When we make an application with Arduino, we have to use at least 1-2 sensors or modules. The strongest part of Arduino over other platforms is that it has many modules. The number of Arduino sensor modules is gradually increasing. Knowing what these sensor modules are means you know what materials to use in your projects.

This article will be an Arduino Sensor Wiki article. I will try to collect all arduino sensor types on this page as much as I can. So this article will be a long-term and comprehensive study.

6. Heartbeat detector module (finger)

Heartbeat detector module (finger)

This arduino sensor module has an interesting way of working. A red led flashes at a certain frequency. The photo transistor in the system detects this. When you put your finger in the module, the amount of light the photo transistor receives changes slightly depending on your blood pressure. So its resistance is changing. In this way, you can measure the heart rate.

7. Microphone sensor module

Microphone sensor module

Microphone sensor module detects ambient noise. Accordingly, digital outputs 0 and 1.
