This demonstrates the conversion of an analogue to a digital signal; its display as a histogram; and the generation of a control signal when a threshold signal value is reached. Directions Step 1: Setup Plug a potentiometer into P4 and a LED into P2 using the 3-wire leads. Step 2: Running the app Navigate to the …
This WaterMe app measures moisture in soil (or any other medium) using a resistive soil moisture sensor or a capacitive soil moisture sensor. When the moisture falls below an adjustable threshold level. a control signal is sent to a Mosfet Output Module which connects power to a 3-6v mini-pump. When the moisture level rises to above the threshold level, the …
