If pre-programmed, you will get the pH value easily. To use it, just connect the pH sensor with BND connector, and plug the PH2.0 interface into the analog input port of any Arduino controller.

Some of the most common applications with Arduino are: Home lighting, electrical appliances of high power and other equipments. Gravity 3 pin interface Analog voltage output High. Gravity: Digital 5A Relay Module DFRobot DFR0017 The DFRobot Relay Module is a standard relay used with a controller board to interface external electrical circuits or modules. For most hobbyist this great accuracy range and it’s low cost makes this a great tool for biorobotics and other projects! It has an LED which works as the Power Indicator, a BNC connector and PH2.0 sensor interface. And please be careful careful careful with the high voltage circuit. Instant connection to your probe an your Arduino to get pH measurements at ± 0.1pH (25 ℃). display performance and is fully compatible with the driving circuit or program. This Analog pH Sensor / Meter Kit, specially designed for Arduino controllers and has convenient and practical “Gravity” connector and a bunch of features. Gravity: Digital RGB LED Module is a cascadable single RGB LED module. Simply clamp the AC transformer probe on. The level transmitter receives different pressures at different depths of liquid, which can be converted into corresponding current signals and output through the sensor. The Gravity: Analog AC Current Sensor comes to the rescue, eliminating the need to cut wires or reconnect circuits.

Gravity SD2405 RTC can work as data logger, timer alarm clock and other. Board Dimension : 21 * 27.11 mm/ 0.83 * 1.Gravity: Analog pH Sensor / Meter Kit For Arduino® This throw-in type liquid level transmitter adopts high-performance pressure sensing chip, with advanced circuit processing and temperature compensation technology. The product incorporates a time trimming circuit that adjusts the clock with.Needs a 5V power supply, even if you are using a 3.3V microcontroller.Compared with the previous version of the soil moisture sensor, it has increased waterproof performance, optimized corrosion resistance, increased plate length and optimized circuit performance. This is a new type of waterproof soil moisture sensor introduced by DFRobot. It can be widely used in HVAC refrigeration and indoor air quality monitoring, industrial process and safety monitoring, agricultural and animal husbandry production process monitoring. DFRobot Gravity: Analog Waterproof Capacitive Soil Moisture Sensor. The analog output is designed to be compatible with. These sensors read the AC current value by clamping the AC transformer probe on the AC line and plugging 3.5mm headphone jack into the signal conversion-module. It has characteristics such as wide range detection, high sensitivity, high resolution, low power consumption, fast response, anti-water vapour interference, no poisoning, high stability and long life. DFRobot Gravity: Analog AC Current Sensors eliminate the need to cut wires or reconnect circuits in order to measure the AC current. In addition, this UART Infrared CO2 Sensor is a high-performance sensor that combines the technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design. It also has a long service life, up to 5 years! Most importantly, the product is easy to use it is compatible with all types of microcontrollers with a UART port, such as Arduino, Raspberry Pi and other microcontrollers. It integrates temperature compensation and supports UART communication mode. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. This wide-range infrared CO2 sensor from DFRobot has an effective range of up to 0~50000ppm. Easy relay module uses a standard Gravity sensor interface and supports a wide voltage input of 3.3V-5.5V, making it easy to connect with main control.
