Methane Gas Sensor MQ4 (Analog/Digital)
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.

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.
This smoke sensor module with MQ2 Smoke sensor have both digital and analog outputs , you also can adjust the sensitivity with the potentioneter.
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 analog gas sensor – MQ3 is suitable for detecting alcohol, this sensor can be used in a Breathalyser. It has a high sensitivity to alcohol and small sensitivity to Benzine. The sensitivity can be adjusted by the potentiometer.
The MQ-6 Gas sensor can detect or measure gases like LPG, methane and butane. The MQ-6 sensor module comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas. When it comes to measuring the gas in ppm the analog pin has to be used, the analog pin also TTL driven and works on 5V and hence can be used with most common microcontrollers.
So if you are looking for a sensor to detect or measure gasses like LPG, butane or methane with or without a microcontroller then this sensor might be the right choice for you.
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.

Conductivity (EC) is a measure of the ability of water to pass an electric current; it is affected by the presence of dissolved solids such as chloride, nitrate and phosphate. Conductivity can be a very useful indicator that a discharge of some sort has entered a stream, or some other change has occurred. TDS Sensor detects the Total Dissolved Solids (TDS) levels in the water which can be used to indicate the water quality. The Salinity Sensor easily and precisely measures the total dissolved salt content in an aqueous solution.Â
