This sensor is built for detecting ppm of certain gas molecules, such as VOC, ethanol, ammonia, Hydrogen sulphide, etc. This sensor can't distinguish different gas molecules. Please use the table ...

This is where MQ-5 Combustible Gas Sensor comes into play. The MQ-5 Combustible Gas Sensor can detect LPG, H2, LPG, CH4, and CO. So in this article, we are going to discuss the MQ-5 sensor, and attach ...

The Arduino Sensor Kit base includes the following: Base shield with 16 Grove connectors, instead of just 12 Grove connectors on the Beginner Kit, including 7x digital connectors, 4x analog connectors ...

Sound Sensor with Arduino UNO – Connection Diagram Now that we have a complete understanding of how a Sound sensor works, we can connect all the required wires to Arduino as shown below. Connecting ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

This project involves building an Arduino-based auto-driving car that utilizes ultrasonic sensors to detect obstacles and make decisions on movement. The car can be started using a push button, and it ...

Not all cars came with fancy parking sensors or remote starting capabilities, and adding them as options can be expensive. But with a little DIY knowledge, and enough YouTube tutorials, you can make ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.
