If you're like me and have trouble keeping your calatheas and pepperomias happy and not overwatering them to root rot ruin, why not take a gander at the Plant Monitor from Ada-friend Monk Makes. Its a super easy and friendly way to get started with sensing & gardening projects with no soldering required.
This garden-stake-looking PCB gives you capacitive measurement of soil moisture. Capacitive measurements use only one probe, don't have any exposed metal, and don't introduce any DC currents into your plant friends and you wont get corroded contacts after a few months. Not only can it measure soil moisture but also temperature and relative humidity measurement.
It's compatible with the BBC micro:bit, Raspberry Pi, Pico, Pico W, and most microcontroller boards. Best used with boards that have alligator clip pads like the micro:bit.
- Alligator / croc clip rings
- Ready soldered header pins for your fav microcontroller
- Easy to use UART serial interface
- Additional analog output for moisture only
- Built-in RGB LED
Jargon buster
Plain-language definitions for the technical terms used above.
- alligator clip
- An alligator clip is a spring-loaded metal clip used to make temporary electrical connections to wires, terminals or test points. It is useful for quick bench testing, but it is less secure than a screw terminal or locking connector.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
