It is made from a corrosion-resistant material giving it a long service life. Simply insert it into the soil and impress your friends with the real-time soil moisture data!The sensor includes an on-board voltage regulator which gives it an operating voltage range of 3.3 to 5.5V. It is compatible with low-voltage MCUs (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required. The sensor is compatible with the DFRobot 3-pin 'Gravity' interface, so it can be directly connected to the Gravity I/O Expansion Shield.

Conductivity is an important parameter of water quality. It can reflect the extent of electrolytes present in water.The DFRobot Gravity: analogue electrical conductivity meter V2 can be used to measure the electrical conductivity of an aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detection and other fields.This upgraded version of the electrical conductivity meter V1, greatly improves the user experience and data precision. It supports 3 to 5V wide voltage input, and is compatible with 5V and 3.3V main control boards. The output signal is filtered by hardware has low jitter; The excitation source adopts an AC signal, which effectively reduces the polarization effect, improves the precision and prolongs the life of the probe; The software library uses the two-point calibration method, and can automatically identify a standard buffer solution, making it simple and convenient.With this sensor, main control board (such as Arduino) and the software library, you can quickly build an electrical conductivity meter, plug and play, with no soldering. Tip: in order to ensure the measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature to achieve automatic temperature compensation.

It can be used for environmental noise testing, such as a highway noise monitoring station, bedroom noise monitoring, etc. Nowadays, there are many kinds of sounds surrounding us, some of which are very loud. It is essential to measure whether the sound is noisy enough to do damage to our health.This sound level meter is compatible with Arduino and is plug-and-play with no soldering required. It supports 3.3 to 5.0V input voltage, 0.6 to 2.6V voltage output. The decibel value is linear with the output voltage, which gives a simple conversion, without complex algorithms.

| "DFRobot Gravity Expansion Shield and Sensors for Arduino - DFRobot SEN0161-V2, The pH is a value that represents the acidity or alkalinity of a solution. It is also called the hydrogen ion concentration index. The pH is a scale of hydrogen ion activity in a solution. pH has a wide range of uses in medicine, chemistry, and agriculture. Usually, the pH is a number between 0 to 14. Under the thermodynamic standard conditions, pH=7, which means the solution is neutral; a pH<7 means the solution is acidic; a pH>7 means the solution is alkaline.The DFRobot Gravity: Analog pH meter V2 is specifically designed to measure the pH of a solution and reflect the acidity or alkalinity. It is commonly used in various applications such as aquaponics, aquaculture and environmental water testing.As an upgraded version of pH meter V1, this product greatly improves the precision and user experience. The on-board voltage regulator chip supports the wide voltage supply of 3.3 to 5.5V, which is compatible with 5V and 3.3V main control boards. The output signal filtered by hardware has low jitter. The software library adopts the two-point calibration method, and can automatically identify two standard buffer solutions (4.0 and 7.0), making it simple and convenient.With this product, main control board (such as Arduino) and the software library, you can quickly build a pH meter, plug and play, with no soldering.
