Soil Moisture Sensor Kit

Never fear the knights that say Ni again! Use our soil moisture sensor to keep your houseplants and various bits of shrubbery in tip-top condition! The moisture sensor board features both analogue and digital outputs. The analogue output gives a variable voltage reading that allows you to estimate the moisture content of the soil (using some maths!). The digital output gives you a simple "on" or "off" when the soil moisture content is above a certain value. The value can be set or calibrated using the adjustable onboard potentiometer. The sensor features a nickel-plated anti-rust spade, and a wide sensor to ensure accurate moisture readings. The module uses the LM393 "comparator" chipset to measure the moisture content. Features
