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
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.
Water detection sensor is used to detect water leak, water level or rains. This is obtained by having a series of parallel wires exposed traces. The sensor traces have a weak pull-up resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace.
The analog signal output can be read directly to arduino
This smoke sensor module with MQ2 Smoke sensor have both digital and analog outputs , you also can adjust the sensitivity with the potentioneter.
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.
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.
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.
Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensors conductivity is more higher along with the gas concentration rising. The sensor convert change of conductivity to correspond output signal of gas concentration.
MQ-5 gas sensor has high sensitity to Methane, Propane and Butane, ch4 and natural gas.
This is an high flow oxygen sensor to measure oxygen concentration (percentage) and gas Volumetric Flow Rate. The sensor measures the gas temperature also. The Oxygen sensor in home and medical oxygen generator, PSA oxygen generator, anesthesia monitors, medical ventilator, breathing equipment, oxygen analyzer, hospitals, laboratories, combustion and environmental applications.
The Oxygen sensor output oxygen concentration, flow rate and temperature digital data through serial UART. This make it it easy to receive data and handle it using Arduino, microcontroller or pc interface.
The oxygen sensor uses the ultrasonic velocity difference between upstream and downstream to measure oxygen concentration. This cutting edge ultrasonic technology enables small size, stable, high accuracy, low cost sensor module, long life span (>5 years). In addition, there is no need foe routine calibration.
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.
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.
