![]() View this module on eBay -> 7. Digital Thermal Sensor Module Temperature Sensor Module For example, you can build a Night Security Light project. You can use this module for light detection with an Arduino. View this module on eBay -> 6. Photoresistor Sensor Module Light Detection Light Here’s the complete guide on how to use this sensor. This sensor also measures temperature and humidity. By converting the pressure measures into altitude, you have a reliable sensor for determining the height of your robot or projectile, for example. You can use this module to measure the absolute pressure of the environment. View this module on eBay -> 5. Digital Barometric Pressure Sensor Board Learn how to use this sensor with our complete guide. The threshold-sensitivity can be adjusted via potentiometer on the sensor. The digital output sends a high signal when the sound the sound intensity reaches a certain threshold. This module has two outputs: AO (analog output), or DO (digital output). Here’s the complete guide on how to use the hygrometer module with your Arduino. Use this sensor to create an automatic self-watering plant. You can also read an analog signal whose value is proportional to the moisture level. It outputs a high signal when the moisture is above a certain threshold. This is a simple water sensor that can be used to detect soil moisture. View this module on eBay -> 3. Soil Hygrometer Detection Module Soil Moisture Sensor The module detects the distance 2 ~ 30cm, detection angle 35 °. When the module detects an obstacle, the green indicator light on the board lights up. These sensors have a digital output pin that outputs a signal when it detects an object. This module is very easy to use and is often used in robots to detect objects near the sensor. ![]() IR Infrared Obstacle Avoidance Sensor Module Here’s a complete guide on how to use this module. ![]() It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats do. We also have instructions on how to use most of them with the Arduino. In this guide we’re going to show you a collection of 21 Arduino sensors and modules you can buy for less than $2. There are sensors for almost anything you can think of. Sensors are awesome because they allow us to know what’s going on in the outside world. Let’s start! List of the Best 21 Arduino Modules The Arduino community has created a wide variety of modules and shields that can enhance your projects. Here’s the ultimate collection of 21 Arduino Modules that you can get for less than $2 on eBay.
