These 5 sensors are most commonly used by Electronics makers and engineers to build DIY projects. All these sensors are compatible with Arduino, and are easy to use.
The MQ-135 Gas sensor can detect gases like Ammonia (NH3), sulfur (S), Benzene (C6H6), CO2, and other harmful gases and smoke. Similar to other MQ series gas sensor, this sensor also has a digital and analog output pin.
DHT11 Digital Temperature And Humidity Sensor is a basic and low-cost digital temperature and humidity sensor.
The soil moisture sensor can be used to measure the moisture content in the soil by measuring the ambient humidity.
HC-SR501 sensor is a Passive InfraRed (PIR) sensor that is used for motion detection. It is commonly used to detect the motion of human body in security or proximity applications.
The TCS3200 color sensor senses the color of an object and produces an equivalent frequency signal (square wave) based on the color sensed.
