MHZ14A is an Infrared Carbon Dioxide Sensor for accurate NDIR (nondispersive infrared) Co2 measurement using Arduino, STM32, Raspberry Pi. This NDIR Co2 sensor is a small size, common type sensor, NDIR principle to sense the presence of CO2 gas in the air. This NDIR Co2 sensor provides good selectivity, long life and nonoxygen dependent.

· Arduino UNO board; 2 x IR sensor fc51; 1 x 7segments display SMA42056; 8 x R = 220Ω. From schematic to code The schematic used in the object counter demo. To drive the 7 segment display we need for 7 digital output PINs as shown in We also need to read information from our two IR sensors. This requires to use 9 digital pins.

· In order to measure speed of a motor using Arduino, I have used an LM393 Speed sensor with Arduino. The LM393 Speed Sensor Module is basically an Infrared Light Sensor integrated with LM393 Voltage Comparator IC. The following image shows the speed sensor module I have used.

//Create names for digital pins define ir 7 define buzzer 8 define led 9 //Create variable to test against for sensor int obstacle; void setup() { //Set ir pin for INPUT so that it reads from the sensor pinMode(ir, INPUT); //Set led and buzzer to OUTPUT so that they can be turned on/ off pinMode(led, OUTPUT); pinMode(buzzer, OUTPUT); } void loop() { //read from the IR sensor and assign ...

· Test IR sensor FC51 with serial terminal (Demo 01) Demo 1 schematic. In the first demo, through the connection between the Arduino serial port and the PC, we will read about the detection of the object. Lets take a look to steps required by this …

· Arduino Uno Serial Monitor (for MH sensor series) anyang May 21, 2021, 5:00am 1. Hi, I am having an issue with Serial Monitor not showing the correct readings in serial monitor. I have 2 MH sensor which is detecting the rpm/revolutions for my DC motor using encoder disks. When i tested the sensors individually, it shows correct analog and ...

· 1. Introduction: This is a multipurpose infrared sensor which can be used for color sensor provides a digital as well as analog output. An on board LED is used to indicate the presence of an object. This digital output can be directly connected to an Arduino, Raspberry Pi or any other microcontroller to read the sensor output.

· What is an infrared sensor? An infrared sensor is an electronic device, that emits in order to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detects the types of sensors …

· Test IR sensor FC51 with serial terminal (Demo 01) Demo 1 schematic. In the first demo, through the connection between the Arduino serial port and the PC, we will read about the detection of the object.

How to Use TCRT5000 IR Sensor Module With Arduino UNO: In this tutorial, we are going to teach you some basics on using TCRT5000 IR Sensor Module. These basic are showing you the analog and digital values at serial :This IR reflective sensor utilizes a TCRT5000 to …

· IR Flying Fish sensor going haywire. I have an IR (Infrared) sensor. It seems to always detect an object, at ALL times, no matter how far an object is. I’m pretty sure it can’t detect anything further than a few inches, and yet even when the nearest object is nearly a meter away, it’s LED lights up to show that it has detected an object.
