This is a photoelectric liquid level sensor that is operates using traditional optical principles. The advantages of this are a high sensitivity and no need for mechanical parts – meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperatures and high pressures. The sensor is equipped with an interface adapter for compatibility with the DFRobot “Gravity” interface.

Note: Avoid placing the sensor near bright lights or in direct sunlight as these can cause interference.

Conductivity is the reciprocal of an object’s resistivity. It represents a material’s ability to pass a current. In a liquid, conductivity is a measure of a solution’s ability to conduct electricity and can reflect the amount of dissolved or salinity of a water source, so it’s an important parameter in water quality monitoring. DFRobot Gravity: Analog Electrical Conductivity Sensor PRO(K=1) is specially used to measure the conductivity in aqueous solutions, and then to evaluate the water quality. These conductivity sensors are often used in hydroponics, aquaculture, environmental water detection, and other fields.

As an upgraded version of the analog electrical conductivity meter, this pro version has greatly improved probe endurance, which can be used in 24/7 conductivity monitoring. Besides, the integrated PT1000 platinum resistance thermometer makes it easier to measure the compensated temperature data.

Features:

1. Easier to measure the compensated temperature data
2. Plug-and-play, no solder required
3. The output signal is filtered by hardware and has low jitter.

Package includes:

1 x Industrial Grade Analog Electrical Conductivity Sensor PRO (K=1)
