| "DFRobot DFR0034 Gravity: Analog Sound Sensor For Arduino" |
| "DFRobot Gravity Expansion Shield and Sensors for Arduino - DFRobot DFR0034, This DFRobot Analogue Sound Sensor is compatible with Arduino. A Sound Sensor is typically used to detect the loudness of a sound in its surrounding area.The Arduino can be programmed to collect the sensor's output signal and react accordingly. If you add a buzzer, etc., you could use the sound sensor make an interactive project such as a 'clap and buzz' to find lost keys or the TV remote control. The sensor works best with DFRobot's Audio Analyzer module.DFRobot's IO expansion shield is the best match for connecting the sensor to your Arduino. As the sound sensor can work at 3.3V it is also compatible with Raspberry Pi, Intel Edison, Joule and Curie. DFRobot DFR0034 Gravity: Analog Sound Sensor For Arduino"

| "DFRobot SEN0161 Gravity: Analog pH Sensor / Meter Kit For Arduino" |
| "DFRobot Gravity Expansion Shield and Sensors for Arduino - DFRobot SEN0161, What is pH? 'pH' stands for 'power of hydrogen', which is a measurement of hydrogen ion concentration. The pH scale ranges from 1 to 14, with 7 considered to be neutral. A pH less than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline.Need to measure water quality and other parameters but haven't got a low cost pH meter? The DFRobot analogue pH meter, has been specially designed for Arduino controllers and has convenient and practical 'Gravity' connector plus a host of useful features. It offers instant connection to your probe and your Arduino to get pH measurements at ± 0.1pH accuracy at 25℃. For most hobbyist this is a great accuracy range and it's low cost makes it a great tool for bio-robotics and other projects!The sensor has an LED which works as the power indicator, a BNC connector and PH2.0 sensor interface. To use it, simply connect the pH sensor with BNC connector, and plug the PH2.0 interface into the analogue input port of any Arduino controller.The sensor comes in a compact plastic box with foam for better mobile storage. Build your own pH meter gadget, or a water monitoring station for your water tanks. Use it for your aquaponics or fish tanks or other materials that need accurate pH measurements.

| "DFRobot SEN0114 Gravity: Analog Soil Moisture Sensor For Arduino" |
| "DFRobot Gravity Expansion Shield and Sensors for Arduino - DFRobot SEN0114, The DFRobot soil moisture sensor can read the amount of moisture present in the soil surrounding it. It's ideal for monitoring an urban garden, or your pet plant's water level. This is a must have component for a IOT garden!The soil moisture sensor uses Immersion Gold to protect the nickel probes from oxidation. The sensor uses two probes to pass current through the soil and then it reads that resistance to calculate the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance). The sensor will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.The sensor has a Gravity Interface to allow plug & play operation. The DFRobot Arduino IO Expansion Shield is the best option for connecting the sensor to your Arduino. As this sensor can work at 3.3V it is compatible with Raspberry Pi, Intel Edison, Joule and Curie.Note: If you are going to use the sensor in very humid soil, it may suffer from surface erosion and for this application the use of the DFRobot Analogue Capacitive Soil Moisture Sensor- Corrosion Resistant is rocommended.

| "DFRobot SEN0203 Gravity: Heart Rate Monitor Sensor for Arduino" |
| "DFRobot Gravity Expansion Shield and Sensors for Arduino - DFRobot SEN0203, The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed for Arduino micro-controllers. This heart rate monitor sensor is a pulse sensor which is developed based on PPG techniques. This is a simple and low-cost optical technique that can be used to detect blood volume changing in the micro-vascular bed of tissues. It is relatively easy to detect the pulse component of the cardiac cycle according to this theory.The sensor has two holes that you can use to attach to the belt. You can wrap it on your finger, wrist, earlobe or other areas where it has contact with your skin.The sensor has a Gravity interface allowing plug & play connection. The DFRobot IO sensor shield is the best option to connect this heart rate sensor to your Arduino or other micro-controllers. The sensor can also be used with Raspberry Pi, Intel Edison, Joule and Curie by virtue of its 3.3V input voltage. DFRobot SEN0203 Gravity: Heart Rate Monitor Sensor for Arduino"
