This is a simple breakout board for the MQ - 3, MQ - 4, MQ - 6, MQ - 7, and MQ - 8 gas sensors. With the Gas Sensor Breakout you will be able to utilize each oversized, oddly spaced pins featured on every MQ gas sensor product. This is an extremely handy and economical board to have around when detecting multiple types of gases. All you need is the VCC at 5V, GND, and a resistor to an ADC, that is it! Note: This is just the PCB. The appropriate sensors are listed below in the Recommended...

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance, and a higher SIG out. To get the SparkFun Soil Moisture Sensor functioning all you will...
