This smoke sensor module with MQ2 Smoke sensor have both digital and analog outputs , you also can adjust the sensitivity with the potentioneter.
EGP95.00
PIN Connection
4 pins as follows:
- VCC Â Â (5 V)
- GND (ground)
- Aout (Analog output)
- Dout (Digital output)
When connect to arduino, use digital pins in digital mode (high or low) and use analog pins for analog mode (diffrenet value for different smoke intensity).

The MQ7 is a simple-to-use Carbon Monoxide (CO) sensor suitable for sensing CO concentrations in the air. It can detect CO-gas concentrations anywhere from 20 to 2000ppm. MQ7 is a high sensitivity to carbon monoxide and stable and long-life span.
The MQ-135 gas sensor senses gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide, and smoke.
The boost converter of the chip MQ-3 gas sensor is PT1301. The operating voltage of this gas sensor is from 2.5V to 5.0V. The MQ-3 gas sensor has a lower conductivity to clean the air as a gas sensing material. In the atmosphere, we can find polluting gases, but the conductivity of the gas sensor increases as the concentration of polluting gas increases. MQ-135 gas sensor can be implemented to detect the smoke, benzene, steam, and other harmful gases. It has the potential to detect different harmful gases. The MQ-135 gas sensor is a low co st to purchase.
This environmental sensor module is based on BME680 powerful environmental sensor. It can sense temperature, barometric pressure, humidity and VOC (volatile organic compound) gas of the surrounding environment.
You can monitor 4 environmental parameters simultaneously. All the measurements can be read through either I2C or SPI connection. With the BME680 you can monitor the air quality, surrounding air status, industrial pollution and controlled farming environment. Applications is not limited to weather forecasting, HVAC, home automation, fire protection systems, hazards storage area monitoring and medical space environment watching.
TDS (Total Dissolved Solids) measures how many milligrams of soluble solids dissolved in one liter of water. The measure is expressed in PPM (part per million). In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water.
Thanks to this product, it becomes possible to create your own measurement, collection and data transmission system. It is even possible to use this information to automate water treatment cycles. The TDS probe is waterproof; it can be immersed in water for long time measurement. However, the signal transmitter board is not waterproof.
The VOC (volatile organic concentration) gas sensor is mainly used to detect and measure the concentration of VOC gases such as: Formaldehyde, Acetone. Acetic Acid, Benzene, Toluene, xylene, Butanal, Carbon Disulfide, Methylene Chloride.
The sensor module is based on MS1100 sensor which is semiconductor type sensor product widely used in ventilation equipment, ventilation fans, air filters, hoods, home appliances and other equipment. With high sensitivity and stability, it can detect more than 0.1ppm concentration of VOC gases in air.
The measurement of dissolved carbon dioxide in water is one of the most important parameters in the field of aquaculture and in industry. So, this Carbon Dioxide (CO2) sensor probe allows the measurement of dissolved carbon dioxide directly in the water and soil. It can measure the Carbon Dioxide (CO2) concentration with high accuracy with large measuring range up to 5000 ppm. The CO2 probe has an analog both RS485 and TTL output for connection to your acquisition system.
You simply need to immerse the CO2 probe directly into the environment you want to monitor, whether it’s a fish farm pond, a lake, the open sea, in a bioreactor, or a manufacturing process. The sensor then provides a continuous measurement of the partial pressure of dissolved CO2 in water.
This sensor has a high sensitivity and fast response time. It is suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm.
The sensor can output an analog or digital signal. The sensitivity can be adjusted by the potentiometer.
They are used in gas leakage detecting equipments in home and industry applications.
MQ-4 Sensor is highly sensitive to Methane – CH4.
Using a MQ sensor and detecting the gas is quite easy. You can either use the digital pin or the analog pin to accomplish this. Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas is detected the output LED will remain turned off meaning the digital output pin will be 0V.

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse Signal. Can be used with ardduino
The Chirp! Plant Watering Alarm is a new device from wemakethings that helps extend the life of your plant by reminding you to water it. This plant water alarm is essentialy a moisture sensor with built-in coin battery and sound alarm. Chirp is a plant watering alarm – as simple as that. You put it into the soil near a plant and it emits a tiny chirp (sharp sound) when the soil is dry, reminding you to water the plant. Alternatively, Chirp can work as an I2C soil moisture sensor.
Non-contact liquid level sensor can be used to provide external monitoring in liquid non-metallic material tubes, pipes and tanks such as plastic, glass, fiber-glass and ceramics. The thickness of the tube/pipe/tank/container should be less than 10mm. It is easy to use as a led is on when the liquid level reached and voltage is detected from sensor output.
The contactless liquid level sensor can be used in household appliances products, drinking and cleaning water and water treatment equipment, medical treatment and foodstuff mechanism equipment, chemical mechanism equipment and so on.
