Butane, LPG & Smoke sensor MQ2 breakout
Butane, LPG & Smoke sensor MQ2 breakout

MQ sensors, including the MQ2 sensor, have the capability to detect various gases. The MQ2 sensor is specifically designed to detect combustible gases such as LPG (liquefied petroleum gas), butane, propane, methane, alcohol, hydrogen, and smoke. These gases are commonly found in residential, industrial, and automotive environments. The sensor’s sensitivity and responsiveness enable it to detect even trace amounts of these gases, making it a valuable tool for gas leakage detection, fire detection, and air quality monitoring applications. It takes a short time to heat up in order to work correctly.

 

The breakout board works with both digital (DO) and analog signals (AO). The digital output is obtained by setting a threshold value with a potentiometer. The analog output will differ depending on the intensity of the gas.

 

Product usage tips:

 

When gas is detected, the LED will start glowing. It will remain off if it doesn’t detect anything. Two mounting holes enable easy mounting to surfaces. The board comes with four pins that need to be soldered.

 

Load cell module high precision 10kg
Load cell module high precision 10kg

Load cell is a small device that is able to weigh the load on it. Due to the load, it provides very small output voltages that need to be amplified (eg using op-amp or ADC with a built-in op-amp) to find the use for the module. It incorporates two invariable two variable resistors connected to the Wheatstone Bridge. This sensor is made from high-quality materials, so it does not get affected by high temperature or continous load. You need to connect it with the HX711 to read information with Croduino.

Voltage & current sensor INA219 breakout
Voltage & current sensor INA219 breakout

The INA219 is a digital device that allows the measurement of current, voltage, and therefore power. Simply, connect wire serial through this device and it will give all the information provided via I2C communication. It is very simple and reliable to use. It has a jumper for making changes to the I2C address so you can connect more than one INA219 to single microcontroller.

The maximum current of the measurement is determined by the shunt resistor found on the plate which is 0.1ohm (± 3.2A). Yes, it can measure the power in both directions! If you want to measure other currents or smaller currents more precisely, check out the datasheet to change that resistor. The maximum voltage that can be measured is 26V.

Alcohol, Ethanol sensor MQ3 breakout
Alcohol, Ethanol sensor MQ3 breakout

MQ sensors, including the MQ3 sensor, have the ability to detect various gases. The MQ3 sensor is specifically designed to detect alcohol vapors. This means it is sensitive to alcohols such as methanol, ethanol, and isopropanol. The MQ3 sensor is commonly used to measure the concentration of alcohol in the air and is a useful tool for alerting to the presence of alcohol in the surrounding environment.

It is important to note that MQ sensors are not specific to only one gas and can react to other gases besides those they are specifically designed for. Therefore, it is important to use the MQ3 sensor exclusively for alcohol detection and to follow the manufacturer’s instructions to achieve optimal accuracy and reliability of measurements. It requires a short heating time to function correctly.

The breakout board works with both digital (DO) and analog signals (AO). The digital output is obtained by setting a threshold value with a potentiometer. The analog output will differ depending on the intensity of the gas in the sensor’s environment.

 

Product usage tips:

 

When gas is detected, the LED will start glowing. It will remain off if it doesn’t detect anything. Two mounting holes enable easy mounting to surfaces. The board comes with four male headers that need to be soldered.

Air quality sensor CCS811 breakout
Air quality sensor CCS811 breakout

The CCS811 sensor is designed to measure various volatile particles in the air (TVOC – Total Volatile Organic Compounds), which include eCO2 (CO2 equivalent) and MOX (metal oxides). VOCs are generally defined as air pollutants, and can come from a variety of sources, starting with ordinary breathing, smoking, coloring, welding, and generally all processes that release particles into the surrounding air.

 

This sensor is often used to measure indoor air quality, which can work very well and indicate current air pollution, for example, in an office.

Shunt resistor 10A
Shunt resistor 10A

The Shunt Resistor is a special type of resistor with small resistance which allows large currents to pass through it. This is useful for measuring the current in a circuit: due to the Ohm’s law and voltage drop on the shunt resistor, we can know exactly which current passes through it. For example, for this resistor whose maximum current is 10A, the voltage drop at that current will be exactly 75mV (0.075V). Using a precise ADC, we can accurately measure the current of our consumer or power source.

 

Max. current: 10A
Voltage drop for max. current: 75mV

Simple rain sensor
Simple rain sensor

Water is essential for life on Earth. Using water efficiently is very important. With the easy-to-use simple rain sensor, farmers can save water while irrigating their crops. The sensor will alert them to shut down the water supply when it senses rain. It can even act as an automatic on and off switch, like turning on wipers on a car when it senses rain.

 

This sensor has two pieces – the rain sensor and the simple sensor. The rain sensor has nickel-coated lines on both sides. It measures moisture and outputs the data to the simple sensor that reads it. The simple sensor uses the LM393 differential comparator. The main benefit of this board is ability to give analog and digital output. By setting the potentiometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.

Simple light sensor board
Simple light sensor board

Light is one of the most important things in the life of most living beings. Because of this, it is common to work with light sensors when learning about electronics. The simple light sensor features a light-dependent resistor (LDR) and a sensor on a small breakout board for easier connection. As the name suggests, the LDR will change its resistance depending on the amount of light it’s exposed to. The amount of light and resistance are inversely proportional. The more light it’s exposed to, the less resistance it will have. Thus, if there’s more light, the board will have a resistance of a few hundred Ohms. If the resistor is in the dark, it will have a resistance of several thousand Ohms.

 

The main benefit of this board is ability to give analog and digital output. By setting the potenciometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.

Stainless steel water level sensor
Stainless steel water level sensor
The float sensor allows you to detect the height of water or some other liquid in the tank. This float sensor works on the principle of magnets and magnetic (reed) switches. Usually, it is mounted on the bottom or top of the tank, and when in water, the floating part with a magnet, triggers the magnetic switch. This alteration can be detected and trigger a certain action; eg filling the tank or launch alert. Sensor itself is made out of stainless steel and it won’t rust in humid enviroments.

The water flow meter allows you to find out the amount of water that has passed through the sensor in units of liters per minute. It consists of a plastic valve, a water-rotating rotor and a hall effect sensor. When water passes through the rotor, it rotates at different speeds, which the hall effect sensor measures. This signal is read and converted to L / min.
