A Temperature and Humidity device is a device that measures both the temperature and humidity levels in the environment. The device usually consists of two sensors, one for temperature and one for humidity, and a display unit that shows the readings in real-time.

Temperature is the measure of the amount of heat energy in the air and is usually measured in degrees Celsius (°C) or Fahrenheit (°F). Humidity, on the other hand, is the amount of moisture or water vapor present in the air and is usually measured as a percentage.

Temperature and humidity devices are available in various forms, including handheld devices, wall-mounted units, and sensors that can be connected to a computer or mobile device. it also additional features such as data logging, alarms, and wireless connectivity for remote monitoring.

If it's used and combined with special sensor Arduino expansion board, it will be easily implemented. If it's used and combined with special sensor Arduino expansion board, it will be easily implemented. The actuator used is a spray pump that is used to spray water into the air to lower the temperature.

The 5V DC Solenoid Water Air Valve Switch specifically operates on a 5V direct current (DC) power supply. It is commonly used in applications that require the control of water or air flow, such as in irrigation systems, pneumatic systems, or aquariums.

A 5V DC Solenoid Water Air Valve Switch is a type of valve that uses a solenoid to control the flow of fluids or gases. The valve consists of a coil of wire, which generates a magnetic field when an electric current is passed through it. This magnetic field then moves a plunger or piston inside the valve, which in turn controls the opening or closing of the valve.

CoAP (Constrained Application Protocol): This protocol is designed for devices with limited processing power and memory, such as sensors and actuators. It is a simple, lightweight protocol that is optimized for use with resource-constrained devices.

This liquid valve would make a great addition to your robotic gardening project. There are two (Nominal NPT) outlets.The flow of fluids as soon as it is powered ON and stops/blocks the flow when the supply voltage removed.

A Soil NPK sensor is a type of sensor that is used to measure the levels of Nitrogen, Phosphorus, and Potassium (NPK) in soil. These three elements are essential for the growth and development of plants, and their levels in the soil can affect the health and productivity of crops.

The stainless steel probe of the soil NPK sensor can be buried in the soil for a long time and is resistant to long-term electrolysis, salt, and alkali corrosion. It helps in determining the fertility of the soil thereby facilitating the systematic assessment of the soil condition.

The use of Soil NPK sensors can provide several benefits to farmers and gardeners. By accurately measuring the NPK levels in the soil, they can avoid over or under-fertilization, which can lead to nutrient imbalances and reduced crop yields. This can also reduce the need for chemical fertilizers, which can be expensive and have negative environmental impacts.

This Capacitive Soil Moisture device measures soil moisture levels by capacitive sensing. It is made of corrosion-resistant material which gives it excellent service life. Insert it into the soil around your plants and get data of soil moisture. Soil Moisture device is controlling the exchange of water and heat energy between the land surface and the atmosphere through evaporation and plant transpiration.

The Capacitive Soil Moisture device consists of two electrodes that are placed in the soil. One of the electrodes acts as a capacitor plate, while the other electrode acts as a ground. When the moisture content in the soil changes, the capacitance between the two electrodes also changes, which is then measured by the sensor.

Capacitive Soil Moisture devices is used in a variety of settings, such as agriculture, landscaping, and gardening. They are particularly useful in precision irrigation systems, where water can be applied only where and when it is needed, resulting in more efficient water use and reduced water waste.

Capacitive Soil Moisture devices also come with additional features, such as temperature sensors or wireless connectivity, which can provide additional information about the soil conditions and allow for remote monitoring.

The soil PH device is a high functional and digital display soil tester, it can quickly test PH of different kinds of soil. The soil meter is precision, quick, stable, wide range, display clear, portable and easy to test. Soil pH meters are devices used to measure the acidity or alkalinity of a soil.

Soil pH is a measure of the concentration of hydrogen ions (H+) in the soil, and it is an important factor that affects the availability of nutrients to plants.

The Soil pH device works by measuring the electrical potential difference between two electrodes that are inserted into the soil. The electrodes are usually made of a reactive metal such as silver or copper, which reacts with the soil and generates an electrical current that is proportional to the soil pH.

The readings provided by the Soil pH device are usually given on a scale of 0 to 14, with 7 being neutral. A soil pH of less than 7 is considered acidic, while a pH greater than 7 is considered alkaline. Most plants grow best in a slightly acidic to neutral soil, with a pH range of 6.0 to 7.5.
