Page 2 Design Brief & Specification Design Brief I am going to design and make a moisture detector to place in a plant pot to indicate whether the soil needs watering or not. An LED will light up if the soil is moist. I will add an acrylic design to place at the top to make it more noticeable and attractive. Specification. My product must: 1Light up when the soil is moist. 2Have neat soldering. 3Be assembled very neatly. 4Have an acrylic design that is related to gardening or the seasons. 5Have an acrylic image that is easily recognised Moisture Detector Name Class Date
