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
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 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.
A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It is ideal for monitoring garden, or your plant’s water level. This is a must have tool for a connected garden.
This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).
It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. The IO Expansion Shield is the perfect shield to connect this senor to Arduino.
The new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation.
This 4 in 1 water quality sensor is a high quality industrial standard sensor that can measure EC (conductivity), TDS (total dissolved solids), Salinity and water temperature. This sensor enjoy high precision, long life and high stability in measurements. The sensor has RS 485 serial interface with 2-meter cable which can be extended to 1000 meter without affecting measured data quality, thanks to RS 485 long distance serial communication interface. It can be integrated with GPRS/4G/WIFI/LORA wireless module. Â
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
This is an industrial grade soil and water PH and temperature sensor. The new generation Ph sensor can measure pH and temperature level in both soil and water as well. Soil and water pH is a measure of the acidity or alkalinity of the soil or water. Soils (or water) can be classified according to their pH value where 6.5 to 7.5 is neutral soil (Ideal soil for growing plants), over 7.5is alkaline and less than 6.5 is acidic. The sensor has RS 485 serial interface with 2-meter cable which can be extended to 1000 meter without affecting measured data quality, thanks to RS 485 long distance serial communication interface. It can be integrated with GPRS/4G/WIFI/LORA wireless module.
The soil nutrient content can be easily measured using NPK Soil Sensor. Measurement of soil content N (nitrogen), P (phosphorus), and K (potassium) is necessary to determine how much additional nutrient content is to be added to soil to increase crop fertility.
The soil fertility is detected using NPK sensors. A major component of soil fertilizer is nitrogen, phosphorus, and potassium. The knowledge of the soil nutrient concentration can help us to learn about nutritional deficiency or abundance in soils used to endorse plant production.
This Soil NPK sensor is a low cost, quick responsive, high precision & portable Sensor that works with Modbus RS485. The advantage of this sensor over a traditional detection method is that it gives very fast measurement & data are highly accurate. All you need is to insert its probe in soil and get the reading using your MCU (Arduino, Tiva C, Raspberry, Personal computer).
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.

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.
