We are surrounded by invisible gases everywhere. While we generally don’t have to worry about them, under the right circumstances, they can be very combustible and dangerous. The MQ9 breakout board detects carbon monoxide, methane, propane, and other flammable gases so the right measures can be taken in time. The sensor detects carbon monoxide at 10-1000 ppm and other combustible gasses at 100-10000 ppm.

The digital and analog outs can be found on the through-holes. They are marked as DO and AO respectively. The digital output can be obtained by setting a threshold value with a potentiometer. The analog output will depend on the intensity of the gases.

Product usage tips:

The sensor needs 48 hours to preheat to optimal working temperature. If it detects some gas, the LED will glow. If there are no gases, it will remain off. The board can be attached to the project thanks to the two mounting holes. It comes with four pins that need to be soldered.

Due to its long life, the breakout board can be used for quite some time without a second thought. To prevent damage to the sensor, avoid dipping it in water or freezing it. Highly corrosive gases will weaken the sensor significantly.

Hydrogen is all around us, and it’s very flammable. Its leakage can be very dangerous to both life and property. That’s why it’s important to detect any leakage to prevent in the industry. To help with that, hydrogen sensors like the MQ8 breakout board are used. The sensor detects hydrogen at the range of 100-10000 ppm.

The digital and analog outs are on the breakout through-hole pins. They are marked as DO and AO respectively. By setting a threshold value with a potentiometer, you can get the digital output. The analog output will depend on how much gas is detected around the sensor.

A PIR (passive infrared) motion sensor is a device that detects physical movement within its field of vision by sensing changes in infrared radiation. This sensor works on the principle of detecting thermal thermal signals emitted by objects, mainly warm-blooded creatures like humans. The “passive” in the name refers to the fact that the sensor itself does not emit or radiate any energy for detection.

Easily connects to Dasduino/Arduino via digital pin. When it detects movement, it sets the output digital pin to HIGH. The angle that the sensor “sees” is 100 degrees and reaches up to 5 meters. It has a potentiometer for delay (how often to check for movement).

It is often used in a variety of applications, including home security systems, automatic lighting, and energy management, among others.

Light is one of the most important things in the life of most living beings. This is why it is common to work with light sensors when learning about electronics. A simple light sensor has a light dependent resistor (LDR) and sensor on a breakout board for easy wiring. The simple sensor comes with easyC connectors onboard, which enables quick and easy connection with Dasduino microcontroller boards.

As the name suggests, an LDR will change its resistance depending on the amount of light it is exposed to. The amount of light and resistance are inversely proportional. The more light it is exposed to, the less resistance it will have. So if there is more light, the board will have a resistance of several hundred Ohms. If the resistor is in the dark, it will have a resistance of several thousand Ohms.
