interfacing - Arduino Forum

2021-05-06· Yes, you do need 6V to run the heater in the Co2 sensor, the arduino will not supply this so you must get the sensor it's own voltage regulator. I have the circuit set up and it works perfect. I just need to code and calibrate. Here soon in the next few days I'm going to set up a page on I'll come back and post a link when it's finished.
