Attention
The bottle cap of the probe contains protective liquid (3.3mol/L KCL). Even if the bottle cap is screwed tightly, some protective liquid may still leak around the bottle cap, forming white crystals. But as long as there is still protective liquid in the bottle cap, it will not affect the life and accuracy of the probe. So please use it with confidence. It is recommended that the white crystals be poured back into the protective liquid in the bottle cap.Â

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.
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 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.
This environmental sensor module is based on BME280 powerful environmental sensor. It can sense temperature, barometric pressure, humidity .
You can monitor 2 environmental parameters simultaneously. All the measurements can be read through either I2C or SPI connection.
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 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 is an economical oxygen sensor to measure oxygen concentration (percentage) and gas Volumetric Flow Rate. The sensor measures the gas temperature also.

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.
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.
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.
