For this project, we're using a Raspberry Pi Zero WH, with built-in Bluetooth and Wi-Fi, and a pre-soldered GPIO header.

The Sense Hat works with Raspberry Pi 2 Model B and later, so if you've upgraded and have an old Pi hanging around, this is a great way to give it a useful second life. If you don't have a greenhouse, you could use the same technique to monitor the temperature of, say, a nursery, a vivarium housing reptiles or even just your office. You don't need Wi-Fi if you only want to record your measurements onto the SD card, but you will if you want to upload them to the server, so make sure your network signal carries far enough, or use a booster. If you're going to use it in an outbuilding, you should also make sure it isn't going to get wet. Naturally, you need a power source wherever you position your Pi plus Sense Hat. That way, if you mount the Pi so it's visible from the house, you can see at a glance if you need to go out and turn on a heater or open a window, even if you haven't checked the server. We'll also make use of the LED matrix mounted on the Sense Hat's top surface to give visual feedback should temperatures stray outside of a defined range. We'll therefore take a reading every 15 minutes and upload the data to a web server so it can be checked from the comfort of a centrally heated home. With winter on the way and gardeners moving vulnerable plants under cover, it makes sense to have a way of keeping an eye on conditions without having to go out and check a thermometer. To showcase the Sense Hat's capabilities, we'll focus on three of those sensors – temperature, humidity and pressure – to build a greenhouse-monitoring system. Here at IT Pro, we're a little more down to earth. The European Space Agency has even sent two of them to the International Space Station for conducting experiments in weightless environments.

The example code displays a simple text menu that allows you to capture data, control the digital I/O pins, set up the signal generator and drive the LED.ĭownload the driver and example code, and read the latest Raspberry Pi news, on the Pico forum here.The Raspberry Pi Sense Hat is a versatile add-on, with sensors for temperature, humidity, pressure, orientation and direction, and there are numerous examples of how it can be used online.

Pico Technology has released a Debian driver and C++ example code for free download. When connected to the Raspberry Pi single-board computer, DrDAQ forms a powerful data logging system that can be integrated into your custom Linux application. DrDAQ requires just a single USB connection for power and data.

There are also three inputs for Pico’s own sensors or for custom devices that you can build yourself. Now your Linux application can have access to a 100kHz oscilloscope, arbitrary waveform generator, four digital I/Os (two with pulse-counting input and PWM output), 24-bit RGB LED, built-in light sensor, temperature sensor, microphone and sound level sensor, resistance measuring input and pH/redox sensor input.
