Hardware Setup - Basic GRO
In this guide, you will learn how to setup the device from our pre-made kit. First you will learn basic things about breadboards, how they work and what are they used for, and later, by following this simple step-by-step tutorials, get everything up and running!
BME280 - Temperature, Humidity and Barometric Pressure Sensor
For our first component we will be using BME280 sensor - an environmental sensor with temperature, barometric pressure and humidity. This sensor is great for all sorts of weather and environmental sensing and uses I2C communication protocol. Follow the simple steps below and connect your first sensor!
BH1750 - Light Intensity Sensor
Next we will connect BH1750 - ambient light intensity sensor breakout board. Since BH1750 communicates using I2C communication protocol as well, we can connect this sensor in the same way as we connected BME280.
DS18B20 - Waterproof Temperature Sensor
Next we will connect DS18B20 - digital thermometer. The DS18B20 communicates over a One-Wire bus that requires only one data line (and ground) for communication with a microcontroller, so you will be able to set it up very easily.
Soil Moisture Sensor
As a last, but not least, sensor of our basic GRO device, we will add soil moisture sensor - a simple sensor for measuring the moisture in soil and similar materials. This sensor is very easy to use, but please note that sensor is a toy. It's not useful in any real application!
As you've noticed this little device looks a bit messy with jumper cables, so below we will show how you can set it up using solid core wires. This is more elegant version, and will be easy to set up since you have already learned how each sensor work.
