MQ 7 Carbon Monoxide Sensor Circuit Built with an Arduino

MQ-7 Carbon Monoxide Sensor Circuit Built with an Arduino

In this project, we will go over how to build a carbon monoxide sensor circuit with an Arduino. The carbon monoxide sensor we will use is the MQ-7 sensor. This is a sensor that is sensitive to effects of CO. Carbon monoxide (CO) is a very dangerous gas which is odorless, colorless, and tasteless, so

How to Build a Soil Moisture Sensor Circuit with an Arduino

In this project, we are going to build a soil moisture sensor with an Arduino microcontroller. A soil moisture sensor, also called a hygrometer, measures the amount of moisture, or water, in the soil. Therefore, we can tell whether the soil has enough moisture or not. So it is a good diagnostic tool for caring
