ANAVI Gardening uHAT is a low-cost, open source Raspberry Pi add-on board that helps you develop smart solutions for monitoring and growing plants. The kit includes one ANAVI Gardening uHAT and two capacitive soil moisture sensors.
ANAVI Gardening uHAT supports multiple sensors for soil moisture, temperature, humidity, barometric pressure, and light. Getting started is easy - just plug it into a Raspberry Pi with your bare hands and follow the instructions in the user manual. No soldering is necessary and no tools are required.
ANAVI Gardening uHAT features:
Slots for up to two capacitive soil moisture sensors
Slot for a waterproof temperature sensor
Slots for up to two plug-and-play I²C sensors
UART pins for serial communication
GPIO pins for controlling irrigation systems and peripherals
Green and red indication LEDs
Microchip MCP3002 analog-to-digital converter (ADC)
Follows uHAT mechanical specification with a valid ID EEPROM
Excellent software support, documentation, and open source examples
ANAVI Gardening uHAT works with any Raspberry Pi single board computer (SBC) with a 40-pin header, including Raspberry Pi 4 and Raspberry Pi Zero W.
ANAVI Gardening uHAT officially supports the following sensors:
Capacitive soil-moisture sensors (two included in each kit)
DS18B20 1-wire waterproof temperature sensor
HTU21D I2C sensor for temperature and humidity
BH1750 I2C sensor for light
BMP180 I2C sensor for barometric pressure
Note: You can attach any other I²C device or sensor, but you will have to take care of their software integration.
ANAVI Gardening uHAT combines open hardware with free and open source software. The printed circuit board was designed with the free and open source tool KiCad. The first prototype was created in 2017, but it relied on resistive soil-moisture sensors, which were vulnerable to corrosion. After that, the project was put on hold for several years.
In 2021 we revived the project using Microchip’s MCP3002 analog-to-digital converter (ADC) and low-cost capacitive soil-moisture sensors made of corrosion-resistant materials.
There are literally hundreds of automated-gardening solutions on the market. Unlike the rest, ANAVI Gardening uHAT is simple, affordable, easy to use, and extremely powerful in the hands of a skilled maker.
If you are new to the Raspberry Pi ecosystem, don’t worry. Not only is this project entirely open source, it is designed to help newcomers to the Raspberry Pi ecosystem get started easily, thanks to its documentation and helpful sample code.
ANAVI Gardening uHAT was brought to life in 2017 thanks to a crowdfunding campaign at Crowd Supply.
