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.
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.
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.
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.
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.
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.

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 water PH sensor is high quality, high precession, industrial standard water PH sensor. It is designed to be used in industrial applications such as water treatment facilities, rivers, lakes, peverage industry. The PH sensor equipped with 2 meter low noise cable. It is designed for low power consumption, long life and high measurement stability,
PH is a measure of acidity or alkalinity of a solution. It is commonly used to measure the quality of the water or for water monitoring. The pH scale ranges from 0 to 14.
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
