MQ-7 Carbon Monoxide Sensor Module. The sensor detects the concentration of CO (carbon monoxide) and flammable gases. It has a goldpin connector raster 2.54 mm. It is powered by 5 V. It has digital and analogue outputs, which makes it compatible with most runtime modules including Arduino.

The SparkFun weather meter kit is a set of basic mechanical components for building a weather station. This kit represents the three basic elements of weather measurement: wind speed, wind direction and precipitation. Whether you are a farmer, a professional meteorologist or a weather enthusiast, building your own weather station can be a truly rewarding project. However, when it comes to measuring the weather, you need some pretty specialised sensors.

Level sensor for liquids with float. The liquid level sensor acts as a switch. Liquid level float sensors are used when constant control and regulation of the liquid level (water, oil and other fluids) is required such as extraction pumps. The sensor is equipped with a float with a magnet which, acting by the buoyancy force of the fluid, moves along the tube, shortening or opening the reed switch. It can be used to detect liquid levels that are too high or too low. Ideal for all those applications where the level of non-corrosive liquids such as water tanks or aquariums needs to be monitored. It is made of stainless steel.

Gravity: Starter Kit for Arduino is a plug&play electronics toolkit that provides Arduino beginners and makers with the easiest experience of learning and playing with the Arduino platform. The Gravity Kit presented here is equipped with numerous electronic components, such as a motherboard that works with the Arduino Uno - DFRduino Uno v3. DFRobot Gravity IO Expansion shield for Arduino is enclosed as well.

Microwave radar presence and motion sensor using FMCW technology, compatible with Arduino and Raspberry Pi.

Arduino compatible analog TDS (Total Dissolved Solids) sensor to measure water hardness, water purity. It can be used to test water quality in domestic, hydroponic and other applications. Measures TDS from 0 ppm to 1000 ppm. Power supply from 3.3V to 5.5V.

Gravity: IO Expansion Shield for Arduino V7.1 is a shield board for Arduino that expands the capabilities of the I/O pins.  Among other things, it has each pin with a power pair, the ability to include a 3.3 V voltage converter, a separate connector for I2C interfaces, SPI and a socket for XBee modules.

Sparkfun sensor  MyoWare® 2.0 from Advancer Technologies is a newer version of this producer's bestseller. The MyoWare 2.0 muscle sensor included in this kit has been redesigned from the ground up with a new compact and easy-to-use design, and has been updated with the latest, most advanced chipset to improve sensor performance and reliability. In addition, MyoWare has developed a range of shields that work with the sensor (in our LED shield offering, displaying sensor readings as LED lights).

This Cable Shield provides a 3.5mm connector where you can connect a three-electrode sensor cable, allowing you to test and use the MyoWare 2.0 muscle sensor without actually connecting it to your person.

Sparkfun MyoWare 2.0 Muscle Sensor Development Kit  is an all-in-one electromyography (EMG) sensor kit compatible with Arduino. Just snap on a MyoWare 2.0 Shield, add some EMG sensor pads, connect the sensor to a muscle group and flex! The kit also includes the SparkFun RedBoard Plus is an Arduino compatible board and the MyoWare 2.0 Arduino Shield to connect the MyoWare® 2.0 sensor via a cable to the Arduino.

The sensor measures the current flowing in the cable without cutting it. The measurement is made on a single insulated wire, the output is an analog voltage from 0 to 1 V. Sensor SCT-013-000, Non-Invasive 100A AC Current Meter

Pressure sensor sometimes called strain gauge. Load cell for measuring weights up to 50kg. The transducer measures the strain of the metal structure and converts it into a few mV.
